Intro riff: (does not include timing: add additional 8th notes as needed) play the notes G A B C C C D E E D C D C B C LYRICS C .........................G I went into a cell, to get out of the rain, ........C ........................................G ...........C and there was the gatekeeper, the cell membrane. I went into a cell, and what did I see, the mitochondria, it's the energy factory. I went into a cell, and said "who drives this bus" and found myself talking to the boss, the nucleus. I went into a cell, to recover from a spasm, and found myself swimming in some clear cytoplasm. I went into the nucleus to ask how to get home, and got genetic info, stored in a chromosome. I went into a cell, and stretching o' so far, was a thin and wavy network, it's called the E.R. I went into a cell, trying not to be perplexed, by the packaging and sorting in the Golgi complex. I went into a cell, and said "who makes proteins here?" and somebody responded "it's the ribosome, my dear." I went into a cell, and was feeling pretty fine, till a lysosome engulfed me, and dissolved me in enzymes. I went into a cell, and was feeling pretty nimble, till a centriole lassoed me, tying me up in a spindle. I went into a plant cell to see how trees get so tall, and all around the outside was a rigid cell wall. I went into a plant cell, "why's it so green I asked?" "'Cause I make food from sunlight," said a green chloroplast. I went into a plant cell to see how plant cells store food, when a vacuole informed me that he was the storage dude. So when you go inside a cell, remember what you see, There's over a trillion cells in both you and me. Just sing this song if you ever feel confusion, and remember active transport is the opposite of diffusion.
Cells for kids is an engaging and fun look at the function and structure of cells. In this video we compare the differences between animal and human cells vs plant cells. We first identify the parts of a cell including the Nucleus, Cytoplasm, Cell Membrane. We then explore the difference between human or animal cells and plant cells including chloroplast and the cell wall. We learn about each of these parts and their function within the cell. Cells make up every living thing! They are important to learn about and once your kids are done watching this video they will be able to define cell, identify a difference between a plant and animal cell, and label basic parts of a cell.

Chorus: Cells, cells they're made of organelles Try to pull a fast one, the cytoplasm gels The nucleus takes over controllin' everything The party don't stop 'till the membrane blocks the scene Inside the vacuole we can float around for hours Running round with chloroplasts, lovin' sunlight showers Cells, cells, they're made of organelles First things first, there's two different types- animal and plant cells that make up all life. The little things that make up microscopic cells, The main structures- yeah, we call them organelles. Now let's break it down and get some information- How do cells work? It's a crazy combination! -Chorus- The cell membrane is the border patrol, Who can cross over? The membrane lets 'em know The gooey stuff inside, is called the cytoplasm It holds the organelles- don't worry, plasm-has 'em! In the middle of the cell you'll find the big brain, The nucleus surrounded by nuclear membrane Don't forget the vacuole filled up with water It's a basic need for life when this rap keeps getting hotter! -Chorus- The mitchondria's something every cell needs, Breaking down the food and releasin' energy. There's a place inside the cell where chemicals are stored, the squiggly golgi bodies, releasin' even more. Yo hangin' in the cell is endoplasmic reticulum, synthesizin' enzymes for respiration, and um... If you still think that this rap is whack, remember ribosomes making proteins gettin' jacked! -Chorus- Lookin at the plant cell, weird and green two more parts is all it takes you see? Cell wall knows what's up when it comes to keepin' structure Strong with cellulose, this cell can't get much tougher.

🤍 Plants and animal cells share many similarities since they are both eukaryotes, which means that they have a membrane-bound nucleus. Plant cells are often larger than animal cells. Well… except eggs… the largest animal cell is an unfertilized ostrich egg, which weighs around 1.5 kg!!! So let’s discuss similarities! Both animal and plant cells have membrane-bound organelles. They also both have cytoplasm, a cell membrane, a nucleus, mitochondria, rough and smooth endoplasmic reticulum, a Golgi apparatus, and peroxisomes. The nucleus is where the genetic information of the cell is housed. The cytoplasm is not to be confused with the cytosol. The cytoplasm is the entirety of the cell contained by the cell membrane. The cytosol on the other hand is the part of the cytoplasm not taken up by organelles. The cell membrane is an important semi-permeable division between the cell and its surroundings. It allows the cell to control its own biochemistry by only letting certain substances through it. Mitochondria are the powerhouses of the cell. They are specialized to perform aerobic respiration, converting glucose to ATP, which is the energy currency of the cell that is used to perform functions necessary for life. Both rough and smooth endoplasmic reticulum help with the production and storage of proteins. The rough endoplasmic reticulum is covered in ribosomes, which translate RNA into protein. The smooth endoplasmic reticulum makes lipids. The golgi apparatus modifies proteins. Peroxisomes metabolize waste. Now let’s get to the differences between plant and animal cells. One major difference is that plant cells have a rigid cell wall around their plasma membrane. It is composed of cellulose, providing additional stability and protection. As a result, plant cells have fixed, angular shapes, while animal cells are mostly round and irregular. Another important difference between animals and plants is how they obtain their energy. Plants are autotrophs, which means that they produce their own food. Meanwhile, animals are heterotrophs, meaning that they must ingest their food. Plants produce sugars through photosynthesis, and then break down the sugar to produce energy. Animals consume other organisms such as plants to obtain sugar, which they then also break down to produce energy. Again, the sugar is broken down in mitochondria. Plants are autotrophs thanks to special organelles called chloroplasts, which are full of chlorophyll, a green pigment that captures light energy to drive the reactions in photosynthesis. Photosynthesis is the process by which plants use the sun’s energy to make sugar. Once the sugar is made, it gets broken down in mitochondria. Another important difference between plant and animal cells is in their vacuoles. Vacuoles in plant cells can occupy up to 90% of cell’s volume and have a single membrane. One of their roles is simply to fill up space but they can also have digestive functions similar to lysosomes. Vacuoles have enzymes that perform many functions and can store nutrients or provide space to degrade waste substances. Animal cells can also have vacuoles, but they are MUCH smaller than the large central vacuole in plant cells and there are multiple of them and they don’t take up 90% of the space. Plant and animal cells both also have cytoskeletons, which feature microtubules, intermediate filaments, and microfilaments. However, these structures are arranged differently in plant and animal cells. Centrioles are present in all animal cells but only in lower plant forms such as Chlamydomonas. Centrioles are microtubule organizing centers, which are structures from which microtubules emerge. Plants don’t have centrioles, but instead have many small nucleation sites. In plants – only gametes can have flagella – such as the sperm of bryophytes. Some animal cells also have flagella. In humans, sperm are the only cells with flagella, however, many animal cells have cilia, unlike most plant cells. For example, we have cilia in our respiratory system which help remove debris and mucus, in the female reproductive system to help sperm move towards the egg, and elsewhere. Animal cells have clearly-defined lysosomes. It’s still debated whether some plant cells have them though. Lysosomes are membrane-bound spherical vesicles containing hydrolytic enzymes that can break down biomolecules. They are involved in cell processes like secretion, plasma membrane repair, cell signaling, and energy metabolism. Plant cells also have plasmodesmata, which are channels that connect two plant cells. An analogous structure in animal cells is the gap junction, which connects the cytoplasm of two adjacent cells.

Animal Cell. The Animal cell is surrounded by a semi-permeable cell membrane. The cell membrane allows only specific materials to move in and out of the cell. The different parts of the cell are called organelles. Nucleus, Mitochondria, Endoplasmic Reticulum, Golgi Apparatus, Lysosomes. The cytoplasm is a jelly like substance. Cytoplasm provides a surface for all the organelles in the animal cell. Nucleus being the control center of cell decides and controls most of the functions going on in the cell. Mitochondria are the sites for cellular respiration in cells. They are the powerhouses of the cell because they release energy rich compounds called ATP. ATP is needed for the functioning, growth and maintenance of the body. Let us now study about the endoplasmic reticulum. The endoplasmic reticulum is a large network of membrane bound sheets. They help in transporting and exchanging materials between the various regions of the cytoplasm. The endoplasmic reticulum is of two types: The smooth endoplasmic reticulum The rough endoplasmic reticulum. The smooth endoplasmic reticulum helps in the formation of lipids. Lipids are essential components of the cell membrane. The rough endoplasmic reticulum has ribosomes. Ribosomes help in building proteins in the rough endoplasmic reticulum. The protein is processed inside the golgi apparatus. The proteins are packaged and sent outside. The golgi apparatus is involved in the formation of lysosomes. The lysosomes contain powerful digestive enzymes that help in cell digestion. When the cell is damaged, the lysosome bursts. After the lysosome bursts, digestive enzymes get released. The digestive enzymes digest their own cell. Hence, lysosomes are called suicide bags of the cell.

Along with the skin, the gut mucosa represents the first line of defense against environmental factors. In the gut mucosa, a recently discovered type of lymphocytes called innate lymphoid cells (ILCs) maintain tissue homeostasis, orchestrate tolerance to food or commensal bacteria and contribute to immune responses to pathogens. This Nature Video shows the complexity of ILC biology in the gut mucosa at steady state and disease.

This 16 minute video tells the story of one of this century's most extraordinary scientific discoveries - induced pluripotent stem cells, or iPS cells. Medical doctor and scientist Shinya Yamanaka describes his Nobel prize-winning work. Together with other leading stem cell researchers, he talks about the scientific, medical and ethical implications of his reprogramming experiments. Cameron Duguid's distinctive animations take us inside the reprogrammed cell, and bring the science to life on screen. Suitable and accessible for general audiences and biology students aged 16+. More about the film: 🤍 - we welcome comments there! You can also read more about iPS cells and embyronic stem cells in our FAQ at 🤍 and about ethical issues surrounding iPS cells in our fact sheet at 🤍
What Are Stem Cells | Genetics | Biology | FuseSchool Our bodies are the ultimate factory. Every cell has its specific job to do, and is shaped to do that job perfectly. The fate of each cell is determined during the embryo stage, and then cannot be changed. However, cutting-edge research made a major discovery for modern science: there are these wonderful cells that exist called stem cells. These cells have the ability to become any type of cell because they are not specialised. Scientists were hugely excited by their discovery because they can be used to repair damaged organs, bones or cartilage. They could also be used to help treat diseases, such as by making new brain cells to treat people with Parkinson’s disease. Or they could be used to repair damaged immune systems, and even reverse paralysis or regrow lost limbs. The discovery of stem cells is huge for modern medicine, and could have a massive impact. There are two types of stem cells in humans: embryonic stem cells and adult stem cells. Embryonic stem cells are unspecialised cells that can develop into any type of cell. Adult stem cells are also unspecialised cells but whilst they can develop into many types of cell, unlike embryonic stem cells, they cannot develop into every type of cell. Adult stem cells come from tissues such as bone marrow. As in the name, embryonic stem cells can be removed from unused embryos such as those left over from fertility treatments for example. Whilst the discovery of stem cells offers huge potential for modern medicine, there are many social and ethical considerations that need to be taken into account. A lot of research was, and still is, needed to find out exactly how they work and how we can control them to do what we want; and not just grow uncontrollably. Stem cells are already being used in treatments. One big social and ethical debate around stem cells is therapeutic cloning. This is the concept of cloning a patient, growing an embryo from the cloned cells and then extracting stem cells from the embryo to grow the specific organ needed by the patient. The patient’s body would not reject this organ, as it is a made from the patient’s own cells. Unspecialised stem cells also exist in plants and can develop into the cells of flowers, roots, or leaves. Unlike in animal cells, some plant cells do remain unspecialised and can then develop into any type of plant cell. The unspecialised plant cells group together into structures called meristems. Whereas animals stop growing in size when they are adults, plants do not. This is because meristems divide to produce cells thus enabling plants to continue to grow both in height and width throughout their life. They also produce cells that develop into flowers and leaves. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

View full lesson: 🤍 How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division. George Zaidan explains how rapid cell division is cancer's "strength" and also its weakness. Lesson by George Zaidan, animation by TED-Ed.
Sub culturing (aka passaging), is the removal of the medium and transfer of cells from a previous culture into fresh growth medium, a procedure that enables the further propagation of the cell line or cell strain. The growth of cells in culture proceeds from the lag phase following seeding to the log phase, where the cells proliferate exponentially. When the cells in adherent cultures occupy all the available substrate and have no room left for expansion, or when the cells in suspension cultures exceed the capacity of the medium to support further growth, cell proliferation is greatly reduced or ceases entirely . To keep them at an optimal density for continued growth and to stimulate further proliferation, the culture has to divided and fresh medium supplied.
