The cell
Storyboard Text
- Hello there my name is Rose and today I'm gonna talk about The Cell
- The cell is the basic structural and functional unit of life. Every cell consists of a cytoplasm enclosed within a membrane, which contains many bio molecules such as proteins and nucleic acids. Humans are made up of trillions of cells.
- Inside the cell,different cell types can look wildly different, and carry out very different roles within the body.
-
- CytoplasmThe cytoplasm is part of a cell that is the interior of the cell that surrounds the nucleus and is around 80 percent water
- NucleusThe nucleus is part of a cell that can be thought of as the cell’s headquarters.The nucleus contains the majority of the cell’s DNA
- CytoskeletonThe cytoskeleton can be considered the scaffolding of the cell. It helps it maintain the correct shape.
- Lysosomes and peroxisomesBoth lysosomes and peroxisomes are essentially bags of enzymes. Lysosomes contain enzymes that break down large molecules. Peroxisomes contain enzymes that destroy toxic materials, including peroxide
- Endoplasmic reticulumThe endoplasmic reticulum (ER) processes molecules within the cell and helps transport them to their final destinations.
- Golgi apparatusOnce molecules have been processed by the ER, they travel to the Golgi apparatus.
- RibosomesIn the nucleus, DNA is transcribed into RNA (ribonucleicacid), a molecule similar to DNA, which carries the same message. Ribosomes read the RNA andtranslate it into protein by sticking together amino acids in the order definedby the RNA..
- MitochondriaOften referred to as the powerhouse of the cell,mitochondria help turn energy from the food that we eat into energy that thecell can use — adenosine triphosphate (ATP).
