What are the major parts of a cell and their functions?
Cell Parts and Functions
| A | B |
|---|---|
| Nucleus | Regulates all cell activities |
| Cell Membrane | Is made out of phospholipids and proteins |
| Mitochondrion | Site of cellular respiration “power house” |
| Lysosome | Suicide Sacks that contain digestive enzymes |
What are the three main parts of the cell nucleus?
The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm; and the nuclear matrix (which includes the nuclear lamina), a network within the nucleus that adds mechanical support, much like the …

What cell is made of?
All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids.
Are human made of cells?
The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.
What are the functions of a cell?
Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.
Why do we need to study the cell?
By understanding how cells work in healthy and diseased states, cell biologists working in animal, plant and medical science will be able to develop new vaccines, more effective medicines, plants with improved qualities and through increased knowledge a better understanding of how all living things live.
