animal cell
Animal cells lack cell walls and chloroplasts. They contain organelles such as a nucleus that houses DNA, mitochondria that generate energy, rough and smooth endoplasmic reticulum that produce proteins and membranes, vacuoles that export waste, and ribosomes that synthesize proteins. The cell membrane encloses the cell and controls what enters and exits, while the cytoplasm contains water and proteins and is where cellular activities occur.

- 2. About animal cells •An animal cell is a form of eukaryotic cell or cells with a membrane-bound nucleus. • They lack cell walls, plastids and chloroplasts. • The shape of the animal cell is not rigid but is of any shape and size.

- 5. • Cell membrane Theanimal cell has a plasma cell membrane encloses the cell contents. Its main function is to control what gets into and out of the cell.
- 6. • Cytoplasm The cytoplasmcontains primarily water and protein material. This is where the other cell organelles reside, and where most of the cellular activities take place.
- 7. • Nucleus The nucleusgenerally contains the genetic material for the cell. Because it contains the DNA and chromosomes, which affect the proteins that determine the activities of the cell, the nucleus can be considered to be the cell's control center.
- 8. • Rough ER Therough endoplasmic reticulum manufactures membranes and secretory proteins. The rough ER also produces antibodies.
- 9. • Smooth ER Thesmooth endoplasmic reticulum is tubular in form and is involved in the synthesis of phospholipids, the main lipids in cell membranes.
- 10. • Vacoule A vacuoleis a membrane-bound organelle which is present in all plant and fungal cells and some protist, animal and bacterial cells. It exports unwanted substances from the cell.
- 11. • Ribosomes Free ribosomesusually make proteins that will function in the cytosol, while bound ribosomes usually make proteins that are exported or included in the cell's membranes.
- 12. • Mitochondrion Mitochondria, knownas the engine house of the cells, are the organelles that convert energy to forms that cells can use for work. Oxygen combines with glucose to form energy (ATP) required for metabolism and cellular activities in this organelle.
