Structural Organisation in celll
The cell is the structural and functional unit of any animal or plant and consists of various cellular components that carry out the functions of the cell. These structures are called cell organelles.
The cell organelles and its Functions as follows:
| Cell organelle | Function |
|---|---|
| Nucleus | The nucleus contains the hereditary material (DNA) surrounded by nuclear envolope which separates the DNA from the rest of the cell |
| Endoplasmic reticulum | Plays a major role in metabolism of carbohydrates, synthesis of lipids, proteins and steroids |
| Cytoplasm | Thik jelly-like substance that houses various cell organelles. Some chemical reactons takes place within the cytoplasm |
| Golgi apparatus | Transportation of materials within the cell |
| Mitochondrion | Store energy in the form of ATP. |
| Ribosome | Also known as protein factory of the cell, proteins are synthesized here |
| Lysosome | It engulfs foreign bodies that enter in the cell and helps in renewal of cell. |
| DNA | Deoxyribonucleic acid, DNA is genetic material of the cell |
| Cell membrane | Protect and support the cell and regulates the substances movement in and out of the cell. It has porous and a wall-like structure between two cells |
