Functions of different parts of the cell.

The nucleus ensures that the cell is working properly which is like the brain of the cell.
It contains the genetic information of the plant and can be extracted for gentic enginerring.
Without the nucleus the cell will die.

The cell membrane is composed of protein and lipid (fat) molecules. It acts as a boundary layer to contain the cytoplasm (fluid in cell) and interlocks surfaces bind cells together. It is also
selectively permeable to select chemicals that pass
in and out of cells.

The cytoplasm consists of water, salt, organic molecules, as well as enzymes which help catalyze the reactions with the cytoplasm. It holds together all of the cell's organelles, and divides the organelles within the cell.

The cell wall is a non-living secretion of the cell membrane, composed of cellulose. The cellulose fibrils are deposited in alternating layers for strength. It contains pits (openings) that make it totally permeable. It provides protection from physical injury and together with vacuole, it provides skeletal support. Thus giving the cell a shape.

The vacuole is a single layer of unit membrane that encloses fluid in a sack. It produces turgor pressure against cell wall for support. It also stores water and various chemicals including insoluble wastes.


The chloroplasts contains a greenish subtance called chlorophyll.
chlorophyll enables the plant to trap sunlight and thus it is very important without chlorophyll the plant cannot trap light and cannot photosynthesise and then the plant will die eventually.
