- Serves as a boundary between the cell and its environment.
- Control the passage of materials in and out of cells.
Cell wall
- Gives support to the plant cell as a whole by providing mechanical strength.
- Allows the movement of water.
- Prevent plant cell from bursting.
Cytoplasm
- Contains substances such as enzyme, oil droplets, glycogen granules (in animal cell only), and starch grains (in plant cell only).
Nucleus
- Contains the genetic material of a cell in the form of chromosomes.
- Acts as a control centre for the activities of a cell.
- Produces ribosomes and ribonucleic acids (RNA).Plays as essential roll in cell division.
Rough endoplasmic reticulum
- Involves synthesis of proteins.
- Provides a pathway for the transport of materials in the cell (intracellular transport system).
- Provides a large surface area for chemical reaction.
Smooth endoplasmic reticulum
- Produces lipids.
Mitochondria
- Site of aerobic cellular respiration.
- Produces adenosine triphosphate (ATP).
Golgi apparatus
- Collects, packs and distributes molecules synthesized in the cell.
- Products glycoproteins, polysaccharides and secretory enzymes.
- Forms lysosomes.Transports and stores lipids.
Lysosome
- Digests materials which the cell consumes.
- Destroys unwanted or worn out organelles.
- Completely breaks down the cell after its death.Releases enzymes outside the cell to digest external material.
Ribosome
- Site of protein synthesis.
Centriole
- Forms the spindle during the cell division of animal cell.
Vacuole
- Stores anthocyanins which provide various colours to fruits and flowers.
- Stores sugars and amino acids in its sap.
- Stores organic wastes in vacuoles of leaf cellsSupports herbaceous plants by turgor pressure.
Chloroplast
- Site of photosynthesis.
