• Control centre of the cell
• Stores the organism's genome
• Transmits genetic information
Provides the instructions for protein synthesis
1 of 13
Function of the RER
• RER is the intracellular transport system
• It provides a large surface area for ribosomes, which assemble amino acids into proteins.
These are transported to the Golgi apparatus for modification and packaging.
2 of 13
Function of the SER
• Synthesis of cholesterol
• Synthesis of lipids/phospholipids needed by the cell
• Synthesis of steroid hormones.
3 of 13
Function of the Golgi
Proteins are modified for example by:
• Adding sugar molecules to make glycoproteins
• Adding lipid molecules to make lipoproteins
Being folded into their 3D shape

Function of the Mitochondria
• Mitochondria are the site of ATP production during aerobic respiration.
• They are self-replicating, so more can be made if the cell's energy needs increase.
• They are abundant in cells where much metabolic activity takes place

Function of the chloroplast
• Chloroplasts are the site of photosynthesis.
6 of 13
Function of the vacuole
• Only plant cells have a large permanent vacuole.
• It is filled with water and solutes and maintains cell stability, because when full it pushes against the cell wall, making the cell turgid.
• For Support

Function of the lysosome
• Lysosomes keep the powerful hydrolytic enzymes separate from the rest of the cell.
Lysosomes can engulf old cell organelles and foreign matter, digest them and return the digested components to the cell for reuse.
8 of 13
Function of the cilia and undulipodia
• The epithelial cells lining your airways which have cilia that waft the mucus.
• Nearly all cell types in the body have one cilium that acts as an antenna. It contains receptors and allows the cell to detect signals about its immediate environment.

Function of the ribosomes
• Ribosomes bound to the exterior of RER are mainly for synthesising proteins that will be exported outside the cell.
Ribosomes that are free in the cytoplasm, either singly or in clusters, are primarily the site of assembly of proteins that will be used
10 of 13
Function of the centrioles
Before the cell divides,
the spindle fibres which pulls the chromosomes apart, form from the centrioles
11 of 13
Function of the cytoskeleton
Protein microfilaments within the cytoplasm give support and mechanical strength, keep cell's shape stable and allow cell movement
12 of 13
Function of the cell wall
• Provide strength and support
• Maintain the cell's shape
• Contribute to the strength and support of the whole plant
• Are permeable and allow solutions (solute and solvent) to pass through.
