Eukaryotic Cell Organelle Functions by Mind Map: Eukaryotic Cell Organelle Functions

1. Cell Wall *- contains cellulose or chitin and it is there for protection and support.

2. Plasma Membrane - lipid bilayer with embedded proteins and it relegates what goes in and out of the cell.

3. Nucleus - surrounded by a double membrane and contains chromosomes. Control centre of the cell and directs protein synthesis.

4. Nucleolus - site of genes for rNA synthesis and it assembles ribosomes.

5. Endoplasmic reticulum - network of internal membranes. Forms compartments and vesicles, synthesis and modification of proteins and lipids.

6. Rough ER - contains ribosomes and it is there for photo synthesis.

7. Smooth ER - lacks ribosomes. Synthesis of lipids.

8. Golgi apparatus - stacks of flattened vesicles. Packages proteins for export, forms secretory vesicles.

9. Vesicle - membrane-bound sac. Stores and transports substances.

10. Lysosome - contains hydrolytic digestive enzymes. Digests macromolecules and cell debris.

11. Peroxisome - contains oxidative and other enzymes and it also breaks down fatty acids.

12. Central Vacuole* - large membrane bound sac in plants. Storage compartment for water, sugars, ions and pigment.

13. Mitochondrion - bacteria-like element with double membrane. Carries out cellular respiration, produces ATP.

14. Chloroplast* - bacteria like element found in plants. The site for photosynthesis.

15. Cytoskeleton - network of protein filaments. Structural support, cell movement.

16. Cilia and flagella - Motility

17. Centrioles** - occur in pairs, composed of microtubules. Anchor and assemble microtubules.
