Eukaryotic Cell Organelle Functions
by Kiara Jones
1. Rough ER - contains ribosomes and it is there for photo synthesis.
2. Smooth ER - lacks ribosomes. Synthesis of lipids.
3. Golgi apparatus - stacks of flattened vesicles. Packages proteins for export, forms secretory vesicles.
4. Vesicle - membrane-bound sac. Stores and transports substances.
5. Lysosome - contains hydrolytic digestive enzymes. Digests macromolecules and cell debris.
6. Peroxisome - contains oxidative and other enzymes and it also breaks down fatty acids.
7. Central Vacuole* - large membrane bound sac in plants. Storage compartment for water, sugars, ions and pigment.
8. Mitochondrion - bacteria-like element with double membrane. Carries out cellular respiration, produces ATP.
9. Cilia and flagella - Motility
10. Centrioles** - occur in pairs, composed of microtubules. Anchor and assemble microtubules.
11. Cell Wall *- contains cellulose or chitin and it is there for protection and support.
12. Plasma Membrane - lipid bilayer with embedded proteins and it relegates what goes in and out of the cell.
13. Nucleus - surrounded by a double membrane and contains chromosomes. Control centre of the cell and directs protein synthesis.
14. Nucleolus - site of genes for rNA synthesis and it assembles ribosomes.
15. Endoplasmic reticulum - network of internal membranes. Forms compartments and vesicles, synthesis and modification of proteins and lipids.
16. Chloroplast* - bacteria like element found in plants. The site for photosynthesis.
17. Cytoskeleton - network of protein filaments. Structural support, cell movement.
