Plant Cell Organelles

2. form the internal membrane system in chloroplasts
5. sorting many of the cell's proteins and membrane constituents
7. support and suspend organelles and cellular molecules
8. keeps the contents of the nucleus
12. provides tensile strength and protection against mechanical and osmotic stress
14. separate and protect the intracellular environment from the extracellular space
15. help maintain water balance; control of cell volume and cell turgor
16. work to keep the vacuole acidic by bringing in protons
17. sole site of fatty acid β-oxidation
19. RNA synthesis and ribosome biogenesis

1. synthesizes lipids, phospholipids as in plasma membranes
3. provides mechanical support to the cell and its cytoplasmic constituents
4. produce proteins for the rest of the cell to function
6. store starch which will provide food for the plant
9. serve as cytoplasmic bridges to facilitate exchange of molecules between neighboring cells
10. allow plants to capture the energy of the Sun in energy-rich molecules
11. vesicles for delivery to targeted destinations
13. providing energy to carry out biochemical reactions and other cellular processes
18. synthesize proteins from amino acids
