4. reticulum a network of passageways in which chemical compounds are manufactured, processed, and transported.
6. an organelle that converts the radiant energy of the Sun into chemical energy through the process of photosynthesis.
7. tiny structure where proteins are synthesized.
10. a small body in the nucleus where ribosomes are synthesized.
11. organelles that, using oxygen, convert nutrients into energy that can be used by the cell.
12. membrane a double-layered membrane that surrounds the nucleus.
13. a small sac, or vesicle, that contains digestive chemicals.
15. a type of vesicle that stores water, nutrients, and other chemicals. The large vacuole found in plant cells helps the cells maintain their shape.
16. a cell structure that performs a specific function.
17. apparatus a stack of membranes that collects, modifies, and packages chemical compounds.

1. – small, sac-like package of nutrients, proteins, or water created by the Golgi apparatus. Types of vesicles include vacuoles and lysosomes.
2. molecules, and other structures found in this region.
3. a double-layered membrane that surrounds the cell. Also called the plasma membrane, it regulates what enters and leaves the cell.
5. everything between the nuclear membrane and the cell membrane. The cytoplasm includes a jelly-like substance called cytosol along with all of the
8. a bundle of microtubules that helps organize the movement of chromosomes during cell division.
9. the rigid, porous outer layer of a plant cell.
10. a round body in the cell that contains DNA and regulates gene expression.
14. small structure that can store food (leucoplast) or pigment (chromoplast).
