The cell

3. genetic material
5. It stores and transport substances
7. A storage "sack" in the cytoplasm that holds food or wastes.
11. A type of plastid that performs photosynthesis.
12. A measure of disorder or randomness in a system.
15. Organisms that have more than one cell
17. lower the activation energy of reactions enough to allow them to occur safely in biological systems.
19. The theory that cells are the basic units of structure and function for all life.
21. Vesicles that contain enzymes to break stuff down, animal cells only.
22. A mode of transport that does not require the cell to use any energy.
23. The types of lipid which make up the cell membrane.
24. A cell organelle which manufactures the cells energy molecule, ATP.

1. requires the cell to use energy in order to move molecules across the membrane.
2. Organism that has only one cell.
4. The sticky layer that holds plant cells together.
6. A protective layer that surrounds the cell membrane.
8. a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
9. Organelles that make protein.
10. A series of tubes and membranes that store, modify, and package the products received from the ER. The Golgi also manufactures some proteins of its own.
11. A complex network of proteins that strengthen the cell and keep it from rupturing.
13. The barrier around all cells which protects them from the outside world.
14. The movement of molecules from an area of higher concentration to an area of lower concentration.
16. Stores DNA
18. A structure in the nucleus which assembles ribosomes
20. Jelly-like substance the cell organelles float in.
