Science

6. a maze of passageways that processes substances including proteins and lipids
9. make proteins for the cell. Most float around in the cytoplasm
11. rod shaped organelles that convert energy from food to energy the cell can use
14. a thin flexible layer barrier that surrounds the cell and controls which substances pass into and out of the cell.
15. a clear gel like fluid that the organelles float around in.
16. the rigid outer layer that protects and supports the cell. It is made up of a strong material called cellulose.

1. some substances can cross the membrane while others cannot
2. when it does not require energy to move across the cell membrane
3. requires the cell to use energy to move across the cell membrane
4. structures inside the cell that help the cell function.
5. break down large particles into smaller ones
7. captures energy from the sun and converts it to energy
8. a form of passive transport in which the molecules move from an area of high concentration to an area of low concentration
10. stores food, water and wastes.
12. the basic unit of structure and function in living things
13. organelle that contains the cells genetic material in the form of DNA and controls the cells activities
