cells in action
Across
- 2. make proteins and contains DNA
- 3. the process by which a cell membrane surrounds the particle and encloses the particle in a vesicle to bring the particle into the cell .
- 4. is a group of tissues
- 6. is a part of the bacterium cell that helps the bacterium move .
- 8. is an organelle breaks down energy to make up ATP.
- 9. is the diffusion of water through a semipermeable
- 10. gives the process of photosynthesis .
- 11. is the when an organism breaks down dead organisms and waste
- 12. is the process in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane .
- 14. is the process by which plants use the sunlight and other nutrients to make food .
- 16. controls the cell and DNA
- 18. in the process by which cells use oxygen to produce energy from food.

Down
- 1. is the digestive system of an animal cell.
- 3. is the organelle that makes lipids , proteins and other materials
- 5. packages and distributes proteins and other nutrients to parts of the cell
- 7. is when a cell does not have a cell .
- 11. is the movement of particles from regions of higher density to regions of low density .
- 13. keeps the cell from collapsing
- 15. is the breakdown of food without the use of exygen .
- 17. stores oil , fiber and fat in the cell .
- 18. is the protector of the cell and controls the flow of nutrients and waste .
- 19. the movement of substance across a cell membrane without the use of energy by the cell
- 20. is a group of organs
- 26. is a prokaryotic cell that can live in extreme conditions
