- 7. this is where proteins are synthesised
- 9. root hair cells increase this
- 11. the process by which oxygen enters cells
- 12. in diffusion gases/liquids move from a high to low ...
- 14. increasing this speeds up the rate of diffusion
- 16. these are found in the head of a sperm cell
- 19. this is a feature of a plant cell but not an animal cell
- 20. this is where photosynthesis takes place
Down
- 1. this is the variable you measure
- 2. in a high concentration sugar solution potato ..... mass
- 3. this is what plant cell walls are made from
- 5. nerve cells carry these
- 6. root hair cells absorb this by osmosis
- 8. this is the variable you change
- 10. this describes a nerve cell
- 13. this is the structure that controls what enters/leaves the cell
- 15. this feature is present in both plant and bacterial cells
- 17. this is the variable you keep the same
- 18. muscle cells contain a lot of these to transfer energy
