Across
- 3. the diffusion of water molecules across a selectively permeable membrane
- 4. cell membrane takes particles into the cell by changing shale and engulfing the particles
- 7. basic unit of structure and living things
- 9. clear,gel-like fluid
- 10. convert energy stored in food to energy the cell use to live and function
- 11. thin, flexible barrier that surrounds a cell and controls which substances pass into and out of a cell
- 12. tiny cell structure that carries out a specific function within the cell
- 13. organism that cannot make its own food; consumer
- 14. large oval organelle that contains the cell’s genetic material in the form of DNA and controls many of the cell’s activities
- 17. create their own food in the form of glucose
Down
- 1. allows large particles to leave a cell
- 2. the process by which molecules move from an area of higher concentration to an area of lower concentration
- 5. rigid surrounding layer that surrounds the cells of plants and some other organisms
- 6. permeable some substances can cross the membrane, while others cannot
- 8. widely accepted theory explanation of the relationship between cells and living things
- 9. green photosynthetic pigment found in the chloroplasts of plants, algae, and some bacteria
- 11. organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food
- 15. sac-like organelle that stores water, food, or other materials needed by the cell
- 16. cells capture energy in sunlight and use it make food in a process
