Across
- 2. a ring cell structure that carries out a specific function within the cell
- 3. a thin, flexible barrier that surrounds the cell and controls which substances pass into and out of a cell
- 4. fills the region between the cell membrane and the nucleus
- 6. the basic unit of structure and function in living things
- 10. an instrument that makes small objects look larger
- 11. an organelle in the cells of plants and some organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food
- 13. is the diffusion of water molecules across a selectively permeable membrane
- 14. allows large particles to leave a cell
- 16. convert energy stored in food to energy the cell cab use to live and function
- 18. a process in which cells capture energy in sunlight and use it to make food
Down
- 1. the green photosynthetic pigment found in the chloroplast of plants, algae, and some bacteria
- 5. the process by which molecules move from an area with lighter concentration to an area of lower concentration
- 7. the cell membrane takes particles into the cell by changing shape and engulfing the particles
- 8. a sac like organelle that stores water, food, or other materials needed by the cell
- 9. producers that are able to create their own food in a form of glucose
- 12. an organism that cannot make its own food
- 15. two separate structures that are close together
- 17. a large oval organelle that contains the cells genetic material in the form of DNA and controls many of the cells activities
