Across
- 3. grow
- 4. fake cells. don't have a nucleus. example: bacteria
- 6. gives shape and production. not found in animals cells
- 8. controls what gets in and out of the cell
- 9. doesn't have any ribosomes on it
- 10. creates and uses energy
- 11. sites of protein synthesis
- 12. when a substance travels from high to low concentration. molecules are bouncing off of each other
- 15. the smallest living thing. microscopic
- 16. packages and secretes the products of the cell
- 17. the molecules have to go through the gate, they can't get through the cell membrane
- 18. nucleus: control center. cell membrane: controls entry and exit of cell. ER: transportation, storage, works with golgi aparatus. vacuole: stores food, water, and wastes
- 20. cells are alive and are located in living things
- 21. the digestion center
- 23. when substances/particles from outside of the cell are captured by engulfing it with the cell membrane
- 25. direction of diffusion in terms of a membrane
- 27. just like endocytosis
- 28. something we keep at a certain level. example: body temperature (98.6)
- 29. control center of the cell. holds genetic information
- 31. a group of organs that work together to do many functions
Down
- 1. regular cells. have nuclei. example: humans in general
- 2. the "powerhouse" of the cell
- 5. makes photosynthesis. only found in plant cells
- 7. where does water move if an animal cell is placed in a beaker of pure water
- 13. what are the molecules doing on either side of a membrane when diffusion is "over" and concentration on either side is the same?
- 14. diffusion of water across the membrane
- 19. something that is made of cells. plants, animals, and humans are made of this
- 22. has ribosomes on it
- 24. structural framework
- 26. support and give shape
- 30. something made of tissues that are held in the body. each has a vital function
