The Cell
Across
- 3. a lipid in which one fatty acid molecule is replaced by a molecule that contains a phosphate group
- 5. allows ions to pass through
- 11. helps move chromosomes during cell division
- 12. clusters of DNA, RNA, and proteins from the nucleus
- 13. concentration of solutes outside the cell leads water to leave the cell
- 16. Uses cellular respiration to produce ATP
- 17. molecule that carries energy inside the cell
- 18. where proteins and lipids are stored and modified for cells
- 21. holds secretion products
- 23. membrane-bound sac
- 24. large vacuole at the center of the plant cell with high concentration of solutes inside
- 25. diffusion
Down
- 1. allows nutrients to go in and out of cells
- 2. vesicle formed at plasma membrane to allow absorption of large molecules
- 4. deoxyribose nucleic acid
- 6. a highly porous membrane that separates nucleus from cytoplasm
- 7. control center of the cell, holds DNA
- 8. vacuole that holds the matter that engulfs a cell
- 9. carbs linked to proteins
- 10. requires ATP
- 14. holds animal cells together and helps maintain shape
- 15. a network of fibers that holds the cell together, keeps its shape, and aids in movement
- 19. process by which the cell engulfs foreign substances
- 20. stores waste
- 22. center of nucleus where RNA is made and ribosomes are assembled
