Across
- 2. composed of only one cell; prokaryotes are unicellular
- 10. the green pigment in chloroplasts that captures light energy for photosynthesis.
- 11. a rigid structure that surrounds the cell membrane of plant cells providing support and protection to the cell.; found in plants, fungi, and some bacteria.
- 13. a chemical compound that cells use for energy.
- 14. a cell with a membrane-bound nucleus and other membrane-bound organelles.
- 16. the flexible covering that surrounds a cell to provide protection.
- 18. an organelle where proteins are synthesized (created)
- 22. the organelle that modifies and packages proteins for specific uses in the cell.
- 23. studded with ribosomes. Provides surface area for chemical reactions to take place where newly made proteins are transported through its folds.
- 24. detoxifies the cell and synthesizes lipids.
- 27. a series of chemical reactions that changes the energy in food molecules to usable cellular energy.
Down
- 1. composed of more than one cell; all eukaryotes are multicellular
- 3. a network of protein fibers that helps the cell maintain its shape and assists with movement.
- 4. fluid, made mostly of water, that fills most of the space within a cell.
- 5. the process by which a cell divides into two new daughter cells, essential for growth and repair.
- 6. a basic unit of structure and function in all organisms; the smallest unit of matter that can carry on all the processes of life.
- 7. the control center of the cell, directs most cell activities; contains the cell’s hereditary information and controls the cell’s growth and reproduction.
- 8. a series of chemical reactions in some organisms that uses light energy and makes sugars.
- 9. a membrane bound sac used to store nutrients and wastes while helping in the digestive processes of the cell.
- 12. a structure inside a cell that carries out a specific process of life.
- 15. a type of cell division where a single cell divides to produce two identical daughter cells, crucial for growth and tissue repair.
- 17. an extensive network of membranes in a cell that acts like a highway along which molecules can move from one part of the cell to another.
- 19. a type of cell division that reduces the number of chromosomes by half, creating four haploid cells, essential for sexual reproduction.
- 20. the organelle that contains enzymes to break down or digest organic compounds and old organelles.
- 21. the cell structure responsible for changing energy from nutrients into a form that cells can use; the powerhouse of the cell
- 25. a cell organelle that uses light energy to make sugars from water and carbon dioxide and stores chlorophyll.
- 26. a cell that doesn't contain a membrane-bound nucleus or other organelle. Example: Bacteria
