Across
- 3. A green pigment that is present in most plant and algae cells and some bacteria, that gives plants their characteristic green color, and that absorbs light to provide energy for photosynthesis
- 4. A cell organelle composed of RNA and protein; the site of protein synthesis
- 7. A fiber found inside eukaryotic cells that is composed mainly of the protein actin and that has a role in cell structure and movement
- 8. A single-celled organism that does not have a nucleus or membrane-bound organelles
- 13. A membrane system found within chloroplasts that contain the components for photosynthesis
- 14. Present in plant cells. The rigid outer layer that helps keep plant structures shape
- 15. The soluble portion of the cytoplasm, which includes molecules and small particles, such as ribosomes
- 16. Hairlike structure arranged that projects from the surface of some cells
- 17. A group of similar cells that perform a similar function
- 18. Present in a plant cell. Stores water and waste.
- 19. A cell that contains a nucleus and membrane-bound organelles
- 20. This packages things to be moved around the cell
- 22. The theory that claims that all living things are made up of cells, that cells are the basic units of organisms, that each cell in a multicellular organism has a specific job, and that cells come only from existing cells
- 24. The cytoplasmic network of protein filaments that plays an essential role in cell movement, shape, and division
- 26. The double membrane that surrounds the nucleus of a eukaryotic cell
- 27. A group of organisms that perform similar tasks
- 28. One of the small, tubular fibers composed of the protein plays a role in cell structure and movement
- 29. Are responsible for the cleanup of the cell, and act as the janitor
Down
- 1. A double layer of phospholipids that makes up plasma and organelle membranes
- 2. Acts as the highway of the cell. Passageways that allow things to travel around the cell
- 5. The gel-like fluid in which all organisms settle
- 6. A collection of tissues that carry out a specialized function of the body
- 7. The powerhouse of the cell,produces energy for the cell
- 8. Present in plant cells that contain specific substances and perform specific functions for the cell
- 9. An organelle found in plant where photosynthesis occurs
- 10. One of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
- 11. A long, hairlike structure that grows out of a cell and enables the cell to move.Acts as a tail
- 12. Also known as the cell membrane, is the outer layer of a cell/semipermeable
- 15. An organelle that is active during mitosis
- 16. The smallest unit of life
- 21. Where the RNA is being made
- 23. Small bodies that are found in the cytoplasm of a cell and are specialized to perform a specific function
- 25. The control center of a cell
