Biology Vocab 5.1
Across
- 3. organisms an organism that consists of only one cell
- 5. protects the cell
- 6. single cells take on specific tasks, such as reproducing, moving the colony, and removing wastes, but individual cells can break away from the colony and function on their own
- 8. line up amino acid to make proteins
- 10. Organism organism with more than one cell
- 12. vacuole stores water, starch, and pigments in plant cells
- 15. Control center of the cell
- 17. builds parts for the cytoskeleton
- 19. little organs
- 21. An organism whose cells lack a nucleus and some other cell structures
- 22. system group of organs that work together to perform a specific function
- 24. extensions of the cytoskeleton
- 25. membrane A cell structure that controls which substances can enter or leave the cell.
- 26. Clusters of DNA, RNA, and proteins in the nucleus of a cell
- 27. An organelle containing digestive enzymes
- 28. bilayer gives cell membranes a flexible structure that forms a strong barrier between the cell and its surroundings
Down
- 1. A long, hairlike structure that grows out of a cell and enables the cell to move.
- 2. An organism whose cells contain a nucleus
- 4. Found inside the nucleus and produces ribosomes
- 7. an assembly of similar cells
- 9. Different tissues that work together to perform a specific function
- 11. An organelle found in plant and algae cells where photosynthesis occurs
- 12. network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement
- 13. wall strong, supporting layer around the cell membrane in some cells
- 14. Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
- 16. Endoplasmic Reticulum Transports compounds around the cell and helps maintain the cell's shape; processes fats and breaks down toxic substances in liver cells.
- 17. theory idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
- 18. A stack of thylakoids in a chloroplast
- 20. apparatus a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 23. found in prokaryotes; contains the genetic material for the cell; floats freely in the cytosol
- 24. A jellylike fluid inside the cell in which the organelles are suspended
