Across
- 6. structures that bud off from the cell membrane-enclosed organelles
- 8. complex structures made of many protein and RNA molecules and build proteins.
- 9. a type of cell that has no membrane-bound organelles or nucleus
- 11. large, fluid-filled vesicles that store or break down waste, debris, toxins, or food.
- 13. a membrane-bound structure that break down and recycle macromolecules and cellular debris, repair the cell membrane, and process foreign particles such as bacteria and viruses
- 14. a component of the cytoskeleton that is made up of tube-shaped subunits which gives them the ability to participate in mitosis
- 16. a type of cell that contains a nucleus and membrane-bound organelles
- 18. a structure found in plant cells and some protists, that carry out the reactions of photosynthesis
- 19. (two words, no space between words) a component the cytoskeleton that structurally support cell membranes and tissues and are the most stable part of the cytoskeleton
- 21. (two words, no space between the words)a structure that encloses the cell membrane of most prokaryotic, plant, fungal, and protist cells
- 22. (two words, no space between words) a system of sacs and tubes that make up this structure, which extends out from nuclear membrane
Down
- 1. a structure made up of a system of interconnected protein filaments that reinforces, organizes, and moves cells
- 2. (two words, no space between the words) a folded membrane that looks like a stack of pancakes, and functions by altering proteins that have been delivered from the endoplasmic reticulum
- 3. single-celled microorganisms with a structure similar to bacteria that live in extreme environments, with low oxygen
- 4. a component of the cytoskeleton that reinforces cell membranes, and functions in muscle contractions
- 5. structures that carry out special functions inside a cell, and usually are surrounded by at least one plasma membrane
- 7. simple eukaryotic organisms that are neither plants nor animals or fungi.
- 10. (two words, no space between the two words)a lipid bilayer that separates the cell from the external environment and controls exchanges between the cell and its environment
- 12. a part of the nucleus where ribosomes are synthesized
- 15. a specialized structure that is used carry out the reactions of aerobic cellular respiration
- 17. a jelly-like mixture of water, sugar, ions, and proteins that is found between the cell membrane and the nucleus in eukaryotic cells
- 20. a membrane-bound organelle that contains the DNA of an eukaryotic cell
