Across
- 3. highly condensed unit of DNA that exists during nuclear division
- 5. space within mitochondria where the krebs cycle takes place
- 6. folds of the inner membrane of mitochondria
- 9. stacks of thylakoids in the chloroplast where the light-dependent reactions of photosynthesis occur
- 11. includes the plasma membrane, nuclear envelope, smooth and rough ER, the Golgi apparatus,lysosomes,vesicles, and vacuoles
- 12. sac of hydrolytic enzymes in animal and some protist cells; breaks down ingested products, macromolecules, or damaged organelles
- 13. portion of the endoplasmic reticulum with ribosomes attached; aids in synthesis of proteins (abbreviated)
- 14. carry out cellular respiration by using oxygen to break down organic molecules and make ATP
- 15. network of microtubules, microfilaments, and intermediate filaments throughout the cytoplasm; mechanical,transport, and signaling functions
- 19. stacks of membranous sacs in eukaryotic cells that route and modify products of the ER
- 20. two layers of phospholipid molecules surrounding the cell; regulates materials that enter or exit the cell
- 21. complex of DNA and proteins that makes up eukaryotic chromosomes; loose and dispersed form when cell is not dividing
Down
- 1. structure in animal cells that is a microtubule-organizing center important for cell division
- 2. short microtubule appendages in eukaryotic cells; for locomotion or moving fluid past the cell
- 3. organelle in photosynthetic cells that absorbs sunlight to drive the synthesis of organic compounds from carbon dioxide and water
- 4. specialized structure in the nucleus where ribosomes are assembled
- 6. semifluid portion of the cytoplasm
- 7. liquid within chloroplasts where the light-independent reactions occur
- 8. made of rRNA and protein; site of protein synthesis; can be free in cytosol or bound to rough ER
- 10. pair of structures in the centrosome of an animal cell
- 15. large membranous sac in a mature plant cell with diverse roles in growth and storage of materials
- 16. portion of endoplasmic reticulum free of ribosomes; snythesis of lipids, detoxification (abbreviated)
- 17. long microtubule cellular appendages for locomotion
- 18. layer external to the plasma membrane in the cells of plants, prokaryotes, fungi, and some protists
