Across
- 4. body a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 5. the central and most important part of an object, movement, or group, forming the basis for its activity and growth
- 7. how many parts are in the cell theory
- 9. the gelatinous liquid that fills the inside of a cell
- 10. organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae)
Down
- 1. it controls what goes in and out the cell
- 2. network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
- 3. minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
- 6. a plastid that contains chlorophyll and in which photosynthesis takes place.
- 8. walls rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.
