Across
- 3. a small dense spherical structure in the nucleus of a cell during interphase.
- 6. the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.
- 8. singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
- 9. Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.
- 10. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
- 12. Controls and regulates everything in
- 13. a membrane-bound cell organelle that contains digestive enzymes
Down
- 1. a 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.
- 2. a 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.
- 4. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 5. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
- 7. the semipermeable membrane surrounding the cytoplasm of a cell.
- 11. a 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.
