Cells and Organelles
Across
- 3. a cellular structure involved in the process of cell division.
- 7. produce proteins for the rest of the cell to function.
- 11. the ingestion of bacteria or other material by phagocytes and amoeboid protozoans.
- 12. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
- 14. an active, energy consuming process where extracellular fluid and solutes are taken up into a cell via small vesicles.
- 15. a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells.
- 17. 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.
Down
- 1. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 2. he membrane-enclosed organelle within a cell that contains the chromosomes.
- 4. the taking in of matter by a living cell by invagination of its membrane to form a vacuole.
- 5. any of a number of organized or specialized structures within a living cell.
- 6. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
- 8. a microscopic tubular structure present in numbers in the cytoplasm of cells, sometimes aggregating to form more complex structures.
- 9. small vesicles, single membrane-bound organelles found in the eukaryotic cells.
- 10. 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.
- 13. gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules.
- 15. he smallest, basic unit of life that is responsible for all of life's processes
- 16. the connective, functionally supportive framework of a biological cell, tissue, or organ.
