  1. 4. an organelle near the nucleus of a cell which contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division.
  2. 6. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
  3. 7. any of a number of organized or specialized structures within a living cell.
  4. 10. a process by which the cell takes in the fluids along with dissolved small molecules
  5. 11. the ingestion of bacteria or other material by phagocytes and amoeboid protozoans.
  6. 12. small vesicles, single membrane-bound organelles found in the eukaryotic cells
  7. 13. A cell is the smallest unit that is typically considered alive and is a fundamental unit of life
  8. 15. a microscopic tubular structure present in numbers in the cytoplasm of cells, sometimes aggregating to form more complex structures.
  9. 17. the taking in of matter by a living cell by invagination of its membrane to form a vacuole.
  10. 18. the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
  11. 20. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.

  1. 1. the material or protoplasm within a living cell, excluding the nucleus.
  2. 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.
  3. 3. the connective, functionally supportive framework of a biological cell, tissue, or organ
  4. 5. 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.
  5. 8. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
  6. 9. a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
  7. 14. the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
  8. 16. a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
  9. 19. to produce proteins for the rest of the cell to function
