Across
- 3. 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.
- 6. a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
- 9. a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane
- 12. the fluid that fills the cell, which includes the cytosol along with filaments, proteins, ions and macromolecular structures as well as the organelles suspended in the cytosol.
- 13. are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope.
Down
- 1. a short microscopic hairlike vibrating structure found in large numbers on the surface of certain cells, either causing currents in the surrounding fluid, or, in some protozoans and other small organisms, providing propulsion.
- 2. is a vital organelle in eukaryotic cells
- 4. a plastid in green plant cells which contains chlorophyll and in which photosynthesis takes place.
- 5. a slender threadlike structure, especially a microscopic appendage that enables many protozoa, bacteria, spermatozoa,
- 7. a small dense spherical structure in the nucleus of a cell during interphase.
- 8. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
- 10. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
- 11. a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells.
