Across
- 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. the material or protoplasm within a living cell, excluding the nucleus.
- 5. the semipermeable membrane surrounding the cytoplasm of a cell.
- 7. in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
- 10. The endoplasmic reticulum is a type of organelle made up of two subunits – rough endoplasmic reticulum, and smooth endoplasmic reticulum
- 11. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
Down
- 1. powerhouse of the cell
- 3. 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.
- 6. the second stomach of a ruminant, having a honeycomb-like structure, receiving food from the rumen, and passing it to the omasum.
