Question | Answer |
---|---|
Cell Membrane | the semipermeable membrane surrounding the cytoplasm of a cell. |
Cell Wall | 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. |
vacuole | a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid. |
chloroplast | (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place. |
mitochondria | an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae). |
endoplasmic reticulum | 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. |
nucleus | a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material. |
nucleolus | a small dense spherical structure in the nucleus of a cell during interphase. |
lysosome | an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane. |
cytoplasm | the material or protoplasm within a living cell, excluding the nucleus. |
ribosome | 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. |
