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. a small cavity or space in tissue, especially in nervous tissue as the result of disease.
choloroplast (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 the central and most important part of an object, movement, or group, forming the basis for its activity and growth. "the nucleus of a film-producing industry" synonyms: core, center, central part, heart, nub, hub, middle, eye, focus, focal point, pivot
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.
