TermDefinition
Cell membrane semipermeable membrane surrounding the cytoplasm of a cell
Cell wall a rigid layer of polysaccharides lying around the plasma membrane of plant cells
Cellular respiration a series of metabolic processes by which living cells produce energy by oxidizing organic substances
Chloroplast a cell organelle found only in plants used for carrying out photosynthesis
chromatin chromosomes are composed of this. It is made up of protein DNA and RNA
chromosome small x-shaped structure that carries genetic material in the form of genes
cristae a structure resembling a ridge or crest, such as that formed by folding of the inner membrane of a mitochondrion
cytoplasm the jelly like substance between the cell membrane and the nucleus. contains cytosol, organelles, cytoskeleton, and various particles.
cytoskeleton a shifting lattice arrangement of structural and contractile components distributed throughout the cell cytoplasm
Golgi bodies a membranous complex of vesicles, vacuoles, and flattened sacs in the cytoplasm of most cells: involved in intracellular secretion and transport
lysosome membrane-bound organelle in the cytoplasm cells containing hydrolytic enzymes that function in digestion.
matrix material in animal or plant cells, in which more specialized structures are embedded
mitochondria an organelle in the cytoplasm of cells that functions in energy production.
nuclear envelope the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells
nuclear pore a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm.
nucleolus a small rounded body within a resting nucleus that contains RNA and proteins and is involved in the production of ribosomes
nucleus a organelle found in most eukaryotic cells, a single rounded structure bounded by a double membrane, contains genetic material.
organelle any of a number of organized or specialized structures within a living cell
polysome a bunch of ribosomes held together by a strand of messenger RNA that each ribosome is translating.
ribosome organelle occurring in great numbers in the cell cytoplasm functioning as the site of protein manufacture.
rough endoplasmic reticulum Ribosomes are attached to the membrane of this organelle, making it “rough.”
smooth endoplasmic recticulum acts as a storage organelle. It is important in the creation and storage of lipids and steroids
vacuole These are storage bubbles found in cells. They might store food or any variety of nutrients a cell might need to survive.
vesicle cellular organelles that are composed of a lipid bilayer. These organelles are cellular envelopes that are used to transport materials from one place to another
