Term | Definition |
---|---|
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 |
