Term | Definition |
Cells | smallest units of life |
Cell Membrane | the outer protective covering of the cell |
Centrosome | the centriole containing region of clear cytoplasm adjacent to the cell nucleus |
Chomatin | a complex of a nucleic acid with basic proteins in eukaryotic cells that is usually dispersed in the interphase nucleus and condensed into chromosomes in mitosis and meiosis |
Cytoplasm | the material or protoplasm within a living cell, excluding the nucleus |
Cytokinesis | the division of the cytoplasm of a plant or animal cell into two |
Endoplasmic reticulum | network of interconnected structures that function especially in the transport of materials within the cell |
Genes | the structures that carry inherited characteristics |
Genome | a total set of chromosomes with the genes they contain, consisting of strings of DNA Nucleotides |
Golgi Apparatus | a cytoplasmic organelle that consists of a stack of smooth membranous saccules and associated vesicles and that is active in the modification and transport of proteins |
Glycolysis | the breakdown of glucose inside the cell |
Lysosomes | a saclike cellular organelle that contains various digestive enzymes |
Meiosis | form of cellular reproduction specific to sex cells in all sexually reproducing single celled and multicelled eukaryotes |
mitochrondria | found outside the nucleus, responsible for producing energy for the cell through the breakdown of carbohydrates, proteins and fats |
Mitosis | form of cellular reproduction that occurs in the nucleus of a dividing cell resulting in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus |
nucleolus | located inside the nucleus, responsible for the production of ribosomes |
nucleus | a mass located in the cytoplasm of a cell, separated from the cytoplasm by a nuclear membrane, considered the control center |
organ | a differentiated structure consisting of cells and tissues performing some specific function in an organism |
organelles | a specialized cellular part that is analogous to an organ |
pinocytic vesicles | pocketlike folds located in the cell membrane allowing the entrance and storage of large molecules such as proteins and fats |
tissues | an aggregate of cells usually of a particular kind together with their intercellular substance that form one of the structural materials of a plant of an animal that that in animals include connective tissue, epithelium, nerve tissue and muscle tissue |
protoplasm | the basic substance of all life; this substance forms the cell |
stem cells | an unspecialized cell that gives rise to differentiated cells |
system | a group of body organs or structures that together perform one or more vital functions |
vacuoles | pouchlike storage structures located throughout the cytoplasm |
hypertrophy | cells enlarge caused by an increase of proteins in the cell membrane and cell structures, not an increase in the cell's fluid |
hyperplasia | the number of cells increase; there is an increased rate of cell division |
dysplasia | the size, shape or organization of mature cells becomes abnormal |
neoplasia | the formation of tumors, either cancerous or noncancerous |
cell cycle | the series of events involving the growth, replication and division of an eukaryotic cell |
