| Question | Answer |
|---|---|
| Cell | A collection of living matter enclosed by a barrier that separates the cell from its surroundings; basic unit of all forms of life |
| Cell theory | The therory that all living things are composed of cells, and cells are the basic units of all life. |
| Nucleus | The center of an atom |
| Eukaryote | Organism who's cell contains nuclei |
| Prokaryote | Unicellular organism lacking of nucleus |
| Organelle Cytoplasm | the cell substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles. |
| Nuclear Envelope | the double membrane surrounding the nucleus within a cell. |
| Chromatin | the readily stainable substance of a cell nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division. |
| Chromosome | any of several threadlike bodies, consisting of chromatin, that carry the genes in a linear order: the human species has 23 pairs, designated 1 to 22 in order of decreasing size and X and Y for the female and male sex chromosomes respectively. |
| Nucleolus | a conspicuous, rounded body within the nucleus of a cell |
| ribosome | a tiny, somewhat mitten-shaped organelle occurring in great numbers in the cell cytoplasm either freely, in small clusters, or attached to the outer surfaces of endoplasmic reticula, and functioning as the site of protein manufacture. |
| Endoplasmic reticulum | a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum), involved in the transport of materials. |
| lyossome | a cell organelle containing enzymes that digest particles and that disintegrate the cell after its death |
| mitochondrion | an organelle in the cytoplasm of cells that functions in energy production. |
| golgi apparatus | an organelle, consisting of layers of flattened sacs |
| vacuole | a membrane-bound cavity within a cell, often containing a watery liquid or secretion. |
| chloroplast | a plastid containing chlorophyll. |
| Cytoskeleton | a shifting lattice arrangement of structural and contractile components distributed throughout the cell cytoplasm, composed of microtubules, microfilaments, and larger filaments, functioning as a structural support and transport mechanism. |
| Centriole | a small, cylindrical cell organelle, seen near the nucleus in the cytoplasm of most eukaryotic cells, |
| cell membrane | the semipermeable membrane enclosing the cytoplasm of a cell. |
| Cell wall | the definite boundary or wall that is part of the outer structure of certain cells, as a plant cell. |
| lipid bilayer | phospholipid bilayer. |
| Concentration | a mass of solute in a given volume of solution, or mass/volume. |
| diffusion | Also called migration. an intermingling of molecules, ions, etc., resulting from random thermal agitation, as in the dispersion of a vapor in air. |
| equilibrium | a state of rest or balance due to the equal action of opposing forces. |
| osmosis | the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane. |
| isotonic | Also, isosmotic. Physical Chemistry . noting or pertaining to solutions characterized by equal osmotic pressure. |
| hypotonic | noting a solution of lower osmotic pressure than another solution with which it is compared |
| endocytosis | the transport of solid matter or liquid into a cell by means of a coated vacuole or vesicle |
| pinocytosis | the transport of fluid into a cell by means of local infoldings by the cell membrane so that a tiny vesicle or sac forms around each droplet, which is then taken into the interior of the cytoplasm. |
| Hypertonic | noting a solution of higher osmotic pressure than another solution with which it is compared |
| exocytosis | the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane |
| phagocytosis | the ingestion of a smaller cell or cell fragment, a microorganism, or foreign particles by means of the local infolding of a cell's membrane |
| facilitated diffusion | a process by which substances are transported across cell membranes by means of protein carrier molecules; also called facilitated transport |
| active transport | the movement of ions or molecules across a cellular membrane from a lower to a higher concentration, requiring the consumption of energy. |
| Cell specialization | Cell specialization is when a group of cells work together by performing individual tasks for large organs and tissues. |
| Tissue | an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism. |
| Organ | a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task. |
| Organ System | A group of organs that work together to perform a specofoc function |
