| Question | Answer |
|---|---|
| Prokaryote | any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops |
| Eukaryote | any organism having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes |
| Unicellular | having or consisting of a single cell |
| Multicellular | composed of several or many cells |
| Cell Theory | a basic tenet of modern biology, first stated by Matthias Schleiden and Theodor Schwann in 1838–39, that cells are the basic units of structure and function in living organisms. |
| Cell Wall | the definite boundary or wall that is part of the outer structure of certain cells, as a plant cell. |
| Cell Membrane | the semipermeable membrane enclosing the cytoplasm of a cell. |
| Organelle | a specialized part of a cell having some specific function; a cell organ |
| Cytoplasm | the cell substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles |
| Nucleus | a specialized, usually spherical mass of protoplasm encased in a double membrane, and found in most living eukaryotic cells, directing their growth, metabolism, and reproduction, and functioning in the transmission of genic characters. |
| Nucleolus | a conspicuous, rounded body within the nucleus of a cell which creates ribosomes |
| Mitochondria | an organelle in the cytoplasm of cells that functions in energy production |
| Vacuole | a membrane-bound cavity within a cell, often containing a watery liquid or secretion under cell. |
| Chloroplast | a plastid containing chlorophyll |
| 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 |
| Smooth ER | a network of tubular membranes within the cytoplasm of the cell |
| Rough ER | a network of tubular membranes within the cytoplasm of the cell |
| Golgi Body | studded with ribosomes involved in the transport of materials. |
| Lysosome | a cell organelle containing enzymes that digest particles and that disintegrate the cell after its death |
| Turgor Pressure | Also called: hydrostatic pressure the pressure exerted on a plant cell wall by water passing into the cell by osmosis |
| Endocrine System | The bodily system that consists of the endocrine glands and the hormones that they secrete. |
| Immune System | Fights of diseases with white blood cells |
| Lymphatic System | System of vessels which help the veins retain water |
| Homozygous | pure breed, of the same alleles |
| Heterozygous | hybrid, different allels |
