Cel Vocab
| Term | Definition |
|---|---|
| Cell | the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. |
| Cytoplasm | the gelatinous liquid that fills the inside of a cell |
| Tissue | any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products. |
| Microscope | an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times. |
| Mitochondria | membrane-bound cell organelle that generate most of the chemical energy needed to power the cell's biochemical |
| Organ | a collection of tissues that structurally form a functional unit specialized to perform a particular function. |
| Cell Theory | the cell is the fundamental structural and functional unit of living matter and that the organism is composed of autonomous cells with its properties being the sum of those of its cells. |
| Endoplasmic Reticulum | Image result for Endoplasmic Reticulum science definition A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. |
| Organ System | a group of organs that work together to perform bodily functions. |
| Cell Wall | a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose. |
| Golgi Apparatus | prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell. |
| Element | each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. |
| Cell Membrane | the semipermeable membrane surrounding the cytoplasm of a cell. |
| Chloroplast | a plastid that contains chlorophyll and in which photosynthesis takes place. |
| Compound | a thing that is composed of two or more separate elements; a mixture. |
| Nucleus | a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material. |
| Lysosome | an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane. |
| Lipid | any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids. |
| Organelle | a subcellular structure that has one or more specific jobs to perform in the cell |
| Multicellular | having or consisting of many cells. |
| Protein | any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues |
| Ribosome | a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins. |
| Unicellular | consisting of a single cell. |
| Enzyme | a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction. |
| Nucleic Acid | a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain. |
| DNA | a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. |
| Double Helix | a pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule. |
| Selectively Permeable | the property of a membrane that allows some substances to pass through but not others. |
| Passive Transport | movement of a solute from a region of high electrochemical potential on one side of the cell membrane to a region of lower electrochemical potential on the opposite side. |
| Diffusion | process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. |
| Osmosis | the transport of a solvent through a semipermeable membrane that separates two solutions of differing solute concentration. |
| Active Transport | moving against a gradient |
| Endocytosis | the process by which cells take in substances from outside of the cell by engulfing them in a vesicle |
