Cells - Life Science
| Definition | Term |
|---|---|
| A tiny unit in an organism that is said to be alive. | cell |
| The semipermeable coating of animal cells that holds in things inside the cell. | cell membrane |
| The stiff outer coating of plant, fungi and bacteria cells. | cell wall |
| The part of a plant cell that contains chlorophyll and in which photosynthesis occurs. | chloroplast |
| The jelly-like substance between the cell membrane and nucleus that contains the organelles and other cell bodies. | cytoplasm |
| The chemical found in cells that is the main component of chromosomes and carries genetic information. | DNA |
| The energy-producing organelle found in nearly all cells of plants and animals. | mitochondria |
| The central part of a cell which contains the genetic material, and is responsible for reproduction and synthesizing protein. | nucleus |
| A part of a cell that has a special function, much like an organ. | organelle |
| Tiny organelles that contain RNA and manufacture protein. | ribosome |
| An organism in which the genetic material inside of cells is contained within a distinct nucleus. | eukaryote |
| Consisting of many cells. | multicellular |
| A long, contractile cell that forms the muscles of the body. | muscle cell |
| An instrument used to magnify small objects. | compound light microscope |
| A process by which energy is released from food. | cellular respiration |
| A single celled organisms that do not contain distinct nuclear membranes around their genetic material. | prokaryote |
| A molecule that provides energy for cellular processes, | ATP, adenosine triphosphate |
| Unicellular organisms that contain cell walls and ribosomes but do not contain a nuclear membrane around their genetic material or other organelles common to plant and animal cells. | bacteria |
| Consisting of a single cell. | unicellular |
| The process by which light energy is used to combine water and carbon dioxide to produce glucose and oxygen. | photosynthesis |
| Folded membranes that process and move materials. | endoplasmic reticulum |
| Stores materials. | vacuoles |
| Breaks down food, waste and old cell parts. | lysosome |
| A cell organelle that helps process and package proteins and lipid molecules, destined to be exported from the cell. | golgi complex OR golgi apparatus |
| A physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. | diffusion |
