Term | Definition |
Cell | the smallest structural and functional unit of an organism. {eukaryotic or prokaryotic]. |
Organelle | any of a number of organized or specialized structures within a living cell. |
Prokaryotic | A prokaryote is a unicellular organism that lacks a membrane-bound nucleus |
Eukaryotic | A eukaryote is any organism whose cells have a cell nucleus and other organelles enclosed within membranes. |
Multicellular | multicellular organisms are organisms that consist of more than one cell. |
Unicellular | A single cell. |
Biotic | Living. Plant and animals |
Abiotic | Non-Living, Pysical rather than biological. Sun, rocks, air |
Plasma membrane (Cell Membrane) The Gatekeeper | Membrane that surrounds a cell. It controls which substances move into and out of the cell |
Cell wall | a rigid layer surrounding the plasma membrane of the cells of plants, fungi, and bacteria. It provides support to a plant. |
Chloroplast | a plastid that contains chlorophyll and in which photosynthesis takes place. |
Mitochondria (Power Plant of the Cell) | an organelle found in large numbers in most cells.It converts food energy to energy used by the cell. |
Cytoplasm | Fluid material within a living cell. It fills most of the cell and allows organelles to move around in a cell. |
Lysosome | Organelle in the cytoplasm of eukaryotic cells. It breaks down food particles and worn-out cell parts. |
Nucleus | Control center of the cell. It directs cell activities |
Cell theory | 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. |
Tissue | tissue is a cellular organizational level intermediate between cells and a complete organ. |
Organ | a group of tissues in a living organism that have been adapted to perform a specific function. |
Organ system | an organ system is a group of organs that work together to perform one or more functions. |
Organism | An individual living thing that can react to stimuli, reproduce, grow, and maintain homeostasis. It can be a virus, bacterium, protist, fungus, plant or an animal. |
Homeostasis | The ability to maintain a constant internal environment in response to environmental changes. |
Rough Endoplasmic Reticulum (Rough ER) | Organelle that processes and transports proteins needed by the cell |
Smooth ER | Organelle that processes and transports substances other than proteins. It has no ribosomes. |
Golgi Apparatus (Cell Warehouse) | An organelle that packages and distributes proteins and materials from the ER and sends them to other parts of the cell |
Centrioles | |
Nucleoleus | |
Microtubules | |
Vesicles | |
Microvilli | |
DNA | the hereditary material in a cell that carries instructions for making proteins |
Central Vacuole | A large sac filled with water and makes a plant more rigid. It helps stand tall! |
Chloroplast | Plant organelle that makes food for cells using energy from the sun (photosynthesis) |
Ribosomes | Produce proteins needed by the cell |
