All 12 Organelles
| Term | Definition |
|---|---|
| Unicellular | Having or consisting of a single cell. |
| Multicellular | Composed of several or many cells. |
| Prokaryotic Cell | any cellular organism that has no nucleus, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera. |
| Mitosis | the usual method of cell division. (when DNA is copied) |
| Binary fission | fission into two organisms approximately equal in size. |
| Homeostasis | the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function. |
| 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 one or more functions. Each does a particular job in the body, and is made up of certain tissues. |
| organism | Any living thing |
| golgi bodies/ complex | Lipids and proteins from the ER are delivered here where they are modified for different functions, "packaged" then pinched |
| cell wall | A hard wall in plant cells that provide strength and support. |
| lysosome | These are special vesicles that contain enzymes that destroy worn-out or damaged organelles, they get rid of waste materials & protect the cell from foreign invaders. |
| chloroplast | An additional energy converting organelle in plant cells and algae, contains chlorophyll, photosynthesis happens here. |
| Endoplasmic Reticulum (E.R.) | A membrane covered compartment that makes lipids and other materials for use inside and outside the cell, breaks down drugs and certain chemicals, also considered the internal delivery system. |
| Ribosome | These are found on the ER or floating around in the cell, they make proteins that cells must have, each cell contains thousands. |
| Cytoskeleton | A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement |
| Eukaryotic Cell | A type of cell with a membrane-enclosed nucleus and membrane-enclosed organelles. Examples are(protists, plants, fungi, and animals). |
| Cell | The basic unit of life. |
