| cells | All life forms are made up of |
| cell shape | what its function is |
| prokaryotes have | a simple loop of DNA |
| eukaryotic cells | can be single celled or multicelled |
| all eukaryotic cells have | a nucleus and membrane bound organelles |
| there are _____ parts to the cell theory | 3 |
| cytoskeleton is found in what type of cell? | both prokaryotes and eukaryotes |
| the nucleus stores the cells | DNA- "the brains" |
| ribosomes manufacture | proteins |
| where the golgi, ER & lysosomes are found | cytoplasm |
| chloroplasts are found in ______ cells | plant |
| mitochondria make | ATP- energy for the cell |
| differentiation | the process by which cells develop specialized forms and functions is called |
| colonial organism | cells that live in an connected group but do not depend on each other for survival (they could live independently) |
| organ system | A group of organs that work together to perform body functions. |
| organ | A collection of tissues that carry out a specialized function of the body. |
| tissue | A group of similar cells that perform a common function |
| pili | short thick outgrowths that allow prokaryotes to attach to surfaces or to other cells. |
| flagellum | long threadlike structures that rotate quickly to move an organism through its environment |
| central vacuole | a compartment in a plant cell that stores water, ions, nutrients and waste |
| lysosomes | A vesicle that contains enzymes that break down or digest large molecules |
| golgi apparatus | A set of flattened membrane bound sacs. products are modified and packaged for export |
| endoplasmic reticulum | A system of internal membranes that move proteins and other substances through the cell. sometimes has ribosomes attached. |
| vesicle | a small spherical sac formed by a membrane |
| ribosomes | Made of RNA and many proteins & found in all cell types this manufactures proteins |
| cytoskeleton | The skeleton of the cell |
| organelle | A structure that carries out specific activities inside of the cell. |
| thylakoid | A structure inside of the chloroplast that is involved in light reactions |
| nuclear pores | Holes in the nuclear membrane that allow certain things through |
| the cell theory | 1. all organisms are made of cells |
