| cell membrane | selectively regulates the materials moving to and from the cell; |
| cell | the simplest level of organization |
| tissue | a group of cells with a similar function |
| organs | groups of tissues working together to perform a common function are called organs.ex the nervous, muscle, and other tissues which make up the heart; |
| system or organ system | groups of organs working together to perform a common function |
| food vacuole | stores and digests food |
| contractile vacuole | contractilpumps out wastes and excess water from the cell |
| chloroplast | found in plant cells and algae ;carries on photosynthesis |
| cell wall | surrounds and supports plant cells |
| cell membrane | functions include separation of the cell from its outside environmentcontrolling which molecules enter and leave the cell |
| Diffusion/ passive transport | Diffmovement of materials from a region of higher to a region of lower substance concentration |
| Active transport | molecules move from a region of lower concentration to a region of higher concentration, the cell has to use energy in the form of ATP to make active transport occur |
| Lipids (fats) | yields a digestive product of fatty acids and glycerol; |
| Proteins | yields a digestive product of amino acids |
| Carbohydrates | yields a digestive product of simple sugars (glucose |
