| phospholipid | has a polar head and nonpolar tails |
| hydrophilic | is a polar head of a phospholipid and its polar |
| hydrophobic | a non polar tails and its non polar |
| passive transport | does not use energy and makes materials with concentration gradient(high to low) |
| fluid mosaic model | amorphous substance that move freely past one another to assume the shape of the container and its either a liquid or gas |
| endocytosis | the process of cellular ingestion by plasma membrane that folds inward to bring substances into the cell |
| exocytosis | A process of cellular secretion or excretion in which substances contained in vesicles are discharged from the cell by fusion of the vesicular membrane with the outer cell membrane. |
