- 1Cytoplasm DefCytoplasm is the aqueous medium in which various organelles are suspended.
- 2Nucleus defNucleus contains blueprint for cell structure and function in the form of DNA
- 3Cell Membrane defPlasma membrane consists primarily of phospholipid molecules. Plasma membrane also includes proteins and carbohydrates
- 4Proteins in a cell membrane ex.ATPase, ion channels, hormone receptors

- 6Glycolipids defOligosaccharides bound to membrane lipids
- 7Endocytosis defbulk uptake of material through the plasma membrane
- 8Fluid-Phase pinocytosis defNon-specific endocytosis of fluid and molecules around cell. Enters cell by invagination and pinching off of cell membrane
- 9Fluid-Phase pinocytosis ex.macrophages, leukocytes, endothelial cells, microvilli of the intestine, kidney cells, epithelial cells of the intestine
- 10Receptor-mediated Endocytosis defSpecific endocytosis by target molecule binding to receptor. Invaginates and pinches off
