|---|---|
| The movement of substance through a cell membrane only by using the cells energy | Active Transport |
| A flexible covering that protects the inside of a cell from the environment outside the cell | Cell membrane |
| A series of chemical reactions that convert the energy in food molecules into a usable form of energy | Cellular Respiration |
| The fluid or liquid part of a cell membrane that contains salt and other molecules. | Cytoplasm |
| The movement of substance from an area of higher concentration to an area of lower concentration | Diffusion |
| The process during which a cell takes in a substance by surrounding the cell membrane | Endocytosis |
| Process during which the cell's visicles release their contents outside the c3ell | Exocytosis |
| The process by which molecules are too large to travel through using diffusion so they use special proteins called transport proteins | Facilitated diffusion |
| A reaction that eukaryotic and prokaryotic cell can use to obtain energy from food when oxygen levels are low | Fermentation |
| A process by which glucose, a sugar, is broken down into smaller molecules | Glycolysis |
| The movement of substance through the cell membrane without the cells energy | Passive Transport |
| A series of chemical reactions that convert light energy, water, and CO2 into the food energy molecule glucose and give off oxygen | Photosynthesis |
| The diffusion of water molecules only through a membrane. | Osmosis |
