| Active Transport | Transport process that requires an input of energy (ATP) to move a substance from an area of low concentration to an area of high concentration |
| Cell Cycle | The phases that a cell goes through as it divides |
| Cell Membrane | Membrane that surrounds the cell and regulates what enters and leaves the cell; also called the plasma membrane |
| Cell | Basic unit of life; the structural and functional unit of a living organism |
| Cytoplasm | Gel-like substance surrounded by the cell membrane but outside of the nucleus |
| Differentiate | Process whereby a cell becomes specialized |
| Diffusion | Passive transport process that causes movement of a substance from an area of higher concentration to an area of lower concentration |
| Endocytosis | Uptake of material through the cell membrane by forming a vesicle |
| Endoplasmic Reticulum | Intracellular membrane system concerned with the synthesis and transportation of protein |
| Equilibrium | Balance |
| Exocytosis | Elimination of material fron a cell through the formation of vesicles |
| Facilitated Diffusion | Passive process whereby a substance moves with the assistance of a carrier molecule from an area of higher concentration to an area of lower concentration |
| Filtration | Process whereby water and dissoled substances move through a membrane in response tp pressure |
| Golgi Apparatus | Membranous organelle concerned with the final trimming and packaging of protein for excytosis |
| Lysosomes | Organelle that contains powerful enzymes |
| Mitochondria | Organelles that produce most of the ATP |
| Mitosis | Type of cell division that produces two identical daughter cells, each containing 46 chromosomes |
| Nucleus | Large organelle separated from the cytoplasm by a nuclear membrane; stores the DNA in chromosomes and acts as the control center of the cell |
| Organelles | Part of the cell that performs a specialized function, such as the energy-producing mitochondrion |
| Osmosis | Movement of water across a membrane from an area where there is more water to an area where there is less water |
| Passive Transport | Transport process that requires no additional energy in the form of ATP |
| Ribosomes | Organelles concerned with the synthsis of protein |
