2.3 & 2.5 Mitosis
2.3 & 2.5 Cellular Transport & Mitosis
| Term | Definition |
|---|---|
| active transport | the movement of materials through a cell membrane using energy |
| passive transport | movement of molecules across the cell membrane without the use of energy from the cell |
| diffusion | movement of molecules from an area of higher concentration to an area of lower concentration |
| cell membrane | semipermeable cell structure that controls which substances can enter or leave the cell |
| mitosis | cell division in which the nucleus divides into nuclei containing the same number of chromosomes |
| interphase | cell grows, performs its normal functions, and prepares for division; DNA replicates toward the end of this phase |
| prophase | first phase of mitosis, during which the DNA condenses into chromosomes and become visible. Nuclear membrane dissolves. Centrioles separate to opposite sides of the cell. |
| metaphase | phase of mitosis in which the chromosomes line up in the middle of the cell |
| anaphase | phase of mitosis in which the chromosomes separate and move to opposite ends of the cell |
| telophase | phase of mitosis in which the two new nuclei reform and chromosomes begin to unwind back into loose chromatin |
| cytokinesis | division of the cytoplasm to form two separate daughter cells |
