Question | Answer |
cell cycle | the life cycle of a cell |
exocytosis | the process in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane |
active transport | the movement of substances across the cell membrane that requires the cell to use energy |
passive transport | the movement of substances across a cell membrane without the use of energy by the cell |
osmosis | the diffusion of water through a semipermeable membrane |
diffusion | the movement of particles from regions of higher density to regions of low density |
chromosomes | in eukaryotic cells one of the structures in the nucleus that are made up of DNA and protein: in prokaryotic the main ring of DNA |
homologous chromosomes | chromosomes that have the same sequence of genes and the same structure |
mitosis | in eukaryotic cells a process of cell division that forms two new nuclei each of which has the same number of chromosomes |
cytokinesis | the division of the cytoplasm of a cell |
interphase | before mitosis begins chromosomes are copied |
prophase | mitosis begins. chromosomes condense from long strands into rodlike structures |
metaphase | the nuclear membrane is dissolved. paired chromatids align at the cells equator |
anaphase | chromatids separate and move to opposite sides of the cell |
telophase | a nuclear membrane forms around each set of chromosomes and the chromosomes unwind. mitosis is complete |
vesicle | sacs formed from pieces of cell membrane |
