Question | Answer |
---|---|
Semipermeable | Allows certain substances to cross over a membrane. |
Permeable | Allows all substances to cross over a membrane. |
Photosynthesis | The process a plant uses to gain energy: Water + Sun + Carbon Dioxide = Oxygen and Energy |
Glucose | Simple sugar (C6H12O6) |
Cellular Respiration | The process that animals use to gain energy: Oxygen + Food (glucose) = Carbon Dioxide, Water, and APT (Energy) |
Mitochondria | The organelle that makes the energy for the cell- The place where cellular respiration occurs. |
Chloroplast | The organelle in a plant cell where photosynthesis occurs. |
Fermentation | The lack of oxygen when energy is being used. |
Diffusion | Movement of substances from high to low (membrane or no membrane) |
Osmosis | Movement of WATER from high to low with a semipermeable membrane. |
Passive Transport | Does NOT use energy when bringing substances into a cell. |
Active Transport | Uses energy to bringing substances into a cell. |
Endocytosis | Surrounds a particle or substance and forms a vesicle to bring into the cell. |
Exocytosis | Releasing substances or particles from the cell. |
DNA | Controls the cells activities. |
Chromosomes | Where your DNA is organized. |
Mitosis | Process where a single cell divides twice to produce two identical daughter cells. |
Meiosis | Process where a single cell divides to produce four cells with 1/2 the original genetic info. Sex Cells. |
Interphase | Phase 1- Chromosomes are copied. |
Prophase | Phase 2- Nuclear membrane dissolves and starts to move to opposite poles, nucleus begins to disappear. |
Metaphase | Phase 3- Chromosomes are lined up, homologous or save chromosomes pair up, centrioles are on opposite poles. |
Anaphase | Phase 4- Chromatids separate and move to opposite sides of the cell. |
Telophase | Phase 5- Nuclear membrane reforms, cytokinesis starts. |
Cytokinesis | The separating of two cytoplasm's to make two cells. |
