| Term | Definition |
|---|---|
| Diffusion | The process by which molecules move from an area of higher concentration to an area of lower concentration. |
| Osmosis | is the diffusion of water molecules through a selectively permeable membrane. (cell membrane |
| photosynthesis | The process by which a cell captures energy in sunlight and uses it to make food is called |
| Autotrophs | Organisms that manufacture their own food by Photosynthesis. (plants) |
| heterotrophs | Organisms that cannot make its own food, animals are called |
| Respiration | is the process by which cells obtain energy from glucose (sugar) |
| Mitochondria | powerhouses of cell. |
| cell cycle | The regular sequence of growth and division that cells undergo is known as the |
| daughter cells | During the cell cycle, a cell grows, prepares for division and divides into two new cells |
| Prophase | Chromatin in the nucleus condenses to form chromosomes Pairs of centrioles move to opposite sides of the nucleus Spindle fibers form a bridge between the ends of the cell The nuclear envelope breaks down |
| Metaphase | The chromosomes line up across the center of the spindle fiber apparatus Each chromosome attaches to the spindle fiber at its centromere. |
| Anaphase | The centromeres split The two chromatids separate, and each chromatid becomes a new chromosome. The new chromosomes move to opposite ends of the cell. The cell stretches out as the opposite ends are pushed apart. |
| Telophase | The chromosomes begin to stretch out and lose their rod like appearance. A new nuclear envelope forms around each region of chromosomes. |
| Cytokinesis | Cell membrane pinches around the middle of the cell The cell splits in two Each daughter cell ends up with an identical set of chromosomes and about half the organelles |
| prokaryotes | (bacteria) is one, circular chromosome attached to the inside of the cell membrane |
| chromatids | Duplicated chromosomes are called |
| Cell Cycle | G1 - primary growth phase S – synthesis; DNA replicated G2 - secondary growth phase collectively these 3 stages are called interphase M - mitosis C - cytokinesis |
| eukaryotic | cells store genetic information in chromosomes Most eukaryotes have between 10 and 50 chromosomes in their body cells Human body cells have 46 chromosomes or 23 identical pairs |
