| Question | Answer |
|---|---|
| Cytology | Study of cell |
| Cytosol | Intracellular fluid |
| Organelle | "little organs" structures that preform special functions for cell |
| Diffusion | Movement of materials from higher to lower concentration (even out) |
| Facilitated Diffusion | Diffusion with help of a protein channel |
| Passive Transport | No energy needed 1)Diffusion 2) Osmosis 3) Facilitated Diffusion |
| Active Transport | Used ATP energy |
| Osmosis | Diffusion of water to where there is more stuff (solute) |
| Hypotonic | Water moves in Cell swells Less stuff in water |
| Isotonic | Cell Maintains balance |
| Hypertonic | Water moves out Cell Shrivels More stuff in water |
| Hemolysis | Bursting red blood cells from being hypotonic |
| Phagocytosis | Cell eating (uses/needs energy) |
| Exocytosis | Sending materials out, exit (uses/needs energy) |
| Chromosomes | Coiled DNA 23 pairs |
| Gene | |
| Transcription | DNA is copied to make mRNA |
| Translation | Information from mRNA is used to make protein with help of tRNA |
| Messenger RNA | [mRNA] Copies |
| Transfer RNA | [tRNA] Moves |
| Somatic Cells | All cells in body aside from set cells |
| Apoptosis | Genetically programed cell death Cell suicide |
| Tumor | A mass of swelling made by abnormal cell growth and division |
| Cancer | Illness from effects of malignant cells |
| Microvilli | Surface projections increase surface area for absorption |
| Flagellum | Moves cells through fluid (sperm) |
| Cilia | Move fluids across cell surface (lungs, nose, thought) |
| Ribosomes | Proteins factories |
| Lysosomes | Cleaners (janitors) |
| Mitochondria | Energy Make ATP (power plant) |
| Nuclear Pores | Allows movement of materials in and out (not DNA) |
| Cell Theory | 1)Basic building blocks of all anilmals and plants 2)Smallest units of life 3)Products of cell division 4)Basic units homeostasis for the organism |
| Cell Membrane [Functions] | -Physical isolation -Regulation exchange of materials -Sensitive: receptors allow cell to recognize and respond to specific molecules in environment -Support |
| Selectively Permeable | Chooses what can pass through based on: -Size -Electrical Charge -Shape -Lipid Solubility |
