Cells/Organelles/Transport
| Term | Definition |
|---|---|
| Prokaryote | Bacteria cell, lacks organelles, has ribosomes, always unicellular, smallest type of cell, oldest cell |
| Eukaryote | Plant/Animal Cells, has organelles, has nucleus, can be multicellular or unicellular |
| Semi-permeable | allows some material in, while blocking other material |
| passive transport | does not use energy |
| active transport | uses energy |
| mitochondria | Transform chemical energy (sugar) into useful energy (ATP) |
| chloroplast | captures sunlight and converts it into chemical energy (sugar) |
| flagella | long whip-like projection used for movement |
| cilia | hair like structure found on eukaryotic cells |
| nucleus | directs the activities within the cell |
| nucleolus | makes ribosomes and contains chromatin |
| cell wall | rigid wall outside plasma membrane giving extra support to plant cells |
| vacuole | sac-like structure used for storage |
| ribosomes | makes proteins |
| contractile vacuole | removes excess water to maintain homeostasis |
| pseudopod | false foot; used for engulfing material |
| eye spot | detects sunlight |
| Two types of transport | active and passive |
| Three types of passive transport | diffusion, osmosis, and facilitated diffusion |
| Two types of active transport | endocytosis and exosytosis |
| a cell membrane is made up of ____________ | phospholipids |
| getting rid of toxins allows the cell to maintain _____________ | homeostasis |
| cell differentiation | cells become specialized |
| phototaxis | movement to or away from light |
| chemotaxis | movement to or away from chemicals |
| plasmids | found in prokaryotes; extra chromosome that holds important information |
| organelle | little organ |
| equilibrium | equal or balanced |
| Three types of osmosis | hypotonic, isotonic, hypertonic |
| hypotonic | the cell swells |
| isotonic | the environment and cell maintain an equilibrium |
| hypertonic | the cell shinks |
