| A | B |
|---|
| selective permeability | ability to choose what is allowed in and out and (examples: cell membrane and gortex) |
| open system | needs input and outputs of matter and energy to exist AND function (examples: a bike) |
| regulatory system | has subsystems that work together to maintain homeostasis (examples: radiator in your car stops overheating) |
| homeostasis | a self adjusting balance (example: cell in a isotonic situation) |
| active transport | requires cell's energy to move things in and out across membrane (example: bulk endocytosi, exocytosis and carrier) |
| passive transport | DOESN'T require the cell's energy to move things in and out across the membrance (example: osmosis and diffusion) |
| define "system" (2) | a group of parts or events which 1) interact with and 2) are interdependent |
| isotonic | both directions |
| hypertonic | out of the cell SUPER FAST HYPER |
| hypotonic | into the cell |
