Characteristics of Life
|
1. uses energy
2. exchange with their environment (breathing, eating, wastes) 3. adapts to their environment/responds to stimuli 4. reproduces 5. grows 6. made up of cells 7. all have motion |

|
Movement of materials
|
Diffusion - the process by which molecules spread from an area of high concentration to an area of low concentration
Osmosis - same as diffusion but only in water and across a semi-permeable membrane Active Transport - when a cell uses energy to transport something |
