What is active transport | movement of molecules from low to high concentration that needs energy ATP |
How does diffusion help the cell? | movement of small particles through a cell membrane from high to low concentration |
How does osmosis happen? | movement of small particles in water through a cell membrane |
What is endocytosis? | the cell taking in larger particles |
What is exocytosis? | the cell removing larger particles |
How is the process of photosynthesis important to plants? | plants can make food |
