|
What is the difference between a plant and animal cell? |
Plant cells has a cellulose cell wall, and a large permanent vacuole instead of multiple small temporary ones. Also palisade mesophyll and chloroplasts |
|
|
Cellulose Cell Wall (plants) |
Provide structure, support and protection |
|
|
Chloroplasts |
Photosynthesis |
|
|
Cytoplasm |
Fluid in which organelles float |
|
|
Diffusion |
Met movement of particles from a region of higher concentration down a concentration gradient as a result of their random movement |
|
|
How do substances move in and out of cells? |
Through diffusion |
|
|
How does water diffuse through partially permeable membranes? |
Through osmosis |
|
|
osmosis |
Net movement of water molecules from a region of higher water potential to lower water potential through a partially permeable membrane |
|
|
Factors that influence diffusion |
Surface area, temperature, concentration gradient, diffusion distance |
