cell membrane, osmosis, diffusion, cellular respiration, photosynthsis, cells
| Question | Answer |
|---|---|
| How do you tell the difference between a leaf cell and a root cell? | The leaf cell has chloroplasts and is green |
| What organelle is not found in red blood cells but is found in white blood cells? | Nucleus |
| Why do you think that a red blood cell would not have this organelle? | so there's more room for gasses like oxygen and carbon dioxide |
| Diffusion is the movement of a substance from a region of what to what? | High concentration to low concentration |
| Only what molecules can move across the membrane | specific molecules |
| How do most water molecules diffusion across the membrane | Through an aquaporin |
| why is it difficult for water molecules to pass right through the membrane | because they are polar |
| why are some water molecules able to pass through directly | because water molecules are small and able to slip through |
