A scientist examines two adjacent membranes inside the chloroplast of an alga. The membranes are 120 nm120\ \text{nm}120 nm apart.
| Microscope | Resolution |
|---|---|
| light microscope | 200 nm200\ \text{nm}200 nm |
| transmission electron microscope | 0.2 nm0.2\ \text{nm}0.2 nm |
Explain which microscope the scientist should use to see the two membranes as separate structures and the effect of increasing the magnification if the light microscope were used instead.
