Which part of the chloroplast captures sunlight?
Think it through first, then pick an option.
- a Outer membrane
- b Stroma lamella
- c Stroma
- d Grana
Answer and explanation
Correct answer: d Grana
The grana trap sunlight and turn it into chemical energy.
Why the other options are wrong
- a Outer membrane: The outer membrane is only an envelope and does not trap light.
- b Stroma lamella: Stroma lamellae join the grana; it is the grana that capture light.
- c Stroma: The stroma holds the enzymes and builds the sugar; light is not trapped there.
