On meeting which one does a leucoplast turn into a chloroplast?
Think it through first, then pick an option.
- a Soil
- b Light
- c Air
- d Water
Answer and explanation
Correct answer: b Light
On meeting light a leucoplast can change into a chloroplast.
Why the other options are wrong
- a Soil: Soil gives no light; a leucoplast under the soil stays a leucoplast.
- c Air: Air alone does not bring about this change; light is needed.
- d Water: Water alone does not bring about this change; light is needed.
