When will the chloroplasts align with their flat surfaces parallel to the walls?

When will the chloroplasts align with their flat surfaces parallel to the walls?
  1. When they are perpendicular to the incident light
  2. When they get the optimum quantity of incident light
  3. When the mesophyll cells align them along the walls
  4. When they are directly light driven

Solution

The chloroplasts align themselves along the walls of the mesophyll cells so that they receive the optimum amount of incident light.
