Review Plants-1

I placed this plant near the window. After two hours, I examined it. What would you expect to happen to the leaves during that time?

  1. The leaves will turn towards the light.

    Yes. The leaves will move and turn so that their surface gets as much light as possible. The following is a time lapse video, showing what happened with the plant.

  2. The leaves will turn away from the light.

    No. The leaves need light, so they turn to catch as much light as possible.
  3. The leaves will turn a darker green.

    No. While more light could eventually cause the leaves to grow and darken, the process would not happen in a couple of hours.
  4. The leaves will not change.

    No. Plants are adapted to turn their leaves towards a light source.
