Question 40

Which features adapt a palisade mesophyll cell for absorbing light? Select all that apply.

  1. It is separated from its neighbours by large air spaces
  2. It is packed with chloroplastsBonne réponse
  3. It is long and stands close beside its neighbours near the top of the leafBonne réponse
  4. It has a thick waxy wall that traps the light inside it

Explication

Light is caught by chloroplasts, so a cell that carries a great many of them and stands upright in the path of the light intercepts far more than a rounded, sparsely equipped cell would. Wide gaps between cells belong to the layer below, whose business is moving gases, and a thick waxy wall would keep light out rather than hold it in.
