Leaves


We agreed that plants only need leaves to absorb sunlight and carbon dioxide for photosynthesis. They actually prevent water entering them, except from the roots via the stem and veins.


The key parts of the leaf cross-section that we were encouraged to talk about were: wax cuticle, palisade cells, air spaces, stoma, guard cells, and the spongy mesophyll.
