Leaves: Function • Photosynthesis - leaves use light energy, carbon dioxide and water to make carbohydrates. B. Gas & Water Exchange - plants have stomata that open or close for gas and water exchange with the environment. Stomata
Leaves: Adaptations Simple Leaf Thick Cuticle Compound Leaf Pine Needles Thin Cuticle
Diversity of Plants How will you design your Plant? What role does the environment have on plant adaptations?
