Question

what is the relationship between structure and function in a leaf?
why?
what would the world be like without leaves—no grass for ball fields, no beautiful landscaping? it would also mean no oxygen for animals and no food for heterotrophs. leaves are like living machines that recycle the carbon and oxygen in our environment. this process, driven by the suns energy, allows for a constant supply of oxygen and food for the inhabitants of earth.
model 1 - leaf sun - catcher
general equation for photosynthesis
reactants
carbon dioxide + waterxrightarrowenergy{light}sugars + oxygen
