Photosynthesis - perfect chemistry in Nature
For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....
Photosynthesis: Photosynthesis means “making with light”
This does not hinder carbon dioxide
diffusion enough for the supply of carbon dioxide to be aversely affected, and light can reflect of the cylindrical
palisade cells deeper into the leaf, so the spongy mesophyll still receive adequate light.
It is the chlorophyll that taps the light energy and converts
it into chemical energy to make food, fuel and chemical building blocks for the plant.
The palisade mesophyll cells are column or plate-like and all arranged in a close array with their
chloroplasts aligned and stacked in such a way as to intercept as much light as possible.
