Specialised Cells - project GCSE

Beneath the palisade mesophyll are the spongy mesophyll cells, which also perform photosynthesis.

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....

Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells....

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.

which allows carbon dioxide and oxygen to reach the palisade cells where they …

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.

Palisade Leaf Cells are adapted for photosynthesis: Thin: so more can be packed at the top of the leaf to get more light. Tall: more surface area for absorbing CO2
