Chemical equation for photosynthesis: Light energy
6CO2 + 6H2 O Chlorophyll
Tilted towards the sun to maximise light absorption.
Plant cells contain a green pigment called chlorophyll in the chloroplasts. This is essential for photosynthesis to occur.
Flat and thin so more light can be absorbed by the chloroplasts.
Tiny pores called stomata allow gases to move in and out. Mainly on the under-surface of the leaf.
Fig. 2 How leaves are adapted for photosynthesis.
Stomata allow gas exchange in the leaf. Carbon dioxide required for photosynthesis enters through the stomata. Oxygen produced during photosynthesis can exit from the leaf through the stomata. Water vapour also exits through the stomata. Carbon dioxide exits the stomata when the plant respires.
