How are leaves adapted?
Leaves can be thought of as small ‘factories’ that produce
food for plants by photosynthesis.
Leaves are adapted so that
photosynthesis can take place.
Plants need carbon dioxide,
water, sunlight and chlorophyll to
carry out this important process.
What features of leaves make
them suitable for photosynthesis?

What are the useful features of leaves?
Leaves often have many features that make them suitable
for photosynthesis.
 A leaf is broad and flat to capture lots of sunlight.
 Veins carry water to the leaf and take food
from the leaf to the rest of the plant.
Veins also help to support the leaf.
 Certain plant cells contain
chloroplasts filled with
chlorophyll.
 Small holes called stomata
in the underside of a leaf
allow gases in and out.
