Plants make their own food by a process called photosynthesis.
The plants take in carbon dioxide and turn it into sugar, releasing oxygen as a waste product.The process needs the energy from the sunlight (light energy) and this is then trapped by the green pigment in the leaves called chlorophyll.
carbon dioxide + water ---(light energy)---> glucose + oxygen
photosynthesis occurs mainly in the leaves
cross section of leaf. Chloroplasts are found mainly in the palisade layer (palisade mesophyll)
While leaves on different plants are slighlty different , in shape and size. All leaves are specially adapted for photosynthese in a number of ways:
- A broad shape is used to help photosynthesis as it provides a large surface area in order to absorb light and CO2
- A Flat shape is used to help photosynthese as it means the gasers dont have too far to diffuse.
- By containing a network of veings it helps supply water from the roots as well as takiny away the products
- The chloroplasts are…
