Photosynthesis |
Photosynthesis is the chemical process where plants use sunlight energy to produce their own food. |
|
|
How food is made in green plants |
Plants use light to combine carbon dioxide with water ( raw materials) to make glucose a simple carbohydrate. Chlorophyll in the leaf is uses to effect the reaction and oxygen gas is given off as by product. Plants convert light energy into chemical energy which is stored in the food |

Conditions for photosynthesis |
Chlorophyll Light energy Carbon dioxide Water |
|
|
Role of chlorophyll |
To absorb light energy and convert it to chemical energy causing carbon dioxide to combine with hydrogen |
|
|
Role of light |
To split water into its components hydrogen and oxygen. |
|
|
Storage of the products of photosynthesis |
It is used in the cell during respiration Taken to different parts of the plant to be stored for further use (translocation) |
|
|
Epidermis |
Two layers of cells closely fitted at the top and bottom of the leaves The upper epidermis has a waxy layer (cuticle) on its outside Lower epidermis has more stomata than the upper |
|
|
Guard cells |
Are crecent shaped, surround each stoma and controls the opening and closing of the stomata |
