Study Notes
Photosynthesis
-
Photosynthesis is the process by which plants make carbohydrates (sugars) from raw materials using light energy
-
Raw materials are carbon dioxide and water
-
Oxygen is released as a waste product
-
The reaction needs chlorophyll (a green pigment) to trap light energy from the sun
-
The overall process can be summarised as:
Carbon dioxide + Water + Light Energy → Glucose + Oxygen
-
The balanced chemical equation for photosynthesis is:
6CO₂ + 6H₂O + Light Energy → C₆H₁₂O₆ + 6O₂
-
Light energy is converted into chemical energy in the bonds of the glucose molecules
-
Glucose is usually converted to sucrose for transport throughout the plant or to starch for storage
Leaf Structure
- The leaf is made up of a broad, flat lamina
- The lamina is attached to the rest of the plant by a petiole (leaf stalk).
- Vascular bundles run through the petiole and form the veins in the leaf.
