Study Notes
Requirements for Photosynthesis
- Essential components include chlorophyll, sunlight, water, and carbon dioxide.
Raw Materials
- The primary raw materials for photosynthesis are carbon dioxide and water.
De-starching Process
- De-starching involves leaving a plant in darkness for a minimum of 48 hours to eliminate starch reserves.
Importance of De-starching
- De-starching is crucial to demonstrate that light is necessary for photosynthesis, as it ensures that any produced starch during the experiment is a result of the photosynthetic process in the presence of light.
Variegated Leaves
- 'Variegated' refers to leaves having some areas without chlorophyll, resulting in white patches, indicating those areas cannot perform photosynthesis.
