What to Focus On
- Plants need sunlight and water for growth.
- A plant in sunlight with water grows better than a plant in the dark with water.
- A plant with sunlight but no water may die.
- Leaves are broad and flat to capture sunlight efficiently.
- Chlorophyll gives leaves their green colour and helps in photosynthesis.
- Starch is a storage form of carbohydrate.
- Photosynthesis needs sunlight, water, carbon dioxide, and chlorophyll.
- Destarching means keeping a plant in the dark for two to three days.
- Caustic soda absorbs carbon dioxide from air.
Common Mistakes to Avoid
Plants make food only when they are in sunlight, so light alone is enough for growth.
Photosynthesis makes starch directly.
Any green-looking part of a leaf must make starch equally well.
Memory Tips
Photosynthesis needs sunlight, water, carbon dioxide, and chlorophyll
Leaves as food factories
