Revision notes on photosynthesis, chlorophyll, stomata, and modes of nutrition in plants.
mediumRevision notes
Key points
- Green plants make food by photosynthesis.
- Chlorophyll helps leaves capture sunlight.
- Stomata allow exchange of gases in leaves.
Photosynthesis
Plants use carbon dioxide, water, and sunlight to make food. Oxygen is released during this process.
Leaves are called food factories of plants because most photosynthesis happens there.
Other modes of nutrition
Some plants depend partly or fully on other organisms for nutrition.
Examples include parasitic plants and insectivorous plants.
Quick practice
- Write the raw materials needed for photosynthesis.
- What is the role of chlorophyll?
- Why are leaves important for plants?
