Plants make their own food through a process called photosynthésis.
Process of Photosynthésis:
- Light Absorption - Plants absorb sunlight using a pigment called chlorophyll, which is primarily found in the leaves.
- Water Uptake - Water is absorbed by the roots from the soil and transported to the leaves through the plant’s vascular system.
- Carbon Dioxide Intake - Carbon dioxide is taken in from the air through small openings in the leaves called stomata.
Importance of Photosynthésis:
- Food Source - Photosynthésis is the primary way that plants produce food, which is essential for their growth and development. The glucose produced provides energy for the plant’s cellular activities.
- Oxygen Production - Photosynthésis produces oxygen as a byproduct, which is crucial for the survival of most living organisms, including humans. It helps maintain atmospheric oxygen levels.
- Carbon Dioxide Regulation - By taking in carbon dioxide, plants help regulate atmospheric CO2 levels, which is important for controlling the greenhouse effect and combating climate change.
