What is the process by which plants make their own food?​

Sagot :

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.
