1. Sunlight: Plants capture light energy from the sun using a green pigment called chlorophyll.
2. Water: Plants absorb water from the soil through their roots.
3. Carbon dioxide: Plants take in carbon dioxide from the air through tiny openings on their leaves called stomata.
4. Photosynthesis: Inside the chloroplasts of plant cells, sunlight energy is used to convert water and carbon dioxide into glucose (a type of sugar) and oxygen. This process releases oxygen as a byproduct.
The glucose produced in photosynthesis is a simple sugar that serves as the building block for more complex organic molecules, such as carbohydrates, proteins, and fats. These molecules provide the plant with energy for growth, repair, and other essential functions.
So, in essence, plants use sunlight to power the chemical reactions that allow them to create their own food, making them the foundation of most ecosystems.
