Answer:
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. Light, carbon dioxide, and water play important roles in this process:
1. Light: Light energy is absorbed by pigments in the chloroplasts of plant cells, such as chlorophyll, which allows the plants to capture the energy from the sun. This energy is then used to power the chemical reactions that convert carbon dioxide and water into glucose.
2. Carbon dioxide: Carbon dioxide is a gas that is taken in by plants through tiny pores on their leaves called stomata. This gas is then used as a building block to create glucose during photosynthesis.
3. Water: Water is absorbed by the roots of the plant and transported to the leaves through specialized tubes called xylem. During photosynthesis, water is split into oxygen and hydrogen ions in a process called photolysis. The hydrogen ions are used to build glucose, while the oxygen is released back into the atmosphere.
In summary, light provides the energy needed for photosynthesis, carbon dioxide provides the carbon atoms needed to build glucose, and water provides the hydrogen atoms needed to build glucose and also releases oxygen into the atmosphere.
