Photosynthesis not only helps plants grow but also plays a major role in the Earth’s ecosystem. Without it, there would be no oxygen for humans and animals to breathe, and no food at the base of the food chain. This process also helps reduce carbon dioxide in the atmosphere, which is important for controlling the Earth's climate. Plants store the glucose they make for energy or use it to build strong stems, roots, and leaves. In this way, photosynthesis supports all life on Earth, directly or indirectly, by providing food and clean air.Photosynthesis is the process by which green plants, algae, and some bacteria make their own food using sunlight, water, and carbon dioxide. This process mainly takes place in the leaves, where a green pigment called chlorophyll captures sunlight. The plant uses this energy to change carbon dioxide from the air and water from the soil into glucose (a kind of sugar) for energy.

MY NOTES: Photosynthesis is the way plants make food and oxygen using sunlight, water, and carbon dioxide.
