Photosynthesis Concepts and Misconceptions

The video clarifies that plants do not breathe like animals but use photosynthesis to produce energy. It explains how roots absorb water and nutrients, which are transported to leaves. Leaves use sunlight, carbon dioxide, and water to create glucose, the plant's energy source. Oxygen, a byproduct, is released into the air.
