Harnessing the Sun: How Plants Turn Light into Life

The video explains how organisms, particularly plants, obtain energy to survive. It focuses on photosynthesis, a process where plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Chlorophyll in plant cells aids this process, making plants green. The energy from sunlight is transformed into chemical energy stored in glucose, which plants can use or store. Photosynthesis also releases oxygen, essential for human respiration. Plants and algae are producers, creating energy that supports life on Earth. The video concludes by introducing consumers, organisms that rely on plants for energy.
