Final answer:
Plants convert radiant energy from the Sun into chemical energy through photosynthesis. Solar energy is absorbed by plants and used to convert carbon dioxide and water into glucose and oxygen. The energy captured from sunlight is stored in the chemical bonds of glucose.
Step-by-step explanation:
Plants convert radiant energy from the Sun into chemical energy by a process called photosynthesis. Through photosynthesis, plants absorb solar energy from the sun and use this energy to convert carbon dioxide and water into glucose and oxygen. The energy captured from sunlight is stored in the chemical bonds of glucose, which can later be used to fuel the organism's life functions.
