* Radiant Energy (Sunlight): The sun emits light and heat, which are forms of radiant energy.
* Photosynthesis: Plants use a process called photosynthesis to capture this radiant energy. In photosynthesis, they use sunlight, water, and carbon dioxide to create sugars (glucose).
* Chemical Energy: Glucose is a type of sugar that stores chemical energy. This energy is what fuels the plant's growth and development.
Mechanical energy is the energy of motion. While plants do move (like opening and closing their flowers or growing towards light), this movement is a result of the chemical energy they've produced through photosynthesis, not the direct conversion of radiant energy into mechanical energy.
