Explanation:
Detailed explanation-1: -When plants lack light, they don’t produce chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy, ‘’ meaning stems become long and thin and appear to be reaching toward the source of light.
Detailed explanation-2: -The light energy (from the sun) then triggers a chemical reaction that breaks down the carbon dioxide and water molecules. This process creates a sugar called glucose and also produces oxygen. The glucose is then broken down by organelles called chloroplast and provide the energy needed to grow and repair plants.
