Detailed explanation-1: -In most plants, the leaves are the main food factories. They capture the sun’s energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis.
Detailed explanation-2: -Light is absorbed through the top layers of the leaf, known as the cuticle and upper epidermis .
Detailed explanation-3: -The surface of the leaf absorbs the blue and red wavelengths while the green light is absorbed deeper within the plant. This light is what’s absorbed by the chloroplasts and is most effective in photosynthesis and the conversion of energy.
Detailed explanation-4: -The blade of the leaf is the relatively wide, flat part of the leaf that gathers sunlight and undergoes photosynthesis. Thepetiole is the part that attaches the leaf to a stem of the plant. This occurs at a node.
