The correct answer is option (A) trichomes.
Trichomes are the fine extensions from the epidermal surfaces covering the plant body. They are the result of epidermal cell division. They can be unicellular, multicellular and even glandular. They are characteristically present on the epidermal surfaces of leaves and roots. They reflect the solar radiation and help in mainitaining the internal temperature and reducing water loss. In roots, they absorb water and minerals and in leaves, they reduce water loss, lower the plant temperature. Plants may use trichomes to detect herbivore attacks as a defense mechanism.
Starting with the retention of light by chlorophyll, the light responses change over light vitality into concoction vitality as ATP and NADPH. The ATP gives the vitality, and the NADPH supplies the electrons for the Calvin cycle, which changes over carbon dioxide to sugar.
