Multiple choice

Water is the ideal material for the disposal of solar energy absorbed in excess by plants because

  1. the solubility materials in water is high and enables free movement of water

  2. water is easily available to plants and its specific heat is high

  3. the upward movement of water creates a difference in water potential

  4. evaporation of water from the leaf surface creates absorption of mineral salts

B Correct answer
Explanation

Water's high specific heat means it can absorb large amounts of heat energy with minimal temperature change, making it ideal for thermal regulation in plants. Combined with its ready availability, this makes it perfect for dissipating excess solar energy.
