Asked in Premeth past paper pool — Biology

The biological process which uses the property of latent heat of vapourisation of water is

Correct answer: A. Transpiration

  • A. Transpiration
  • B. Translocation
  • C. Excretion
  • D. Egestion

Explanation

The correct answer is transpiration. Transpiration is the process by which water is absorbed by plant roots and then evaporated from the leaves into the atmosphere. This process utilizes the latent heat of vaporization, as water changes from liquid to vapor, helping in cooling the plant and also in nutrient uptake. In contrast, translocation involves the movement of nutrients and food within the plant and does not require the latent heat of vaporization. Excretion and egestion involve the removal of waste substances from the body, which do not directly involve the vaporization of water.

About Plant Nutrition and Transport

Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
