Advantages and Disadvantages of Transpiration

Let us conduct an in-depth investigation into the significant advantages and disadvantages of transpiration.

Advantages and Disadvantages of Transpiration

Advantages and Disadvantages of Transpiration

Advantages of Transpiration

  1. It makes a suction force, which helps the sap rise.
  2. It influences the diffusion pressure deficit, indirectly facilitating diffusion through the cells.
  3. It affects the roots’ ability to absorb water and minerals.
  4. It aids in the evaporation of excess water.
  5. It plays a crucial role in the transport of nutrients from one portion of the plant to another.
  6. It maintains a suitable temperature for the plant’s leaves and cools the plant’s body.
  7. It causes the opening and closing of stomata, which influences photosynthesis and respiration indirectly.

Disadvantages of Transpiration

  1. Desiccation often results from a water deficit (capillary water) brought about by transpiration.
  2. Rapid transpiration causes a midday water deficit in the leaf (temporary wilting). If this condition persists for an extended period of time, permanent water deficit (permanent wilting) may develop, which could prove fatal to the plants.
  3. Numerous xerophytes must modify their morphology to reduce transpiration. These modifications add additional stress to the plants.
  4. The excessive rate of transpiration stunts plant development.
  5. Since approximately 90 percent of the water absorbed is lost through transpiration, the energy used for water absorption and conduction is wasted.
