Question
Transpiration is a necessary evil in plants. Explain.
Solution
Transpiration is a necessary evil in plants because it is inevitable but potentially harmful. Loss of water from the plant results in wilting and causes the death of a plant if a condition of drought is experienced. But transpiration is of great significance for the plant.
- Water is conducted, in most tall plants due to transpiration pull.
- Minerals dissolved in water are distributed throughout the plant body by Transpiration Stream.
- Evaporation of water from the cells of leaves has a cooling effect on plants.
- The wet surface of leaf cells allows gaseous exchange.
