Correct option is B
Correct answer : (b) Can cause wilting of plants
- The transpiration offers several advantages like cooling, facilitating nutrient transport, and providing water for photosynthesis, one significant disadvantage is that excessive transpiration can lead to water loss.
- If the rate of water loss through transpiration exceeds the plant's ability to absorb water from the soil, it can cause wilting.
- Wilting occurs when the plant loses more water than it can replace, causing a drop in turgor pressure and making the plant droop.
Information Booster:
· Cooling: Transpiration cools plants by releasing water vapor, which helps to regulate their temperature, preventing overheating.
· Photosynthesis: Transpiration helps in providing water to the leaves, which is essential for photosynthesis.
· Transporting minerals: Transpiration also aids in the upward movement of water and minerals from the roots to the leaves, playing a crucial role in nutrient transport.
· Wilting: Wilting is a common result of water stress, which can occur due to insufficient water uptake or excessive transpiration, especially during hot and dry conditions.
Plants can adapt to reduce excessive transpiration through mechanisms like closing stomata or leaf adaptations such as waxy coatings to minimize water loss.
