Question

What is Wilting of plants?

• A. Removal of leaves by the plants
• B. Loss of rigidity of non-woody parts of plants
• C. Respiration process in night by the plants
• D. Guttation

Answer 1

Answer: (B)

Loss of rigidity of non-woody parts of plants

• Wilting is the loss of rigidity of the nonwoody parts of plants.
• This occurs when the cells of the plant tissue especially leave have very low water content or no water content at all.
• Wilting is the defense of the plant against the absence of the water. When there is less amount of water present the leaves of the plant will wilt or roll themselves so that its surface area decreases and therefore the rate of transpiration which takes place through stomata will also decrease which in turn will also decrease the loss of water that is present in the plant.
  
• Therefore wilting is the process where the nonwoody part of the plants will lose their rigidity and curl or roll to decrease their surface area so that less of the water is the loss in the process of transpiration through stomata
• So, the correct option is B ' loss of rigidity of nonwoody parts of plants'.
