expert please answer me forth the questions are on upside

Dear Student,

Ans a)
Loss of water through the pores present in leaves called stomata in the form of vapours is called transpiration. The stomata are the small pores present in the leaves. 

Ans b) Transpiration helps the plants to take nutrients from soil. It also keeps the plant cool in hot weather conditions.

Role of transpiration in plants is as follows:

  • Creates transportational pull for transport of water in plants.
  • Provides water for photosynthesis.
  • ​Helps in the uptake of  minerals from soil to upper parts of plant.
  • Cools the surface of the leaves (due to the evaporation of water).
  • Keeps the cells turgid; hence, maintains their shape.

Ans c) Arrows B and C indicate the process of transportation of water and minerals from the roots to the leaves of the plant. The arrows point upwards since the movement of water is upwards.

P.S. Kindly post separate questions in separate threads.

Regards
