What is transpiration why is it necessary

Answer 1

Hey mate!

This is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Plants need to cool themselves for several reasons. ... The stomata (pores) must open to take in carbon dioxide for photosynthesis (especially important on mornings of sunny days).

Transpiration serves three essential roles: Movement of water and nutrients – Moves minerals up from the root (in the xylem) and sugars (products of photosynthesis) throughout the plant (in the phloem). Cooling – 80% of the cooling effect of a shade tree is from the evaporative cooling effects of transpiration.
