Question

Topography of leaf in transpiration define?​

Answer 1

Answer:

Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. It is the "engine" that pulls water up from the roots to: 1. supply photosynthesis (1%-2% of the total); 2. bring minerals from the roots for biosynthesis within the leaf; 3, cool the leaf. Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.

Answer 2

• Transpiration is the loss of water from a plant in the form of water vapor.
• Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem.
• In the leaves, small pores allow water to escape as a vapor.
• Of all the water absorbed by plants, less than 5% remains in the plant for growth.
