Answer:
This is the diffusion (loss of water vapor) from the stomata (most cases) of a plant to its external environment.
It involves movement of water vapor down the water potential gradients; that is ; from higher water potential inside the leaf to lower water potential in the surrounding environments.
its cools the plant’s internal temperature as water vapour conveys heat out of plants' cells.
Answer:
upper one is translocation and lower one is deletion
Explanation:
Any form of precipitation, including rain, snow, hail, fog, or dew, that is high in acid pollutants, especially sulfuric and nitric acid. Acid precipitation has a pH of less than 5.6 (the normal acidity of unpolluted atmospheric water) and is often less than pH 5.0.
Air pollution can kill trees and can cause chronic disease
Smaller molecules diffuse easily as compared to the larger molecules. In other words, smaller is the size of molecule, easier and faster is its diffusion across a semipermeable membrane.
