Detailed explanation-1: -Transpiration is affected by air movement. As the movement of air increases, the concentration gradient is increased, so the rate of transpiration increases. Transpiration is affected by light intensity. As the light intensity decreases, the stomata close up and there is a reduction in photosynthesis.

Detailed explanation-2: -Uptake of Nutrients, is one of the main benefits of the Cohesion-Tension mechanism, triggered by transpiration, which pulls water out of the soil into the roots. This moves water and other nutrients absorbed by roots to the shoots and other parts of the plant.

Detailed explanation-3: -The continuous evaporation of water (or transpiration) from the cells of a leaf crates a kind of suction which pulls up water through the xylem vessles. Thus, transpiration helps in the upward movement of water and dissolved minerals from the roots to the leaves through the stem.

Detailed explanation-4: -Instead, it is transported through a process called osmosis, which is similar to diffusion. In osmosis, water molecules move from areas of lower solute concentration and higher water concentration to areas with higher solute concentration and lower water concentration.
