Heat increased the rate of transpiration more than light.This is because the temperature of the surrounding increased resulting in the rate of evaporation to increase so water vapour from the plant escaped through the stomata

Once water enters the root from the soil it travels to the xylem vessels in the middle of the root. The xylem vessels transport the water up through the stem and into the leaves of the plant. The leaves have a high concentration of dissolved minerals produced from photosynthesis and an overall low water concentration. Water is thus transferred from the xylem vessels to the cells in the leaves via osmosis.The cells which water are transported to are also known as stomata .

as wind speed increases, rate of transpiration increases. Wind blows away the water vapour in the air, leaving more space for water vapour given out by the stomata of the leaves during transpiration.

2. temperature
higher temperature increases rate of transpiration. more water evaporates and leaves the leaf. As water evaporates faster to form water vapour, transpiration rate is higher.

3. humidity
when air is damp and moist, less water evaporates out of leaf, transpiration slows down as water vapour in the air is saturated in the surrounding air.

The force behind this upward movement is called capillary action, a force of attraction between molecules that causes liquids to move up narrow tubes, such as those inside a plant's stem,xylem tube. Some of the water absorbed by a plant's roots is used for photosynthesis, but much is lost to the environment . During photosynthesis, tiny pores on the surface of the leaves, called stomata, open to permit the intake of carbon dioxide and the release of oxygen. Because the stomata must remain open for the exchange of gases, large amounts of water are lost to the environment through evaporation. Water that evaporates from the leaves is continually replaced with water that is absorbed through the roots.

In fact, for 4/9 of the plants tested, their transpiration rate was lower with the light than without. Wind most likely increased the rate of transpiration the most because the wind was able to most effectively cause molecules of water to evaporate or blow off of the plant causing transpiration.

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves (stomata) where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.
