  • Different environmental conditions have an effect on transpiration rate in plants. Warm conditions, wind and bright sunlight speed up transpiration rate. Cool conditions, no wind and humidity slow down transpiration rate. Do not take measurements directly after changing the conditions.

The rate of transpiration is always affected by a group of environmental factors like light, temperature, wind, atmospheric humidity, atmospheric pressure, availability of soil water, anti-transpirants. Light: The presence of light favours the opening of stomata and transpiration takes place through them.

Environmental factors that affect the rate of transpiration 1. Light Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (). Light also speeds up transpiration by

During transpiration plants move water from the roots to their leaves for photosynthesis in xylem vessels. Glucose made in photosynthesis is then moved to all cells in phloem vessels for respiration.

The velocity of wind greatly affects the rate of transpiration. Fast moving air currents continually bring fresh, dry masses of air in contact with leaf surfaces and thus maintain a high rate of transpiration. 5.

There are, however, a number of external factors that affect the rate of transpiration, namely: temperature, light intensity, humidity, and wind. The opening and closing of stomata. Different environmental conditions trigger both the opening and closing of stomata.

Factor Change in factor that increases transpiration rate Explanation Temperature Increase Increases molecular movement so that more water molecules evaporate from cell surfaces. The rate of ...

Atmospheric Pressure: Atmospheric pressure affects transpiration, because it has influence on the rate of vaporization. When atmospheric pressure is high, the rate of transpiration is low. However, in any given locality variations in the atmospheric pres­sure are too slight to have any considerable effect upon transpira­tion rates.

The experiment can then be repeated but this time changing the following environmental conditions. Wind To measure how wind affects transpiration a hairdryer or fan that blows cold air can be used to blow the leaves.

The larger the boundary layer, the slower the rates of transpiration. Plants can alter the size of their boundary layers around leaves through a variety of structural features. Leaves that possess many hairs or pubescence will have ...
