Factors That Affect the Rate of Transpiration
There are Five Factors that Affect the Rate of Transpiration. The rate of transpiration is affected by several factors.

Is affected by several factors.
. Factors affecting the transpiration rate are the same as the factors affecting the evaporation rate. The maximum opening of stomata is done by blue light. IFactors Localized Within the Plant.
Light intensity air movement temperature and humidity. Effect on the rate of transpiration. When it is absent the stomata remain closed.
In short higher temperature increases the. Stomata Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. The table below explains how factors increase the rate of.
The rate of transpiration increases with the increase in the availability of water in the soil. Water is evaporated through the stomata. How do environmental factors affect the rate of transpiration.
The rate of transpiration depends upon the rate of absorption of soil water by roots. The rate of transpiration. Ibis diffusion can take place only if the water vapor content of the outer atmosphere is less than that of the inter-cellular spaces of the leaf.
What increases the rate of transpiration. Blue and red light are the most effective in the. This is further influenced by a number of soil factors like soil water soil particles soil temperature soil air etc.
The evaporation of water from plants. How does light increase transpiration. Light affects transpiration because it is directly involve in.
It occurs mainly at the leaves while their stomata are open for the passage of CO2 and O2 during has exchange for photosynthesis. The rate of transpiration is inversely proportional to the relative humidity ie the rate of transpiration is. If the surrounding temperature of a plant increases water will evaporate from the cell surface this will cause the rate of diffusion increases of water from the leaf.
When stomata are open transpiration rates increase. The following points highlight the ten important factors that affecting transpiration. Light also increases the temperature thus affecting the rate of transpiration.
Special cells called guard cells control each pores opening or closing. Factors that affect the rate of transpiration also affect water uptake by the plant. Many environmental factors such as intensity of light temperature atmospheric humidity wind availability of soil water etc greatly affect the rate of transpiration.
Light Humidity Temperature Atmospheric pressure Wind speed or velocity. This follows the simple law of diffusion. The external and internal factors affecting the rate of transpiration are as follows.
Availability of Water 7. There are various factors affecting the rate of transpiration in plants. If water is scarce or the roots are damaged a plant may wilt.
Factors affecting rate of Transpiration. It is the most essential factor since it plays. Transpiration is affected greatly by the environment factors such as temperature light relative humidity wind and so on.
In a dry soil the soil solution becomes. What 5 factors affect the rate of transpiration for a plant. The rate of transpiration can be affected by.
If all other conditions are favorable for transpiration the water absorbing capacity of the root surface and the transpiring capacity of the leaf surface regulate the rate of transpirationIf transpiration is greater than absorption a water deficit results which causes a reduction in the transpiration rateii. It also enhances the capacity of the air to absorb more water. The environmental factors affecting the rate of transpiration are.
The rise in the temperature of the air heats the water insider the leaves more quickly causing it to evaporate faster. Increased light intensity will increase the rate of photosynthesis so more water is drawn into the leaves where photosynthesis primarily takes place and therefore the rate of transpiration is greater. Factors that affect transpiration in plants The light intensity temperature humidity wind and water supply will all affect the transpiration rate.
Temperature humidity air movement and light can affect the rate of transpirationIf the air is still water vapour diffusing out of the leaf will tend to accumulate around the stomata pores. Factors affecting transpiration rate. The rate of transpiration can be affected by certain environmental changes.
Following factors affect the rate of transpiration. When they are closed transpiration rates decrease.
