Factors that affects the rate of transpiration of plants:
The process whereby water vapour evaporates from the underside of the leaves is called transpiration.
Here are the factors affecting it:
1) Light - The brighter it is, the bigger the stoma will it become, hence, when light intensity increases, the rate of transpiration increases too.
2) Humidity - The lower the humidity, the faster the rate of transpiration.
3) Wind speed - The faster the wind speed, the higher the rate of transpiration.
4) Heat - The hotter the weather, the higher the rate of transpiration.
