How does humidity affect the rate of transpiration
Think of a puddle of water evaporating on the ground. Will that puddle evaporate more quickly with wind or without wind? The water molecules will only evaporate when they gain enough kinetic energy to break free and become vapor. Wind facilitates this by giving the molecules that extra push of energy.
The same applies to plants and transpiration. Wind will increase the rate of transpiration and water-loss through the leaves of a plant. However, initial water-loss triggers the closing action of the stomata (openings by which water evaporates) and transpiration rate will slow.
Low humidity makes the transpiration very active because the water molecules move from the region of higher concentration (plant) towards the region of lower concentration (dry or less humid atmosphere).
Mist or high humidity outside the leaves slows the rate of transpiration, as transpiration relies on the evaporation of water vapour through the stoma (stomata).
The drier the air the higher the transpiration rate
*stomata -open-increased transpiration -closed-decreased transpiration *consequence of gas exchange -tradeoff of more gas exchange resulting in more transpiration *environmental factors -humidity -air movement -evaporative cooling -wind stress -intense light/heat
Stomata open in the presence of bases and close in the presence of acids. Therefore, the rate of transpiration is higher in bases due to that they are losing more water through their open stomata.
They increase surface area . They create a covering with air. It reduces transpiration rate
i dont no. thats what i need to no.
The stomata on the underside of the leaf regulate transpiration. The leaf surface area helps to estimate the number of stomata, which could speed up or slow the rate of transpiration.
High humidity reduces the rate of transpiration.
Bigger the SA:V ratio , transpiration sucks.

What is "it"? Please be specific with your question if you wish an answer.

By transpiration. Water molecules pass out of the leaf by diffusion following the concentration gradient from higher concentration to lower concentration. The rate of transpiration varies. Factors that affect the rate of transpiration includes wind speed, light intensity, temperature and humidity
Water supply: If water is in short supply, then the plant will close its stomata. This will cut down the rate of transpiration. Transpiration decreases when the water supply decreases below a certain level.
Stomata open in the presence of bases and close in the presence of acids. Therefore, the rate of transpiration is higher in bases due to that they are losing more water through their open stomata.
The rate of transpiration is the position of air bubble
the answer is when you evaporate it poops out all over you and suck through the nostrils

Under the humid condition the rate of transpiration decreased, this is due to the fact that the water potential of the air surrounding the leaf was increased by the mist, this in turn minimized the gradient of water potential between the leaf and its surrounding environment, thus the process of transpiration lessened to some extent. This occurred because the rate of transpiration decreases proportionally to the amount of humidity in the air. Under windy conditions the rate of transpiration showed an increase, this is due to the fact that wind removes water vapor from the leaf's surrounding, resulting in a broader concentration difference between the leaf and its outer environment, therefore the leaf possessed a higher water potential as compared to its outside environment, and a more rapid loss of water occurred through the stomata.
