Humidity - increased humidity decreases transpiration, as the air is already saturated with water, and so the water potential gradient is smaller, and so less water is lost by transpiration.

Temperature - increased temperature increases transpiration as the water has a greater kinetic energy and so there is more evaporation of water.

Wind/air movement - in still air, a shell of highly saturated air surrounds the air, decreasing the water potential gradient and decreasing transpiration rate, but wind destroys this shell of saturated air so there is a bigger water potential gradient, amd more transpiration.

Light intensity - light is needed for the stomata to open - they do not open at night time (unless the plants are xeromorphically adapted desert plants or plants living in other harsh environments such as salt marshes).

Internal factors that affect transpiration are the number of stomata, leaf area, the cuticle (thick waxy cuticles prevent water loss, whilst thinner and less waxy cuticles allow more water to be lost. Distribution of stomata also affects transpiration - most plants have most of the stomata on the lower surface of the leaf where the stomata are less exposed to environmental conditions.

What factors influence the rate of transpiration in plants and what affects transpiration?

The rate of transpiration in plants is influenced by factors such as temperature, humidity, wind speed, and light intensity. These factors affect transpiration by impacting the rate at which water evaporates from the plant's leaves.


What factors can cause an increase in the rate of transpiration?

Factors that can cause an increase in the rate of transpiration include high temperatures, low humidity, increased air movement, and intense sunlight. These conditions can lead to faster evaporation of water from plant leaves, resulting in higher transpiration rates.


What factors influence the plant transpiration rate?

Factors that influence the plant transpiration rate include environmental conditions such as temperature, humidity, wind speed, and light intensity, as well as plant-specific factors like leaf surface area, stomatal density, and plant species.


How does a type of plant affect transpiration?

*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


What increase the rate of transpiration in a plant?

The rate of transpiration depends on some environmental factors such asTemperature and windWhen the temperature is high rate of evaporation increases as warm air can hold more water vapours than the cold air. Windy condition also increase the rate of transpiration as wind remove water vapours from around the leaf. HumidityWhen there is more humidity in air, transpiration would be considerably low as the air is already saturated with water vapours and it will be unable to absorb more water so little water will diffuse out of the leaves. LightLight greatly influences the opening and closing of stomata. During day light the stomata remain open and allow water vapours from the leaves to diffuse into the atmosphere. Atmospheric pressureReduction in the atmospheric pressure enhances the rate of transpiration.

How do you think temperature will effect transpiration in a plant?

Increase in temperature also increases the rate of evaporation of water, hence temperature will effect transpiration

Does a leaf sweat?

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


What is the operational definition of the rate of transpiration?

The rate of transpiration is the position of air bubble

Why water lost in transpiration is not constant?

Because there is no consistancy in the rate of transpiration


What environmental factor has the greatest effect on transpiration?

The environmental factor that has the greatest effect on transpiration is humidity. High humidity levels reduce the rate of transpiration because there is already a lot of moisture in the air, making it harder for water to evaporate from the plant's leaves. Conversely, low humidity levels increase transpiration as the drier air creates a larger gradient for water to move out of the plant.


List environmental factors that effect the rate at which plants transpire?

amount and duration of sunlight (winter/ summer) wind exposure temperature relative humidity of the surrounding air amount of soil water available to the plant amongst others...


How does high humidity affect transpiration?

High humidity reduces the rate of transpiration.
