Transpiration rates decrease proportionally to the amount of humidity in the air. This is because water diffuses from areas of higher concentration to areas of lower concentration. Thus, when the air spaces between the mesophyll cells in a leaf are saturated with water vapor, and the air outside the leaf is likewise saturated, there is a shallow gradient. A shallow gradient results in a slower transpiration rate. Conversely, if the air outside the leaf is relatively dry, the gradient becomes steep and the rate of transpiration increases.

Which factor affects most in transpiration-humidity or light intensity?
Light intensity
What is the rate of transpiration effected by?
The rate of traspiration is effected by light intensity, humidity and wind velocity etc.
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.
When transpiration would be minimum?
Transpiration would be minimum when the environmental conditions are cool, humid, and still. This is because high humidity reduces the rate of water loss from the plant leaves, while cool temperatures slow down the metabolic processes that drive transpiration. Calm conditions also prevent the movement of air that can increase evaporation from the leaves.
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...
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.
How does high humidity affect transpiration?
High humidity reduces the rate of transpiration.

Light intensity

Name a factor that affects transpiration rate
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.
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
When transpiration is minimum?
humidity
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 atmospheric conditions contribute to the highest rate of transpiration?
High temperatures, low humidity, and good air circulation all contribute to the highest rate of transpiration in plants. These conditions increase the rate of evaporation from the stomata on the plant's leaves, leading to more water loss through transpiration.
What atmospheric contribute to the highest rate of transpiration?
Factors such as low humidity, high temperature, and windy conditions contribute to the highest rate of transpiration in plants. Low humidity creates a larger gradient for water to move from the plant to the atmosphere, high temperatures increase the kinetic energy of water molecules, and windy conditions help remove water vapor from around the plant, promoting transpiration.
What factors effect the rate of transpiration?
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.
