How do you think windy conditions will affect the flow of the transpiration stream?
Windy conditions can increase the rate of transpiration by promoting more evaporation from the leaf surface. This can create a steeper concentration gradient, leading to faster movement of water through the plant. However, excessive wind can also cause plants to close their stomata to prevent water loss, potentially reducing the transpiration rate.
Did any of the environmental factors heat light or wind increase the transpiration rate more than the others Why?
Wind generally increases transpiration rate more than heat or light because it creates a lower humidity and a higher concentration gradient between the leaf stomata and the surrounding air. This leads to faster water evaporation from the leaf surface. Heat and light can also increase transpiration by accelerating the rate of water evaporation, but wind has a more direct and significant impact.
How does the transpiration affects the distribution of stomata in a leaf?
Transpiration in a leaf causes water to be lost through the stomata, leading to a decrease in internal water pressure. To compensate for this loss, stomata are typically distributed more on the lower surface of a leaf where there is less direct sunlight and wind exposure, helping to reduce excessive water loss and maintain the plant's hydration levels.

What environmental factors increased the rate of transpiration?
Heat and wind.
How does wind affect the rate of transpiration in plants?
Wind can increase the rate of transpiration in plants by causing water to evaporate more quickly from the leaves. This is because wind removes the layer of humid air surrounding the leaf, allowing for more efficient water loss through the stomata.
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 mist affect the rate of transpiration?
How does humidity affect the rate of transpiration
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
How wind affects 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.
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.

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 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.
