Materials and Methods The following are the materials that were used for our project: 1.Gas pressure sensor 2..Dogwood leaf with stem included 3. Glucose made in photosynthesis is then moved to all cells in phloem vessels for respiration. 4. The rate of photosynthesis can be limited by the factors: temperature, carbon dioxide concentration and light intensity (draw graphs of each factor vs rate of photosynthesis). Due to high winds, the water molecules from the surface of the leaves is removed faster leading to vapor pressure gradient inside and outside the leaves. Wind When there is no breeze, the air surrounding a leaf becomes increasingly humid thus reducing the rate of transpiration. Transpiration is the process in which plant roots absorb water and then release the water in the form of vapour through the leaves. The difference between the control and the heat (p < .005) and the wind (p = .05) were both significant. Factors Affecting the Rate of Transpiration. Transpiration is the evaporation of water from plants. In a nut shell, the combined affect of light causes opening of stomata and incerases the rate of vaperisation of water. The remaining 97–99.5% is lost by transpiration and guttation. The tiny holes on the leaves are known as stomata. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today?

Open stomata allow water vapor to leave the leaf but also allow carbon dioxide (CO 2) to enter. ... a greater number of distances of the fan as this would provide me with more security that there is a linear trend in wind speed and transpiration. Wind velocity: The higher the wind, the greater the transpiration. 5. Factors Affecting the Rate of Transpiration. Transpiration is affected greatly by the environment factors such as temperature, light relative humidity, wind, and so on. The results show that the plants placed in wind have a higher rate of transpiration than those in direct light only. out of the leaf. Transpiration is an important factor in the water cycle as it is one of the major sources of water into the atmosphere.Providing 10% of the total water in the atmosphere, this process is nearly identical to perspiration or sweating in animals. But even internal factors affect the rate of transpiration. Transpiration: Transpiration is defined as the process where the plant loses its water from the openings in the leaves called stomata. Carbon dioxide entry: When a plant is transpiring, its stomata are open, allowing gas exchange between the atmosphere and the leaf. The wind will also clear the air of any humidity produced by the plant’s transpiration, so the plant will increase its rate of transpiration. The stomata also enable the release of carbon dioxide, which along with water, is a byproduct of photosynthesis. More Direct Heat Will Increase Transpiration B. Driving force: The driving force for transpiration is the difference in water potential between the soil and the atmosphere surrounding the plant. The rate of photosynthesis can be limited by the factors: temperature, carbon dioxide concentration and light intensity (draw graphs of each factor vs rate of photosynthesis). When a breeze is present, the humid air is carried away and replaced by drier air. The movement of the air increases the rate of transpiration by removing the saturated air around the leaves. The rate at which transpiration occurs refers to the amount of water lost by plants over a given time period.

This movement of air from cooler to warmer areas is wind. This is because wind moves water-saturated air away from stomata, which reduces external water vapor concentration, increasing the gradient, so water moves out of the leaf. A strong … When there is a high rate of wind activity, transpiration is relatively higher since the moist or humid air around the plant is quickly replaced by less humid air allowing the plant to release even more water into the atmosphere. When wind movement around a given plant increases, the rate of transpiration is bound to increase. A. This occurred because wind increases transpiration rates. Glucose made in photosynthesis is then moved to all cells in phloem vessels for respiration. 6. what is the importance of transpiration. 2 Comments tiff. Transpiration rates depend on two major factors: 1) the driving force for water movement from the soil to the atmosphere and 2) the resistances to water movement in the plant. It is difficult, however, to determine the effect of individual factors strictly in the field condition, because in nature it is not possible to change one factor without changing other factors. Wind: Transpiration is more when the wind is blowing faster as water evaporates faster from the leaves. Transpiration is affected greatly by the environment factors such as temperature, light relative humidity, wind, and so on. This environmental factor affects transpiration by removing that thin moist layer of air, called boundary layer, which lies next to the surface of a leaf. What factors increase transpiration in plants? During dark, the stomata are closed, and hence transpiration hardly occurs at night. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. What is the purpose of transpiration in plants?
