(example answer: tropical sage had the highest transpiration rate its physical characteristics include a high leaf surface area to overall plant ratio compared to tickseed, and its leaves have a rough textured surface compared to the horsetail. 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. Leaves that possess many hairs or pubescence will have larger boundary layers the hairs serve as mini-wind breaks by increasing the layer of still air around the leaf surface and slowing transpiration rates.
Overall, the fabric container trees across all species illustrated the highest quality trees, followed by those planted in plastic containers and the b & b minimal data was recorded for transpiration rates in 1996 and will be further investigated in 1997. Residual transpiration rates, epicuticular wax loads and leaf colours of 20 cultivars of pea (commercial varieties and bred, improved lines) were studied the residual transpiration rate varied between genotypes from 077 to 182 mg m −2 s −1 , while wax content varied between 019 and 041 g m −2. Linear relationship between the leaf area and transpiration rate of impatiens replicates ( n ) = 3 compared with the impatiens grown in cd40-cf, the impatiens grown in the cd40-ck had a significantly larger la and a higher tr ( p 005), and accumulated significantly higher concentrations of cd in the stems and leaves ( p 005. Transpiration rates increase in a plant when the stomata are openin desert plants, the stomata are very small but are almost alwaysopen they have the highest transpiration r transpiration rate depends on leaf (surface area )more the surface area of leaf more the transpiration will occur share to.
Introduction most of the water a plant absorbs is not used for a plant’s daily functioning it is instead lost through transpiration, the evaporation of water through the leaf surface and stomata, and through guttation, which is the loss of water from the vascular tissues in the margins of leaves. -- humidity: high humidity = decrease in transpiration because dry air makes diffusion of water out of leaf occur more rapidly-- wind: increases evaporation from leaves/increased transpiration rate because stomata will be open, water will evaporate causing continuous transpiration, and wind will increase temperature. Determination of the transpiration rate of different plant species within name: thomas neema student #: 200545388 tutor's name: dr w jankowitz duty station: nadeet june 2006 contents 1 introduction 11 objectives leaf was placed on the graph paper and its outline was drawn onto the paper the number of large (l cm2) squares within. Transpiration is the process by which plants absorb and distribute water through their roots and release water vapor through their leaves transpiration is the primary basis by which a plant sustains its life. When wind movement around a given plant increases, the rate of transpiration is bound to increase the wind movement causes a rapid replacement of moist air with drier air around the given plant, which is why the rate of transpiration inevitably increases.
-the species of plants with the highest transpiration rates are rubber plant, zebra plant, and dieffenbachia (from highest to lowest) since different species of plants live in different environment thus, they have different rates of transpiration also, different rates of transpiration are caused by different species of plants' abilities to adapt to different environments through evolution. The rate of evaporation of water from the air spaces of the leaf to the outside air depends on the water potential gradient between the leaf and the outside air various environmental factors, including those conditions which directly influence the opening and closing of the stomata, will affect a plant’s transpiration rate. Thus from very low transpiration rates to the highest obtainable, far from aif rising linearly with transpiration, there was no response in aw and similarly no response in relative on the relationship between transpiration rate and leaf water potential. 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. (online plant transpiration lab ) which species of plants that you tested had the highest transpiration rates why do you think different species of plants transpire at different rates the size of the plant (larger leaf surface area = more transpiration) the metabolic rate of the plant = plants with a higher metabolism have a higher.
The species of plants with the highest transpiration rates are rubber plant, zebra plant, and dieffenbachia (from highest to lowest) since different species of plants live in different environment thus, they have different rates of transpiration. Leaf and highest transpiration rates essay biology assignment transpiration rates between exotic vs native plants in this investigation we will be looking at transpiration the topic we will be focusing on is transpiration rates between native plants as well as exotic plants we will be experimenting with 2 native plants as well as 2. Transpiration: how does leaf surface area affect the movement of water through a plant introduction water moves through the plant because the concentration of water is highest in the roots of a plant and lowest in the leaves transpiration, or loss of water from the leaves due to evaporation, helps the transpiration rate of a plant (or. When the leaves were not subject to wind, the average transpiration rate per minute per m2 was 016 ml when a fan was put on the leaves, the transpiration rate increased by 03 ml, making the average transpiration rate per minute per m2 119 ml.
Indeed, high wind speed may cause stomata to close a) because of the high rate of transpiration leading to water stress but also b) (when photosynthesis rate is high) gentle breeze can bring more co 2 close to the stomata, increasing the diffusion of co 2 into the leaf, causing guard cells to become less turgid. Rate means something happened per unit time so, rate of transpiration would be transpiration occured per unit time if you are calculating only about one leaf, its fine but if you want to carry out an experiment with different size of leaves, u must think about the surface area of the leaves. Leaf structure, type of stomata, root and shoot ratio, etc, may also affect the rate of transpiration importance of transpiration transpiration is a very important process not only for the plant but also for the environment.
