Effect of light intensity on transpiration rates

• use a computer interface and a gas pressure sensor to measure the rate of transpiration • determine the effect of light intensity, humidity, wind, and temperature on the rate of transpiration of a plant cutting. Determine the effect of light intensity, humidity, wind, and temperature on the rate of transpiration of a plant cutting sensors and equipment this experiment features the following vernier sensors and equipment. • examine how environmental factors (light, wind, humidity, temperature, etc) affect the transpiration rate • learn to identify stomata and determine whether they are opened or closed. The effect of light intensity and temperature on the rate of photosynthesis aim the aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. Effects of light quality and intensity on diurnal patterns and rates of photo-assimilate translocation and transpiration in tomato leaves jason lanoue 1,2 , evangelos d leonardos 1 and bernard grodzinski 1.

Transpiration rate= 183 10-4ml/min/cm3 when the plant was subjected to higher intensity of light, the amount of water lost was different the data are represented in the following graph figure water loss with respect to time under lamp condition for potato. To measure the rate of transpiration we use a piece of equipment called a potometer a potometer measures how factors such as light, temperature, humidity, light intensity and wind will affect the rate of transpiration. Light intensity and transpiration' since the secondary effects of variations in light intensity through and with transpiration rates and a moisture supply .

In this investigation students look at the rate of water uptake by a shoot, due to transpiration, using a simple but effective potometer there are two main types of potometer used in schools – the mass potometer, which measures transpiration through the loss of mass, and the moving-bubble . Effect ofcolored light on stomatal opening rates of to the peak intensity of the light spectrum, and i is the energy light effects onstomatal opening in . Free an experiment to investigate the effect of light intensity on the rate of photosynthesis papers, how light and wind affect the rate of plant transpiration. The diffusion rate of water increases as the wind speed increases, so the transpiration rate too increases according to the speed of the wind 2 intensity of light. Light intensity, humidity, wind and availability of soil water can affect the rate of transpiration in plant when there is light, the guard cell will increase the size of the stomata thus transpiration is much greater in the light.

For example the lamps used to give the leaves the maximum possible light intensity in the experiment will also have the effect of slightly heating up the leaves this could cause the rate of transpiration to go up. Answer problem statement: how does the light intensity affect the rate of transpiration objective: to investigate whether light intensity affects the rate of transpiration. Light, specifically light intensity, is probably the most obvious among the environmental factors affecting transpiration in plants it has a controlling effect on the opening of the stoma through which water primarily escapes in gaseous state. In this experiment aim to investigate how wind, temperature and alight intensity affect the rate of a plant s transpiration hypothesis: i predict that if the wind speed temperature or light intensity increases the rate of transpiration will increase. The effect of wind on the transpiration rate of tomato scions was studied 1 under high relative humidity, winds decreased the transpiration rates with increasing light intensity under low .

Dependent variable: rate of transpiration (determined by mass measurements) one plant placed in a sunny location where it will receive light one plant placed in a shady location where it receives less light mass is used to measure the transpiration rates in each plant to see how it is affected by light intensity. Title: comparative analysis of the effect of light intensity on the transpiration rate of prunus domestica and tropaeolum peregrinum introduction: transpiration is the loss of water in plants, which occurs through the stomata or intercellular spaces, and in smaller amounts through the exposed walls of surface cells. Year 10 eei – plant investigation the following assignment presented is based on the information and outcomes of an experiment conducted by claire dunne, eilis brien and myself about the effects of light intensity, representing the three seasons of summer, spring, autumn and winter, on the transpiration rate of mangrove shoots. Significantly affect transpiration rates: species, light, temperature, humidity, of natural light intensity, it is not possible to equate results from growth chamber.

Effect of light intensity on transpiration rates

When observing the average transpiration rate between trials, the control and moderate ligth conditions were relatively equal, while there was a spike in transpiration rate for the third condition, high intensity light. The rate of transpiration is roughly proportional to the intensity of light the mode of action of light is both direct and indirect the increasing light intensity raises the temperature of leaf cells and thus increases the rate at which liquid water is transformed into vapors. Does the intensity of light have an effect on the rate of transpiration in common geranium plants light intensity = 5738 x̄ = 01971 s = 00187 as the light intensity increases, the rate of transpiration will remain the same because the stomata will either be open or closed depending on the absence of light and not by the amount of light.

How does light intensity affect the rate of transpiration the brighter the light the greater the rate of transpiration more stomata open allowing more carbon dioxide in for photosynthesis, more water will be lost. A potometer measures how factors such as light, temperature, humidity, light intensity and wind will affect the rate of transpiration the main type of potometer is the 'bubble' potometer shown in figure 519 .

Light intensity has an important role on rate of transpiration transpiration is greater in day light as it enlarges the size of stomata and more water is lost to atmosphere how does mist . How would it affect the rate of transpiration if only the top surface was covered how would it affect the rate of transpiration if only the bottom surface was covered also, i think i'm right in saying that increasing wind / applying a fan to plant leaves will increase the transpiration rate, but why. The effect of dark, light, fan, and mist on whole plant transpiration abstract: the purpose of this experiment was to test the effects of environmental variables on rates of transpiration using a controlled experiment.
