How does light affect the rate of

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. The effect of light on germination and seedlings david batty explains this important aspect of growing from seed apparently it was custom in ancient egypt, before finally sealing the tomb, to leave a little pile of moistened corn near the sarcophagus. Biology - how light intensity affects the rate of photosynthesis 2110 words | 9 pages ¡v does the light intensity affect the rate of photosynthesis the investigation in this experiment i will investigate the affect in which the light intensity will have on a plants photosynthesis process. Hi, i’m doing a science experiment about the effect of coloured light on plant growth, i’m after some background information, can you please tell me out of clear light, red light, green light and blue light the order of growth of plant and why this is. Factors that affect the growth of moulds jackson kung'u the major factors affecting growth of mould are nutrients, temperature, light, aeration, ph and water activity.

Factors affecting rate of chemical reactions intensity of light the rate of some photochemical reactions, which occur in presence of light, increases with increase in the intensity of suitable light used with increase in the intensity, the number of photons in light also increases the solvent may affect the rate in many ways as. Light activates some of the reactant molecules producing free radicals since free radicals are very exited, therefore, they react immediately with other molecules to form products the concentration of reactants does not influence the rate of such reactions, so they are zero order reaction. A) light intensity, co2 concentration, and temperature are factors that determine the rate of photosynthesis b) light intensity has no effect on the rate of photosynthesis c) if the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease.

The effect of light colour on the rate of photosynthesis to what extent does the colour of light have on the rate of photosynthesis on cabo offers fair use policy. For example, the amount of light will affect the rate of photosynthesis if there is no light, there will be no photosynthesis as light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply as the rate increases, eventually another factor will come. Abstract this is an interesting experiment if you are 1) curious about insect metamorphosis and 2) patient you will need to set up different controlled environments for the chrysalides, and then check on them regularly as you wait for them to hatch. -at maximum rate more light intensity will have no effect and the rate will plateau because chlorophyll is saturated by light -different wave lengths have different affects on the rate how does the concentration of carbon dioxide affect the rate of photosynthesis. Medium light plants can grow in the 15-watt range, but higher intensities of light can promote faster growth rates high light plants require at least 20 watts per square foot of growing space, though higher intensities will further promote growth and flowering.

Light intensity is one of the factors that affect the rate of photosynthesis and that is what our experiment is based on: aim: in this experiment we shall investigate how the rate of photosynthesis (measured by the increased volume of oxygen) is affected by changes of light intensity in water plants. 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. As temperature increases, so does the rate of transpiration, opening the stoma (pores in the epidermis) for gas exchange and water vapor loss but if the light is too intense, or the soil too dry, the stoma close up in order to conserve moisture within the leaf.

How does light affect the rate of

I strongly suspect that the choice of bulb will make no noticeable difference in evaporation rate the total energy density striking the floor due to a 100 w bulb, even assuming that all of the energy is converted to light, is on the order of 120 $\mu \mbox{w}/\mbox{cm}^2$, which is tiny, and real bulbs are only on the order of 1% to 5% efficient, with most of the rest of the energy carried. The rate of photosynthesis increases at the lower intensities of light and decreases at its higher intensities when intensity of light is high, the temperature is higher and hence transpiration increases which leads to closing up of stomata and thus the photosynthesis decreases. 3 the factors affecting the rate of chemical reactions 3f the effect of light can light affect the speed of any reactions if it does, how does change the speed of a chemical reaction.

  • The rate of photosynthesis increases linearly with increasing light intensity (from point a to b on the graph) gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point b to c on the graph.
  • Gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point b to c on the graph) here a rise in light intensity has no affect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting.

Rate of photosynthesis under different wavelengths the rate of photosynthesis is affected by the different wavelengths of light a plant is exposed to because different pigments in chloroplasts absorb different wavelengths for use in photosynthesis. Bright light is a basic element of photosynthesis, but variations in the color of light have an effect on plants the entire spectrum of light hits the plant's leaves at the same time, but there are some colors that are known to cause higher amounts of photosynthesis than others. For a given setup, there is some intermediate optimal amount of light hitting your photosynthetic organism which maximises the rate of photosynthesis what matters to your question is (1) how the light intensity and distance affects the amount of light hitting your sample and (2) how the amount of. Light – stomata are triggered to open in the light so that carbon dioxide is available for the light-dependent process of photosynthesis stomata are closed in the dark in most plants very low levels of light at dawn can cause stomata to open so they can access carbon dioxide for photosynthesis as soon as the sun hits their leaves.

how does light affect the rate of Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, ph and intensity of light the photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. how does light affect the rate of Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, ph and intensity of light the photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. how does light affect the rate of Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, ph and intensity of light the photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants.
