Factors that affect the rate of photosynthesis

what are some factors that affect photosynthesis

That these protoplasmic factors appear to be enzymatic is indicated by the fact that the capacity for photosynthesis is lost at temperatures above 30°C or at strong light intensities in many plants even though cells are green and living. The most plausible reasoning for this would be that the spinach leaf was thinner than both of the others; which means there is a shorter distance for the carbon dioxide to travel. Different plants show different rate of 1 photosynthesis under different quality of light. The rate of photosynthesis will begin to slow and then stop. The idea to get across is that different conditions will be most important on different occasions.

When, carbon dioxide concentration is reduced, there comes a point at which illuminated plant parts stop absorbing carbon dioxide from their environment. A brief account on these three aspects is given as follows: Factor 4. Leaves of tree often show developmental adaptions to different conditions. Even small amount of this energy, may supplement light energy. Temperature : Like all chemical reactions, lower temperat … ures speed down the rate. A plant cannot survive for long at compensation point because there is a net loss of organic matter due to respiration of non green organs and respiration in dark.

Optimal Conditions for Algae Growth Most algae thrive and multiply in water with high pH levels ranging between seven and nine. Neutral or lower water pH decreases the growth of algae. Some of these factors are intrinsic, determined genetically or developmentally. In order to ensure that the lab has more accurate data, it would be wise to used fresh leaves. Chemical Compounds : Many different kinds of chemical compounds have direct or indirect effect upon the rate of photosynthesis. Rate of the process varies with the light intensity, temperature, and concentration of carbon dioxide in the plant's atmosphere. They need water to support the plant to face the sun as well as a raw material of photosynthesis.

Enzymes work better in warm conditions up to about 50ºC when enzymes start to be destroyed by heat. Algae grow fast in warm temperatures and water and when there is a lot of organic material in the water. If I had turned the security lights on my house on, the plants in my garden might possibly have photosynthesised faster. At low temperatures the enzymes responsible forphotosynthesis have very little energy so the rate ofphotosynthesis is very slow. Some woodland plants are known as shade plants because they can photosynthesis more efficiently in dim light than other species. The hydration of protoplasm is essential. The inhibitory effect is primarily attributed to increased dehydration of protoplasm and also stomatal closure.

what are some factors that affect photosynthesis

Photosynthesis is the conversion of light energy to chemical energy; the production of carbohydrates from carbon dioxide and water in the presence of chlorophyll by using light energy. In what ways are the two response curves different, and why? Opening and closing of stomata is controlled by specialized cells called guard cells. But water scarcity affects photosynthesis indirectly. The poinsettia leaves consistently had 0 leaves floating with one exception and the jasmine only ever had 1 leaf disk floating. Less than 1% of the water absorbed by a plant is used in photosynthesis.

You can both ask and answer questions, and teachers will get back to you. Select your answer by clicking on the appropriate letter. If it gets too hot the enzymes begin tolose their shape denature. Algae draw carbon dioxide from the water to utilize during photosynthesis, promoting cell growth. The rest of the tree, bark etc. Light supplies energy for the process.

Rate of the process varies with the light intensity, temperature, and concentration of carbon dioxide in the plant's atmosphere. Some woodland plants are known as shade plants because they can photosynthesis more efficiently in dim light than other species. Light: The photosynthetically active region of the spectrum of light is at wavelengths from 400-700 nm. With the increase in C0 2 concentration, the rate of photosynthesis increases provided other factors are not limiting. By on June 2, 2017 in Factors Affecting Photosynthesis A limiting factor limits the rate at which a process can take place. The shorter distance had the best results out of all the trials, most probably because of the closer proximity of the light. Properties of chlorophyll and carotenoid pigments are optimized for absorption of blue and red light.

For example, on bright sunny days the carbon dioxide concentration of the atmosphere is usually the limiting factor, not light intensity. Photosynthesis is essentially the reversal of cellular respiration, and provides the life sustaining organic substances that our bodies need to survive Marne, Markley and Pecha, 2004. Unsurprisingly, many crops such as tomatoes and lettuces give much higher yields when grown in greenhouses. If you would like to modify the video, please contact us: info fuseschool. If the pH is too acidic or basic, enzymes will … be denatured which means they will change shape and not be able to catalyze reactions as well or entirely.

Tropical plants normally do not photosynthesize below about 5°C. The constants would be the amount of solution, temperature of the setting and solution, how large the leaf disks were, the number of leaf disks used and the amount of time under the light. Dehydration may even damage the micromolecular structure of the chloroplasts. No photosynthesis can take place in the absence of chlorophyll. On the other hand, algae in hot water springs may carry on photosynthesis at a temperature of 75 °C.

Under these circumstances, any further increase in the rate of photosynthesis can be brought about only if the light intensity is increased. The rate of photosynthesis depends on temperature the same way enzymes depend on temperature. Irradiance is the only true measure of the energy carried in light. The maximum absorption occurs in blue and red regions of the spectrum. While it is difficult to predict how guard cells will respond to conditions within the leaf chamber of the photosynthesis apparatus, what would you expect to happen if they close during the course of the experiment? In many plants, the optimum temperature is 25oC. The light allows for the process of photosynthesis to begin quicker because the light has a shorter distance to travel. These include size of stomata, their position, amount of intercellular spaces, thickness of epidermis and cuticles.
