how does water affect the rate of photosynthesis

If the plant does not have enough water, the plant's stomata will shut and the plant will be deprived of CO², and thus lower photosynthesis rate. Lower photosynthesis rate in a usual effect of water stress in plants and has been attributed primarily to stomatal limitation and secondary to metabolic impairment.

How do Different Leaves Affect the Rate of Photosynthesis? ... Based on your data, how does a decrease in temperature affect the rate of photosynthesis? Water, Light and Temperature are the main environmental factors that will affect photosynthesis, along with availability of CO2. In the winter trees lose leaves. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase. Yes, it does. Water stress causes the stomata to close, thus reducing the availability of CO 2.It also causes the leaves to wilt, reducing the surface area for photosynthesis. It gets energy from absorbed photons and uses … If concentration of water decreases, the rate of photosynthesis decreases.

Photosynthesis does not take plate in cells which lack oxygen. On a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are rarely covered in discussion of this topic. Result of Photosynthesis in Plants. The chloroplasts in plants use water, sunlight, nutrients to get ATP.

The End! It is difficult in normal lab conditions to prove that water directly affects photosynthesis unless a heavy isotope is used to trace the path of water.

Water also controls the opening and closing of stomata. Water affects the rate of photosynthesis indirectly. 5. Carbon dioxide concentration will directly affect the rate of photosynthesis as it is used in the photosynthesis reaction. Photosynthesis is an important biochemical pathway involving the production of sugar (glucose) from light, water and carbon dioxide and releasing oxygen. An increase in the amount of water leads to the increase in the amount of photosynthesis. It decreases the rate of photosynthesis because plants need water in order to do photosynthesis. These include: the rate of oxygen. The limiting effect of water is indirect. The rate of photosynthesis is related to concentration of carbon dioxide, temperature and light intensity. It is released into the air. Result of Photosynthesis in Plants. The respiration of the plant will increase, though, which means it will need more carbon dioxide and water to maintain itself at higher temperatures, even though it will only be growing at its maximum rate.

It reduces the rate of photosynthesis. … The limiting effect of water is indirect. That temperature is considered the optimum for many plants, and photosynthesis will not increase no matter how the temperature does. a. Temperature: 25°C b. Share Flipboard Email Print Chlorophyll in plant leaves converts carbon dioxide and water into the products glucose and oxygen. Controlled variables - the size of the pondweed, the volume of water used and its temperature. The environmental factors include light, availability of CO2, temperature, soil, water and nutrient supply apart from age of leaf, leaf angle and leaf orientation. The main variables which affect photosynthesis are light, water, CO 2 concentration and temperature. Photosynthesis, the process by which plants create their food, can be affected by changes in pH within the leaves.
