Effects of high temperature on photosynthesis and related

Apr 28, 2014 · Response of the photosynthetic rate to heat stress. To examine the effects of high temperature on poplar photosynthesis, we measured the dynamic Pn, Ci, Gs, Tr, and iWUE over a time course of high temperature treatment (0 h, 3 h, 6 h, 12 h, 24 h) (Figure 1A-E). At three hours, Pn, Gs, Tr and Ci were significantly lower in heat-treated plants than in control plants, but iWUE was significantly Effects of light and temperature on the photosynthesisThe effects of temperature on photosynthesis and metabolism of Posidonia sinuosa from Princess Royal Harbour during February, 1989. Vertical bars indicate standard errors. a) Respiration rate; b) Gross maximum primary production; c) Net maximum primary production at 24, 82 and 1020 J..UDOl m-2s-1; d) Initial slope of the P-1 curve {lslope); ef

Factors affecting the rate of photosynthesis

Plants can photosynthesise over a wide range of temperatures from 0°C to around 50°C. The optimum temperature for most plants is 15°C to around 40°C. Temperature affects the rate of photosynthesis How Does Temperature Affect Photosynthesis? eHowThat temperature is considered the optimum for many plants, and photosynthesis will not increase no matter how the temperature does. 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.

How does temperature affect the rate of photosynthesis?

photosynthesis in spinach leaves have an optimal temperature where it works best. The optimal temperature for the fastest rate of photosynthesis will fall between 2°C and 75°C, and more towards the 24°C water. The difference between the two temperatures will affect the amount of time it takes for the leaf disks to float. IGCSE Biology:2.19 understand how varying carbon dioxide Feb 12, 2013 · 2.19 understand how varying carbon dioxide concentration, light intensity and temperature affect the rate of photosynthesis Carbon dioxide If there is insufficient carbon dioxide a plant will not be able to photosynthesis to its full potential. Because there is less carbon dioxide- less reactant- there has to be less product being made.

Lab 5. Photosynthesis:Why Do Temperature and Light

mine how temperature and light intensity affect the rate of photosynthesis. You will therefore need a way to calculate a rate of photosynthesis. A photosynthesis rate can be calculated by measuring how much CO 2 a plant consumes or how much O 2 a plant produces over time using the following equation:Photosynthesis rate = change in CO 2 or O Lab 5. Temperature and Photosynthesis:How Does Lab 5. Temperature and Photosynthesis:How Does Temperature Affect the Rate of Photosynthesis in Plants? Introduction . All the colors that our eyes can see can be found in plants that live in the world. They include deep, bright reds to rich blues and purples.

Jan 02, 2016 · Affect of Heat on the Rate of Photosynthesis. There were only 5 discs in the hot water solution, and the rest ended up on the ceiling but it is still easy to see that the discs in hot water went through photosynthesis faster than the 10 discs in the room temperature water. Not only did the discs rise at a faster rate, but the first disc in the The effect of temperature on photosynthesisDec 06, 2010 · 6. High Temperature More Oxygen Produced by Photosynthesis Low Temperature Less Oxygen Produced by Photosynthesis 7. Rate of photosynthesis at differenttemperatures were measured by Counting the oxygen bubbles produced by photosynthesis

The temperature response of C3 and C4 photosynthesis

This review will synthesize our current understanding of temperature effects on the photosynthetic biochemistry, and how these effects determine the thermal response of whole-leaf photosynthesis in C 3 and C 4 plants. This understanding will then be used to evaluate the mechanisms by which plants acclimate to different thermal environments.IB QuestionbankAccept answers between 9 mol m2 s1 and 11 mol m2 s1. b. rate of respiration is increasing. c. rate increases as the temperature increases up to a point/40°C and then decreases. d (i). at low temperatures/between 25°C and 35°C the rate of photosynthesis increases and the rate of respiration is (approximately) constant;
