The effects of temperature on growth and photosynthesis of C3 and C4 in education

Photosynthesis, or photosynthetic assimilation, is a set of biochemical processes during which received light radiation energy is changed into energy of chemical bonds. To produce organic compounds, the photosynthesis uses as energy source only light energy and other sources of energy are CO2, mineral nutrients and water. The heat (infrared radiation) is one of the most important external environmental factors affecting plants. Too much of heat or its lack cause plant stress and influence all biochemical processes. Accordin, to the way of CO2 fixation, three types of photosynthesis can recognized- C3, C4 and CAM. Furthermore, C3 and C4 types of plants can be distinguished according to thein optimum temperature range, when C4 plants have optimum temperature ranges generally higher than C3 plants. Another differences between these types of plants consist in different physiological response to the changing climate, above all to the increasing concentration of atmospheric CO2 and simultaneously increasing temperature. The higher the concentration of CO2, the higher the rate of photosynthesis of C3 plants, whereas increased temperature increases the rate of photosynthesis of C4 plants. These different reactions of C3 and C4 plants on different environmental factors have consequences in a rate of net..
