Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A plant in your garden avoids photorespiratory losses, has improved water use efficiency, shows high rate of photosynthesis at high temperatures and has improved efficiency of nitrogen utilisation. In which of the following physiological groups would you assign this plant?
A
C4
B
CAM
C
Nitrogen fixer
D
C3
Explanation: 

Detailed explanation-1: -Final answer: A plant in your garden avoids photorespiratory losses, has improved water use efficiency, shows high rates of photosynthesis at high temperatures, and has improved the efficiency of nitrogen utilization. This plant belongs to the C4 group.

Detailed explanation-2: -Cellular respiration is a positive term which is very important for survival but photorespiration is a negative term because it leads to loss to the method of using light energy in photosynthetic organisms to fix carbon for subsequent carbohydrates.

Detailed explanation-3: -Photorespiration replaces carbon dioxide in the Calvin cycle with oxygen. As a result, sugar is not created since carbon is not fixed, and the process uses more oxygen. As a result, photorespiration reduces photosynthetic output.
