The substrate for photorespiration is ......... .

Which of the following organelles produces the simplest amino acid during photorespiration?

Plants that exhibit photorespiration are .......

Given below are two statements:
Statement $I$: In $C_3$ plants,some $O_2$ binds to $RuBisCO$,hence $CO_2$ fixation is decreased.
Statement $II$: In $C_4$ plants,mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration.
In the light of the above statements,choose the correct answer from the options given below:

$C_4$ plants are more efficient in photosynthesis than $C_3$ plants due to

In photorespiration,......... is not found.
