Question 12 |
The correct sequence of cell organelles during photorespiration is
Chloroplast, – peroxisome, – mitochondria | |
Chloroplast, – vacuole, – peroxisome | |
Chloroplast, – Golgibodies, – mitochondria | |

nice questions but quite tough
very much effective!
one of the question is wrong…. in photorespiration the sequence is chloroplast-peroxisome-mitochondria
it was just briliant
Because co2 trapped by c4 plants will be utilised in photosynthesis which otherwise is lost in c3 plants while performing photorespiration
