Photorespiration
BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337345 Given below are two statements:
Read the Statement - A and Statement - B carefully to mark the correct options given below:
Statement A :
In \(\mathrm{C}_{3}\) plants, some \(\mathrm{O}_{2}\) binds to RuBisCO, hence \(\mathrm{CO}_{2}\) fixation is decreased.
Statement B :
In \(\mathrm{C}_{4}\) plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration.

1 Both Statement A and Statement B are
true
2 Both Statement A and Statement B are
false
3 Statement A is true but Statement B is
false
4 Statement A is false but Statement B is true

337346 Why productivity and yields are better in \({C_4}\) plants?

1 It lacks photorespiration and don’t tolerate high temperature
2 It shows photorespiration and can’t tolerate high temperature
3 It lacks photorespiration and shows tolerance to high temerature
4 It shows photorespiration and tolerates high temperature.

337347 The correct sequence of cell organelles during photorespiration is

1 Chloroplast → golgicomplex → mitochondria
2 Chloroplast → rough endoplasmic reticulum → dictyosomes
3 Chloroplast → peroxisome → mitochondria
4 Chloroplast → vacuole → peroxisome
