BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337043 Carbon dioxide enter photosynthesis through

1 PS I

2 Biosynthetic phase

3 Light reaction

4 PS II

Explanation:

Carbon dioxide enters in the carboxylation step of $C_{3}$ cycle during dark/ biosynthetic phase.

BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337044 Statement A :
The plants in which first product of $C O_{2}$ fixation is a $C_{3}$ acid (OAA) is called $C_{3}$ pathway and the plants in which first product was a $C_{4}$ acid (PGA) is called $C_{4}$ pathway
Statement B :
Calvin pathway occurs in most of the photosynthetic plants

1 Statement-A is correct but Statement-B is incorrect

2 Statement-A is incorrect but Statement-B is correct

3 Both the statements are correct

4 Both the statements are incorrect

Explanation:

Those plants in which the first product of $C O_{2}$ fixation is a $C_{3}$ acid (PGA), i.e., the $C_{3}$ pathway, and those in which the first product was a $C_{4}$ acid (OAA), i.e., the $C_{4}$ pathway. The Calvin pathway occurs in all photosynthetic plants; it does not matter whether they have $C_{3}$ or $C_{4}$ (or any other) pathways.

BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337045 PGA as the first $C O_{2}$ fixation product was discovered in photosynthesis of

1 Bryophyte

2 Gymnosperm

3 Angiosperm

4 Alga

Explanation:

Melvin Calvin made a study using 14C in alga-Chlorella in the photosynthetic $C O_{2}$ fixation and they were able to identify it as 3-carbon compound PGA-phosphoglyceric acid.
