Select the option which correctly depicts the functions of parts X,Y and Z

Options

A. `{:(X,Y,Z),("Dark reaction","Light reaction","Cytoplasmic inheritance"):}`
B. `{:(X,Y,Z),("Light reaction","Carbohydrate synthesis","Carbohydrate storage"):}`
C. `{:(X,Y,Z),("Light reaction","Carbohydrate storage","Carbohydrate synthesis"):}`
D. `{:(X,Y,Z),("Carbohydrate synthesis","Carboyhydrate storage","Cytoplasmic inheritance"):}`

Answer

B

Explanation

Light reactions (or photochemical phase) of photosynthesis mainly occur on the grana thylakoids. Dark reactions (or biosynthetic phase) which involves synthesis of chrbophydrates by `CO_(2)` fixation, occur in the stroma (or matrix) of chloroplasts. The chloroplast matrix of higher plants stores starch temproality in the form of starch granules.
