(iii) Stoma lamellae membranes possess PS I only whereas grana lamellae membranes possess both PS I and PS II.
A. i only
B. ii only
C. iii only
D. i,ii and iii

Answer 1

Correct Answer - C
PSI is involved in both cyclic and non-cyclic photophosphorylation PS II is involved only in non-cyclic photophosphorylation PS II is present in the aprressed (inner) part of grana thylakoids, PS I is located in the non-appressed (outer) part of grana thylakoids as well as stroma thylakoids
