Dimorphism of chloroplast is found in
C3 - plants
C4 - plants
CAM plants
Both (b) and (c)
B.
C4 - plants
C4 plants have Kranz anatomy. The chloroplasts of the mesophyll cells are smaller and have well developed grana, while the chloroplasts of bundle sheath cells are agranal, ie, dimorphic chloroplasts are found in C4 plants.
The order of occurrence of the cytochromes in the F1 particle is
cyt-b, cyt-c, cyt-a-cyt a3
cyt-c, cyt-b, cyt-a-cyt a3
cyt-a, cyt-b, cyt-c-cyt a3
cyt-a3, cyt-a, cyt-c-cyt b
