Question
One of the most resistant biological material present in the exine of pollen grain is?
APectocellulose
BSporopollenin
CSuberin
DCellulose
Medium Open in App Solution Verified by Toppr
Correct option is B)
Outer layer (exine) of pollen grain is made of a highly resistant substance called sporopollenin. Sporopollenin is not degraded by any enzyme. It is not affected by high temperature, strong acid or string alkali. Because of sporopollenin, pollen grains are well preserved as fossils.
