Solution


Q.

Which of the following has proved helpful in preserving pollen as fossils                     [2018]
1 Pollenkitt    
2 Cellulosic intine  
3 Oil content   
4 Sporopollenin  

Ans.

(4)

Exine of pollen grain is made up of highly resistant fatty substance called sporopollenin, which is not degraded by any enzyme. It is not affected by high temperature, strong acid or strong alkali. Because of the sporopollenin, pollen grains are well preserved as microfossils.
