Question

The microscopic pollen grains of the past are obtained as fossils. Mention the characteristics of pollen grains that make it happen.

• A. Intine is made up of sporopollenin
• B. Exine is made up of sporopollenin
• C. Both intine and exine are made up of sporopollenin
• D. None of the above

Answer 1

The correct option is B Exine is made up of sporopollenin

The microscopic pollen grains of the past are obtained as fossils because the pollen grains are covered by two protective layers, intine, and exine. The exine is made up of sporopollenin, sporopollenin is more resistant and It is chemically very stable and is usually well preserved in soils and sediments. So it can remain as such for millions of years.so, the correct answer is 'Exine is made up of sporopollenin'.

So.the correct answer is 'Exine is made up of sporopollenin'.
