Question

define sporopollenin

Answer 1

hey buddy,

sporopollenin is a highly highly resistant (aka inert ) organic material (bio polymer) .

(polymer is nothing but a compound made of large number of similar units bonded together)

it is a notable component of the tough outer walls of plant spores and pollen grains.

it can stand extreme cases like high temperatures and acids and desication .

this property makes the pollens durable and well protected / preserved .
