Answer 14

Which one was??

Answer 15

Sporopollenin is the tough resistant protective biopolymer that coats the outer walls of the spores released by the sporophyte generation.

Answer 16

it was B.

Answer 17

That answer is wrong!! Sporopollenin is a major component of the tough outer (exine) walls of spores and pollen grains. It can withstand high temperates and no acid or enzyme is known that can degrade sporopollinin and this is accounted for presevation of the plant diversity and makes sure the continuity of plant in adverse conditions.

Answer 18

i have no clue they say it is B.It forms the spore wall, resistant to degradation by enzymes and chemicals, thus protecting the spores.
