Vedclass · Answer

(A) The sporoderm (pollen wall) consists of two main layers: the inner intine and the outer exine. The intine is composed of pectin and cellulose (pectocellulosic). The exine is composed of sporopollenin,which is one of the most resistant organic materials known. Thus,the assertion is correct as the sporoderm layers are protected by the highly resistant sporopollenin. The exine is further differentiated into an outer layer called the ektexine and an inner layer called the endexine. Therefore,both the assertion and the reason are correct,and the reason provides a structural description of the exine,which is part of the sporoderm.

$A$: In sporoderm,the pectocellulosic layer is surrounded by sporopollenin.
$R$: Exine is differentiated into outer ektexine and inner endexine.
