Answer 2

Answer:

Testa and tegmen of the seeds coat represent two layers of dried integuments.

Explanation:

The ovule maturation leads to the developmental changes in integuments in form of reduction and disorganization of the thickening. The ovules are covered with two layers of integuments. The outer integument is called as testa while inner integument is called as tegmen. The seeds are developmentally matured ovules containing two integument layers. The seed coat is developed from integuments which protect the embryo from mechanical injuries and desiccation. On the basis of development seeds are either bitegmic or unitegmic. Bitegmic seeds develop testa from outer integument and tegmen from inner integument while only single integument develops in unitegmic seeds.
