After fertilization, the outer and inner integuments of an angiospermic ovule change into ________ respectively.

Step-by-step solution

After fertilization, the ovule develops into a seed and its integuments form the seed coats. The outer integument of the ovule develops into the outer seed coat, which is known as the testa. The inner integument of the ovule develops into the inner seed coat, which is known as the tegmen. Therefore, the outer and inner integuments change into the testa and tegmen respectively. Answer: testa and tegmen
