Question

A nutritive inner region of integument is?

• A. Amphithecium
• B. Endothecium
• C. Endothelium
• D. Endostomium

Answer 1

Answer: (C)

Endothelium

In some plants, which have unitegmic and tenuinucellate ovules, nucellus degenerates at an early stage of ovule development. In such cases, the innermost layer of the integument becomes specialized and forms a tissue around the embryo sac that performs the nutritive function for the embryo sac. This specialized tissue is called the Endothelium. Therefore, a nutritive inner region of the integument is Endothelium.

So, the correct answer is C
