Question

find odd man out give reasons testa,tegman,hilum,endosperm

Answer 1

Testa- testa. (Science: plant biology) Outer covering of a seed, also called the seed coat, derived from the integument of the ovary.
Tegman-tegmen (plural tegmina) (biology) A covering or integument, usually referring to a thin layer or membrane in an organism. (botany) An integument such as the inner membrane of the coat of a seed. (anatomy) A covering such as the thin layer of bone in the roof of the middle ear of mammals.
Hilum-In botany, a hilum is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus. On a bean seed, the hilum is called the "eye". For some species of fungus, the hilum is the microscopic indentation left on a spore when it separates from the sterigma of the basidium. 
Endosperm-Endosperm, tissue that surrounds and nourishes the embryo in the seeds of angiosperms (flowering plants). In some seeds the endosperm is completely absorbed at maturity (e.g., pea and bean), and the fleshy food-storing cotyledons nourish the embryo as it germinates.
So tegman is your answer i think✔
