Answer 1

Answer:

Each seed is attached to the placental tissue on the fruit suture by a stalk called the funicle. The funicle is narrow at the placental end but widens into a disc where it joins the seed. When the mature seed is detached the broad end of the funicle leaves a scar on the seed called the hilum. Next to the hilum is a pinhole opening on the seedcoat which is the micropyle.

If the seed is’ soaked, wiped and then squeezed, water is seen to ooze out of this micropyle. The seed is covered by the tough seedcoat of a light colour. This tough seedcoat is the testa.

The tegmen, which is delicate and completely adherent to the inner side of the testa, is not distinguishable in the mature seed. On opening the seedcoat the kernel is obtained. The kernel in dicotyledonous exal­buminous seeds is the embryo. In it the two fleshy cotyledons are very conspicuous. These arc fleshy as all the nutrients required by the growing seedling in the first few days are kept stored here.

The two cotyledons are hinged to an axis (tigellum) so that they open out like a book. The tigellum represents the axis of the future plant. One end of the tigellum is pointed and protrudes out of the cotyledons
