Seed coat-ovary wall association is not correct.
The seed coat originates from the maternal tissue, that is, the integuments. It is one of the three components of a plant seed, in supplementation to the embryo and the endosperm. The aim of the seed coat is to safeguard the seed from temperature-related, physical or water destruction. It is a protective outer covering of the seed.
On the other hand, the ovary wall refers to the wall of the ovary of a flower that ultimately develops into a pericarp or fruit wall.
This arrangement of leaves benefit the plant by allowing the light from the sun to all parts of these trees. Having larger leaves above, will block sunlight to reach the lower part of the tree. Hope this answers the question. Have a nice day.
