STRUCTURE OF A SEED.
What is the structure of a seed?
A typical seed consists of a seed coat enclosing an embryo.
The seed coat is the outer covering which, in most seeds, is made
up of the two layers, an outer testa and inner one, the legmen.
The testa is thick; the tegmen is a transparent membrane tissue.
The two layers protect the seed bacteria, fungi and other organisms whk may damage it.
There is a scar called hilurn on one part of the seed.
