Name the seed with folded plumule leaves

The seed in which the plumule (the embryonic shoot) has folded leaves is the gram seed (Cicer arietinum), which belongs to the legume family (Fabaceae).

A gram seed is a dicotyledonous seed, meaning it contains two cotyledons. The seed is enclosed within a hard, protective seed coat. When the seed coat is removed, the main parts of the embryo become visible – the radicle (embryonic root), the plumule (embryonic shoot), and the cotyledons, which store food.

In gram seeds, the plumule appears as a small shoot situated between the two cotyledons. The characteristic feature is that the plumule consists of very tiny, folded leaves, which remain protected during seed development. These folded leaves later unfold and develop into the first true leaves when the seed germinates. The radicle, on the other hand, emerges first during germination and develops into the primary root system.

Thus, the folded structure of the plumule is a distinguishing feature of gram seeds and some other leguminous seeds. This adaptation protects the delicate embryonic leaves inside the seed until conditions are favorable for germination.

Therefore, the seed with folded plumule leaves is the gram seed.
