Question

Given below is a diagram of T.S. of a monocot seed with parts I, II & III labelled:

Choose the option where parts I, II and III are identified correctly.

Options

• I - Pericarp, II - Endosperm, III - Scutellum

• I - Pericarp, II - Endosperm, III - Coleorhiza

• I - Scutellum, II - Pericarp, III - Scutellum

• I - Coleorhiza, II - Scutellum, III - Pericarp

Answer 1

I - Pericarp, II - Endosperm, III - Coleorhiza

Explanation:

The pericarp, endosperm, and coleorhiza are parts I, II, and III, respectively. The pericarp, which typically forms the fruit wall, fuses with the seed coat in monocot seeds. The nutritive tissue that feeds the growing embryo is called the endosperm. The radicle and root cap of the embryonal axis are covered by the coleorhiza, an undifferentiated sheath.
