(b) Identify the given seed as monocot or dicot seed.
(c) What kind of germination takes place in this seed?​

Answer 1

Answer:

The outermost layer is formed by the fusion of the fruit-wall and seed-coat. The endosperm constitutes the upper one-third to the three-quarters of the grain. The endosperm has thin outer aleurone layer and and an inner part containing starch grains. The aleurone layer consists of proteins and fats. A shield-shaped single cotyledon is known as the scutellum. It is separated form the endosperm by the epithelial layer. The embryo is embedded in the scutellum. Its plumule is covered by a sheath called as the coleoptile and the radicle by the coleorrhiza.
