What is the main characteristic of dicot seeds?
1 Answer
The ovules after fertilisation develop into a seed. The main characteristic of a dicot seed is that it contains two cotyledons.
Explanation:
The outer most covering of a dicot seed is the seed coat. It has two layers the outer testa and the inner tegmen.
Hilium is a scar on the seed coat through which the developing seeds were attached to the fruit.
Near the hilium lies a small pore called the micropyle.
The embryo lies within the seed coat and consists of a embryonic axis and two cotyledons. The cotyledons are often fleshy and full of reserve food materials.
The radicle and plumule are present at the two ends of the embryonal axis.
Certain seeds have an endospermic tissue that contains stored food for the embryo. Examples of endospermic seeds are castor, cotton, and coffee.
Non endospermic seeds like bean, gram, and pea do not have a stored food reserve.
