The correct option is B

two cotyledons


The correct option is B.

Explanation of the correct option.

  1. Cotyledons are structures that are present in a seed. They provide nutrition to the growing embryo and perform photosynthesis at the initial stage of plant development.
  2. Dicotyledon plants are those that produce seeds with two cotyledons.
  3. For example, gram.
  4. Thus, gram seeds have two cotyledons.

Explanation of the incorrect options.

Option A:

  1. One cotyledon is present in a monocot plant.
  2. For example, maize.

Option C:

  1. Plants with three cotyledons are called tri cotyledons.
  2. Gram seed has two cotyledons and, thus, a dicot.

Option D:

  1. Few plants do not have cotyledons as they form spores instead of seeds.
  2. For example, ferns.

Gram seed has two cotyledons and is classified as a dicotyledonous plant.
