Hint: The prefixes ‘mono’ and ‘di’ refer to the numbers one and two respectively. If two fresh leaves appear in a germinating seed of a dicot plant.
Complete answer: Cotyledons are the embryonic leaves in seed-bearing plants. These are the first leaves that appear from a germinating seed.
The seed-bearing or flowering plants can be classified based on various characteristics.
Their classification may be based upon the following:
1) cotyledon structure,
2) flower and vascular tissue arrangement, and
3) pollen grains.
If a single cotyledon appears in a germinating seed, the plant is said to be monocot or monocotyledonous. In these plants, the veins run parallel to the length of leaves, and the flowers are arranged in three-six fold symmetry.
If two cotyledons appear in a germinating seed, the plant is said to be dicot or dicotyledonous.
These plants have a whorl like a flower arrangement and their leaves have networks of veins.
So, the correct answer is B. Dicots.
Note: Biennial refers to the type of plants that complete their life cycle within two growing seasons. Annuals refer to the plants which have a complete life cycle.
