Question

An example of dicotyledonous plant from the following is
A. Maize
B. Rice
C. Bean
D. Barley

Answer 1

Hint: The leaves of the dicotyledonous plants have reticulate venation, and flowers have a trimerous arrangement of flower petals.

Complete answer:
Dicotyledonous plants can be defined as the plants whose seeds consist of two cotyledons. These are the angiosperms that have a true vascular bundle. The root system of the plant is the taproot system. The seeds of the plant can be split into two equal halves. The common examples of dicotyledonous plants are bean, gram, apple, and mango.

Angiosperms are of two types, and these are monocotyledons and dicotyledons.
1) Monocotyledons can be defined as the plants whose seeds consist of single cotyledons. The seeds of monocotyledons are also called grains.
2) Monocotyledons consist of the fibrous root system. The leaves of the plant consist of parallel venation. The flowers of the monocotyledons consist of the pentamerous arrangement in the flower petals
3) Some common examples of monocotyledons are maize, wheat, rice, and barley.
4) The vascular bundles in the dicotyledon plants have a ring-like arrangement, whereas vascular bundles are scattered in the stem and root.
5) The monocotyledons and dicotyledons can be identified visually by observing the pattern of the leaf.

Hence, the correct answer is option (C).

Note: The dicotyledon plants are different from the monocotyledon plants on the basis of the number of cotyledons, types of roots, and venation pattern of the leaf. Dicotyledons consist of the reticulate venation, whereas monocotyledons consist of parallel venation.
