Question

Give the differences between monocots and dicots.
A. Monocots: Seeds with one cotyledon. Dicots: Seeds with two cotyledons
B. Monocots: Seeds with two cotyledons, Dicots: Seeds with one cotyledon
C. Monocots: Leaves have parallel venation. Dicots: Leaves show reticulate venation
D. Both A and C

Answer 1

A flowering plant is divided into monocots and dicots. The cotyledon in a plant bearing seed is the leaf of an embryo and after germination, it becomes the first leaves of the seedling. Monocot and dicot plants are differentiated on the basis of four traits which are: stems, root, leaves, and flowers.

Complete step by step answer:
A flowering plant can either be monocot or dicot. In a plant bearing seed, a cotyledon is the leaf of an embryo and after germination, it becomes the first leaves of the seedling. Monocots (mono means one) are categorized when it is a single seed leaf and dicots (di means two) are categorized as it is a pair of leaves.
The difference between the monocots and dicots are given below:

Monocots	Dicots
The embryo of monocots have a single cotyledon	The embryo of doctors have a pair of cotyledons
In monocots, the leaves have parallel venation	In dicot, the leaves have reticulate venation
The monocots have a fibrous root system	The dicots have a tap root system
In monocots, the stem is fleshy and unbranched	In dicots, the stem is hard and branched

Therefore monocots have one cotyledon and dicots have two cotyledons. Leaves of monocots have parallel venation and dicot leaves have reticulate venation.
So, the correct answer for the above question is option (D).
Note:
A monocot flowering plant has a single cotyledon on the other hand a dicot flowering plant has a pair of cotyledons (two cotyledons). The leaves of a monocot plant have parallel venation whereas the leaves of a dicot plant have reticulate venation.
