Question

Differentiate between monocot and dicot with three examples. Draw necessary diagrams.

Answer 1

Hint: Comparison is done on basis of definition, leaves, vascular bundle, root system, stomata, secondary growth, secondary cambium, vascular bundles in stem, venation in leaves.

Complete answer:

Basis:	Monocot	Dicot
Definition:	Plants having one cotyledons in seeds are monocots	Plants which have two cotyledons in seeds are dicots.
Venation:	Monocot leaves have parallel venation.	Dicot leaves have reticulate venation
Stomata:	Stomata are present on both the upper and lower epidermis of leaves	Stomata are present more on the lower surface of leaves
Root system:	Monocots tend to have fibrous root system	Dicots have tap root system
Leaves:	Dorsiventral leaves are present	Isobilateral leaves are present
Stem:	Vascular bundles are scattered in stem	Vascular bundle are present in ring in the stem
Secondary cambium:	Secondary cambium is absent in monocots	Secondary cambium is present in dicots
Secondary growth:	Secondary growth does not occur in monocots	Secondary growth occurs in dicots
Examples:	Examples: Sugarcane, wheat, rice etc	Examples: Mango, tomato, lettuce etc.

Note: Plants with one cotyledon are monocot and plants with two cotyledons are called dicot. You can also mention that the floral parts of monocot are in multiples of three and dicot is four or five.
