Question

Mango is a monocot plant.
A. True
B. False

Answer 1

Hint: Dicot plants are the angiosperm with two cotyledons in their seeds that is a characteristic feature of dicot plants.

Complete answer:
Angiosperms or flowering plants are divided on the basis of the nature of the embryo in the seed into Monocotyledonous and Dicotyledonous plants. Dicots consist of plants having seeds with two cotyledons However, monocots involve the plants having seeds with only one cotyledon. Examples of the dicot plants are mango, neem, sunflower, apple, plums, etc.

Characteristic of the dicot plants –
- Dicot plants have an embryo with two cotyledons. The Embryo axis has two ends, one which forms the shoot tip known as plumule and the lower tip that forms the root tip called as radical.
- Cotyledons usually have a swollen appearance which acts as a food reserve for the developing plantlet.
- Dicot's plants have three furrows or pores in its pollen.
- Leaf veins in dicots generally have various auxiliary veins that reticulate between the major veins.
- Dicots have tap root systems with primary roots, which are thick for long extension and to penetrate deeply.
- During secondary growth, the diameter of the dicot stem increases and produces wood and bark.

So, the correct answer is ‘false’.

Note: In leaf veins, reticulate venation is the characteristic feature of the dicot plants however parallel venation is of monocots. But due to exception, some of the dicot plants also show parallel venation such as Calophyllum, Corymbium and some of the monocot’s plants show reticulate venation for example Alocasia, Smilax, etc.
