Question

The characteristic shown by monocots is :
A. I only
B. II only
C. I and II only
D. I and III only

Answer 1

Hint: Monocots are the plants that belong to angiosperms and have only a single cotyledon. One of the common examples of monocots is grass.

Complete answer: Monocotyledons are one of the two great groups of flowering plants or angiosperms. The characteristics of monocots are single cotyledon, parallel-veined leaves, and scattered vascular bundles in the stem with the absence of a typical cambium and adventitious root system.
In monocots, cambium is absent so secondary division is not observed so secondary xylem and secondary phloem are not formed.
Net like venation or reticulate venation is generally present in dicots.
The Taproot system is common in gymnosperms.

So, the correct answer is “Option A”.

Note: Characteristics of angiosperms are :
1. All angiosperms flower at some stage in their life cycle. The flowers are the reproductive organs for the plant, providing them with the means of exchanging genetic information.
2. The vascular system has true vessels in their xylem and companion cells in the phloem.
3. The ovules are enclosed in the ovary at the base of the megasporophyll.
4. Angiosperms are heterosporous which means they produce two kinds of spores microspores which are also known as pollen grains and megaspores. Angiosperms can survive in a variety of habitats including marine habitats.
