Question

The roots that originate from the base of the stem are:

• A. Fibrous roots
• B. Primary roots
• C. Prop roots
• D. Lateral roots

Answer 1

The Correct Option is A

To determine the correct type of roots that originate from the base of the stem, let's examine the different types of roots mentioned in the options:

1. Fibrous Roots: These roots are characterized by a cluster of thin, branching roots that emerge from the base of the stem. They are typical in monocotyledonous plants, such as grasses and cereals. Fibrous roots do not arise from the radicle but rather develop as a replacement for primary roots.
2. Primary Roots: This is the main root that develops directly from the radicle (embryonic root) of the plant. It is typically the first root to emerge from a seedling and can develop into a taproot system.
3. Prop Roots: These are adventitious roots that provide structural support. They grow above ground from the stem or branches and become embedded in the soil. An example is the roots of a banyan tree.
4. Lateral Roots: These roots emerge from the primary root or its branches. Their main function is to increase the root's surface area for better water and nutrient absorption.

The correct answer is Fibrous roots because they originate from the base of the stem and form a dense network of roots, unlike primary roots which develop from the radicle and are not specific to the stem base.

Thus, the roots that originate from the base of the stem are Fibrous roots.
