• C. tap roots
• D. nodulated roots

Answer 1

The correct option is C

tap roots

The correct option is option C.

Explanation of correct option:

Option C:

1. Plants absorb water, minerals, and essential nutrients from the soil through roots.
2. Roots are essential for anchoring the plant with soil.
3. The tap root system is seen in the Mustard plant
4. In the Tap root system, the primary roots grow inside the soil and bear lateral roots called secondary roots, and tertiary roots.

Explanation of incorrect options:

Option A:

1. Fibrous roots are seen in monocotyledon plants such as wheat where the primary are replaced by a large number of roots originating from the stem.

Option B:

1. Adventitious roots are seen in Banyan trees in which the roots arise from other parts of the plant than from radicles.
2. The adventitious root system in plants such as Monstera, grasses, and Banyan tree provides proper support to the plant parts and helps in the absorption of water and minerals from the soil.

Option D:

1. Nodules are the small outgrowths on the roots of leguminous plants.
2. The roots of leguminous plants such as sweet pea, Alfafa, garden pea, etc form nodules when infected with the bacteria Rhizobium.
3. The nodule formation is the symbiotic relationship between leguminous plants and Rhizobium bacteria for fixing atmospheric nitrogen into its usable forms.
4. The bacteria have the nitrogenase enzyme that combines atmospheric nitrogen with hydrogen to form ammonia, which can be utilized by plants for the synthesis of organic compounds.

Final Answer: The type of roots present in the mustard plant is tap roots.
