Question:
Roots of which plant contains a red pigment which have affinity for oxygen
Roots of which plant contains a red pigment which have affinity for oxygen
Updated On: Jun 23, 2024
- Carrot
- Soyabean
- Mustard
- Radish
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Leguminous plants develop root nodules, which house a red pigment known as leghemoglobin. This pigment functions as an oxygen carrier, regulating the molecular oxygen levels within the nodule's environment to keep them low. Soybeans are an example of leguminous plants.
So, the correct option is (B): Soyabean

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Concepts Used:
Root
A Root refers to the vascular part of any plant which is pinpointed or discovered at the lowest level and is entirely responsible for connecting the plant with the soil. It absorbs water (H20), minerals, nutrients, etc., and further feeds the plant for its development. Roots are also responsible for acting as the repository for food and nutrients of the plant.

Characteristics of Roots:
- Roots are homogeneous in nature due to their potential to work towards producing similar organs like secondary or tertiary roots from the pericycle.
- Roots can be examined as positively Geotropic and Hydrotropic but negatively Phototropic.
Functions of Roots:
- The roots are in charge of providing a systematic connection to the different parts of the plant.
- It is also accountable for the storage of the reserved food material and the synthesis for the growth of the plant.
