Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of model organisms in plant genetics.
Step 2: Detailed Explanation:
Arabidopsis thaliana is a model plant species for genetic studies.
It has:
- Small genome (125 Mb).
- Short generation time (6 weeks).
- Easy transformation.
- Many genetic and genomic resources.
Chlorella (B): A green alga (not a plant model).
Garden pea (C): Used by Mendel, but not a modern model organism.
Alfalfa (D): Not a model organism.
Thus, Arabidopsis is the model plant.
Step 3: Final Answer:
Thus, Arabidopsis is a model plant species, which corresponds to option (A).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
