NEETBotanyBiological Classification
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In Whittaker's Five Kingdom classification, Chlamydomonas and Amoeba were brought together in Kingdom Protista. Reason (R): The shift in classification criteria to include cell structure and body organisation grouped all unicellular eukaryotes together, regardless of the presence or absence of a ce
Options
- ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
- BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
- CAssertion (A) is true but Reason (R) is false
- DAssertion (A) is false but Reason (R) is true
Correct answer
A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
Step-by-step solution
Assertion (A) is true because R.H. Whittaker's Five Kingdom classification placed all single-celled eukaryotes, including Chlamydomonas (previously placed in algae within plants) and Amoeba (previously placed in the animal kingdom), into Kingdom Protista. Reason (R) is true and correctly explains the assertion. Earlier classification systems relied heavily on the presence or absence of a cell wall, separating these organisms. Whittaker's system used cell structure (prokaryotic vs eukaryotic) and body organisation (
