Question

In five kingdoms classification given by R.H. Whittaker, how many kingdoms contain eukaryotes?

• A. Four
• B. One
• C. Two
• D. Three

Answer 1

Answer: (A)

• Five kingdom classification was proposed by R.H. Whittaker in 1969 and the five kingdoms are Monera, Protista, Fungi, Plantae and Animalia.
• The classification was done based on certain criteria and one among these criteria was the complexity of cell structure, i.e., prokaryotic or eukaryotic cell. Based on that, all four kingdoms except Monera have eukaryotic cells.

Hence, the correct option is 'A'.
