Question

Which kingdom of the Whittaker classification is not well defined?

• A. Monera
• B. Protisa
• C. Animalia
• D. Fungi

Answer 1

Answer: (A)

• Whittaker's classification scheme recognizes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.
• Monera is a kingdom that contains unicellular organisms with a prokaryotic cell organization, such as bacteria. They are single-celled organisms with no true nuclear membrane.
• But after some studies it was found that some bacteria are chemically different, so the monera kingdom was separated into two new kingdoms- Archaebacteria and Eubacteria.
• This was now called the 6 kingdom classification and was proposed by Carl Woese et al.
• Carl Woese's six kingdoms include Animalia, Plantae, Fungi, Protista, Archaea/Archaeabacteria, and Bacteria/Eubacteria.

So, the correct answer is option A.
