• A. Some unicellular algae (Chlamydomonas) were kept in Kingdom Protista, away from remaining algae placed in Kingdom Plantae.
• B. Chlorella and Chlamydomonas (autotrophic) were placed with Paramoecium and Amoeba (heterotrophic) in Kingdom Protista.
• C. Fungi were placed in a separate kingdom as their mode of nutrition differs from all other plants.
• D. There was no place for viruses and lichens

Answer 1

The correct option is C Fungi were placed in a separate kingdom as their mode of nutrition differs from all other plants.

Robert H. Whittaker proposed the Five Kingdom Classification in 1969. The five kingdoms were Monera, Protista, Fungi, Plantae and Animalia.

Merits:

• Prokaryotes got a separate place as Kingdom Monera.
• Unicellular and multicellular organisms were kept separate.
• Fungi were placed in a separate kingdom as their mode of nutrition differs from all other plants.
• Autotrophs and heterotrophs were placed separately.
• Showed phylogenetic relationship.

Demerits:

• Some unicellular algae (Chlamydomonas) were kept in Kingdom Protista, away from remaining algae placed in Kingdom Plantae.
• Chlorella and Chlamydomonas (autotrophic) were placed with Paramoecium and Amoeba (heterotrophic) in Kingdom Protista.
• There was no place for viruses and lichens.
