In Whittaker’s five-kingdom system of classification, eukaryotes are placed in Three kingdoms Four kingdom Five kingdom One kingdom

In Whittaker’s five-kingdom system of classification, eukaryotes are placed in four kingdoms. These include:

1. Monera – This kingdom includes prokaryotic organisms (bacteria).
2. Protista – This kingdom consists of mostly unicellular eukaryotic organisms like protozoa and some algae.
3. Fungi – Eukaryotic organisms that are primarily multicellular (with the exception of yeasts) and obtain nutrients through absorption.
4. Plantae – This kingdom comprises multicellular eukaryotic organisms that perform photosynthesis.
5. Animalia – This kingdom includes multicellular eukaryotic organisms that are typically heterotrophic.

Thus, eukaryotes are part of four kingdoms (Protista, Fungi, Plantae, and Animalia) in this classification system.
