Which of the following was not a kingdom in Linnaeus’s taxonomy?

In Linnaeus’s original taxonomy, the following kingdoms were recognized:

1. **Animalia** (animals)

2. **Plantae** (plants)

Linnaeus did not include the following kingdoms, as they were introduced later:

– Protista: Added by Ernst Haeckel in 1866.

– Fungi: Recognized as a separate kingdom in the 20th century.

– Monera : Introduced later to include bacteria and similar organisms.

So, any of these options (Protista, Fungi, Monera) were not part of Linnaeus’s original classification system.

Protist. Linnaeus’ original system of classification classified everything in nature into a hierarchy. He proposed that there were three large groups, called kingdoms, into which the whole of nature could fit. These kingdoms were plants, animals and minerals.
