Question

What type of organisms were included by Whittaker in kingdom fungi?

Answer 1

Carolus Linnaeus was the first to propose a two-kingdom categorization, with just the kingdom Plantae and kingdom Animalia included. There was no distinction between eukaryotes and prokaryotes, unicellular and multicellular organisms, photosynthetic and non-photosynthetic organisms, or photosynthetic and non-photosynthetic organisms. There were many organisms that could not be classed as either plants or animals, so putting them all in one of the two kingdoms was insufficient.
The five-kingdom classification was thus proposed by R.H. Whittaker in $1969$. Certain characteristics, such as mode of nourishment, thallus organization, cell structure, evolutionary relationships, and reproduction, were used to classify the organisms. Monera, Protista, Fungi, Plantae, and Animalia are the five kingdoms classified in this way.

Complete answer:
Fungi are eukaryotic organisms that include yeasts, moulds, and mushrooms as well as other microorganisms. These organisms belong to the fungus kingdom. The organisms in the Kingdom Fungi have a cell wall and are widely distributed. Among living organisms, they are categorized as heterotrophs.
Fungi have the following important characteristics:
1. Fungi are eukaryotic organisms that are non-vascular, non-motile, and heterotrophic.
2. They might be filamentous or unicellular.
3. Spores are used to replicate.
4. Alternation of generation is a phenomenon that occurs in fungi.
5. Because fungi lack chlorophyll, they are unable to perform photosynthesis.
6. Food is stored in the form of starch by fungi.

Note:
Fungi aren't the same as plants. Kingdoms are huge, basic groups of living organisms that may be studied. For many years, fungi were included in the Plant Kingdom. Then scientists discovered that while fungus is related to animals, they are distinct life forms.
The Chytridiomycota (chytrids), Zygomycota (bread moulds), Ascomycota (yeasts and sac fungi), and Basidiomycota (basidiomycetes) are the four groups of fungi (club fungi).
