Theory:

Protista:
It is a group that includes unicellular eukaryotic and a few simple multicellular eukaryotic organisms.
  • They may or may not have cell walls. Appendages such as hair-like cilia or whip-like flagella are the locomotory structures, pseudopodia are used by these organisms to move around.
  • They are both autotrophic and heterotrophic. These organisms are also known as primitive animals as they regarded as ancestors of all multicellular eukaryotic organisms.
  • Protists can be classified into two main groups. The plant-like protists are photosynthetic and are commonly called algae.
  • The algae are both unicellular and multicellular. The animal-like protists are known as protozoans and include the amoeba and paramecium.
  • They reproduce by fission or conjugation.
Example:
The unicellular algae, diatoms and protozoans such as amoeba, paramecium and euglena.

Fungi:
  • It is a group that includes multicellular non-green eukaryotic organisms. A few organisms among these use decaying organic material as food.
  • These type of organisms are known as saprotrophs or decomposers.
  • The organisms belonging to this kingdom secrete enzymes that digest the food and later absorb the digested food.
  • Some of them which depend on the living protoplasm for their food are known as parasites.
  • Most of the fungi have the capability of becoming multicellular organisms at particular stages of their lives.
  • The cell wall of fungi is made up of a tough complex sugar called chitin.
Example:
Yeasts, moulds, mushrooms or Agaricus and Rhizophus.
