Five Kingdom Classification

Five Kingdom Classification

• Whittaker classified the organisms into five kingdoms are these are as follows:-

1. Kingdom Monera
2. Kingdom Protista
3. Kingdom Fungi
4. Kingdom Plantae
5. Kingdom Animalia

1) Kingdom Monera:-

• These organisms do not have defined nucleus or organelles some of them have cell walls while some do not.

• These group includes bacteria, blue green algae or cyanobacteria and mycoplasma.

2) Kingdom Protista:-

• This group includes many kinds of unicellular eukaryotic organisms some of these organisms use appendages, such as hair like cilia or whip like flagella for moving around. 

• Their mode of nutrition can be autotrophic or heterotrophic.

• Examples are unicellular algae, diatoms and protozoans.

3) Kingdom Fungi:-

• These are heterotrophic eukaryotic organisms.

• They use decaying organic material as food and are therefore called saprophytes.

• They have cell-walls made of a tough complex sugar called chitin.

4) Kingdom Plantae:-

• These are multicelluar eukaryotes with cell walls.

• They are autotrophs and use chlorophyll for photosynthesis. Thus all plants are included in this group.

5) Kingdom Animalia:-

• These include all organisms which are multicellular eukaryotes without cell walls. 

• They are heterotrophs.
