using whittaker method classify Bacteria Protozoa Fungi algae prokaryotic and Eukaryotic microbes
Answers
Answer:
According to Robert Harding Whittaker, given below are the characteristic features of bacteria, protozoa, fungi, algae, prokaryotic and eukaryotic microbes:
1. Kingdom Monera
As all the organisms are unicellular, there is an absence of multicellular body designs.
They may have either an autotrophic or heterotrophic mode of nutrition.
These are prokaryotic cells without a well-defined nucleus or cell organelles.
All types of blue-green algae and bacteria are included in this kingdom.
2. Kingdom Protista
These are unicellular, eukaryotic organisms with a well-defined nucleus enclosed in a nuclear membrane.
These organisms can be either autotrophic or heterotrophic.
They have whip-like flagella or pseudopodia or hair-like cilia which helps in locomotion.
3. Kingdom Fungi
They may be unicellular or multicellular, non-green, heterotrophic, and eukaryotic organisms.
Most of them are saprotrophs and they feed on dead organic matter.
Some fungi are thread-like and most of the nuclei are present in the cytoplasm.
Their cell walls are made up of complex and tough sugar called ‘Chitin’.
Examples- Mushrooms, Baker’s yeast, Penicillium, Aspergillus (Fungus on corn).
4. Kingdom Plantae
They are mainly multicellular and eukaryotic organisms.
They are of non-motile nature.
The plant cells mostly contain chlorophyll pigments and they are an autotrophic mode of nutrition.
Their cell wall is composed of cellulose and not ‘Chitin’ like that of fungi.
5. Kingdom Animalia
These organisms are multicellular eukaryotes.
Absence of cell walls in these organisms.
Absence of chloroplast in animal cells. They mostly have a heterotrophic mode of nutrition.
