MONERA

Basic Characteristics:

• Unicellular organisms. • Nucleus and cell organelles are absent. • May or may not have cell wall. • Mode of Nutrition: Autotrophic or heterotrophic. • Able of nitrogen fixation.• Examples: Bacteria, blue-green algae or cyanobacteria and mycoplasma

EXAMPLES

Bacteria CyanobacteriaMycoplasma

PROTISTA

Basic Characteristics:

• Unicellular organisms.• A well defined nucleus and cell organelles are present. • Mode of Nutrition: autotrophic or heterotrophic. • Some of these organisms have appendages like cilia and flagella for movement. • Diatoms, protozoans and algae are few examples

EXAMPLES

Protozoan DiatomsAlgae

QUESTIONS

• Name the biologists who classified all living organisms into Kingdoms? Also name the kingdoms?

• On what basis are organisms classified?

• What is the ‘basic unit of classification’?

• Differentiate between Monera and Protista on basis of their characteristics?
