Briefly describe about Protista kingdom and explain?

Give brief explanation about the Monera kingdom?

 

Characteristics of Kingdom Monera:

• Organisms are unicellular, made of a single cell.
• They have a prokaryotic cell structure.
• The cell lacks a distinct nucleus. Nuclear material is organised in the form of a circular, double-stranded and helical DNA, devoid of a nuclear membrane.
• The cytoplasm lacks well-organised cell organelles, except for ribosomes.
• The cell wall is typicallypresent, except in Mycoplasmas.
• The mode of nutrition is either autotrophic or heterotrophic.
• Examples: Bacteria, Cyanobacteria, Mycoplasma 

 

Characteristics of Kingdom Protista:

• Organisms contain a well-defined nucleus enclosed in a nuclear membrane and the presence of a nucleolus.
• The protoplasm is surrounded by a plasma membrane.
• The cytoplasm contains various cell organelles.
• Nuclear material is organised in the formof a linear, double-stranded and helical DNA along with proteins.
• Examples: Chlamydomonas,Euglena,Amoeba,Paramoecium,Pandorina
