Animalia

 Cell Type: Eukaryotic
 Level of Organism: Tissue/Organ/Organ system
 Cell Wall: Absent
 Nutrition: Heterotrophic
 Motility: Mostly motile
 Organism: Sponges, Invertebrates,Vertebrates

Monera and Protista:

 The five kingdom classification was proposed by R.H. Whittaker in 1969.
 Five kingdoms were formed on the basis of characteristics such as cell

structure, mode of nutrition, source of nutrition and body organization.

 A revised six Kingdom classification for living world was proposed by
Thomas Cavalier-Smith in the year 1998.In that the Kingdom Monera is
divided in to Archaebacteria and Eubacteria.

Monera:
Kingdom Monera – Bacteria:
 All prokaryotes belong to the Kingdom Monera, which do not possess true
nucleus.
 Cells of prokaryotes do not have a nuclear membrane and any membrane
bound organelles.
 Most of the bacteria are heterotrophic, but some are autotrophs.
 Bacteria and Blue green algae are examples for monera.
Protista:
 The Kingdom Protista includes unicellularand a few simple multicellular
eukaryotes.
 There are two main groups of protists
 The plant like protists are photosynthetic and are commonly called algae.
 Algae include unicellular and multicellular types.
 Animals like protists are often called protozoans.
They include amoeba and paramecium
