1. Five Kingdom classification
System
-R.H. Whittaker

2. Complexity of cell structure- prokaryote, eukaryote
Complexity of organisms- unicellular, multicellular
Mode of nutrition- photo-autotrophy (in plantae),
absorptive heterotrophy or saprophytic (in fungi) and
ingestive heterotrophy (in animalia).
Ecological Lifestyle- Producers(plants), consumers
( animals), decomposers(fungi)
Phylogenetic relationships- prokaryote to
eukaryote, unicellular to multicellular
Many biologist accept classification of microorganism
proposed by R.H. Whittaker . He place all living things
except virus into 5 classes depend on following

4. Monera e.g. Bacteria Cyanobacteria
Protista - UnicellularEukaryotes e.g. microalgea
Fungi— Kingdom of MulticellularDecomposers (utilize nutrients by
absorption)
Plantae — Kingdom of Multicellular Producers (utilize nutrients by
photosynthesis)
Animalia — Kingdom of Multicellular Consumers (utilize nutrients by
ingestion)
