♦ Five Kingdom of Classification introduced by - R.H Whittaker in 1969.

➧ Five Kingdoms 0f Classification are:-
▬▬▬▬▬▬▬▬▬▬▬▬⤵

❶❭ Kingdom Monera:-━━━━━━━━━━━━━━━━━━☟

❱ They are the simplest unicellular & prokaryotic organisms.

❱ They are typically unicellular organisms but one group is mycelial.

❱ The genetic material in these organisms is the naked circular DNA.

❱ Bacterial flagellar if present a simple and composed of a single fibre of protein.

❱ They may be Photo-autotrophs or Chemo-autotrophs.

◉Ex:- Cyanobacteria & Mycoplasm

❷❭ Kingdom Protista:-━━━━━━━━━━━━━━━━━━☟

❱ They are the first simple unicellular eukaryotes organisms.

❱ They have a well-defined nucleus & also membrane bound cell organelles.

❱ Locomotion occurs with the help of Cilia, Flagella & Pseudopodia.

❱ They are mostly unicellular but some like algae are multicellular.

❱ Most of live in water & some in moist soil or even the body of human & plants.

◉Ex:- Amoeba & Euglena

❸❭ Kingdom Fungi:-━━━━━━━━━━━━━━━━━━☟

❱ They are simple, Eukaryotes, Non-green, Heterotrophic & multicellular organisms.

❱ Cell wall is made up of chitin.

❱ They store food at Glycogen.

❱ They are mostly multicellular expcept Yeast.

❱ They reproduce by spore formation.

❱ They live in symbiotic relationship with blue-green algae.

◉Ex:- Yeast & Penicillin

❹❭ Kingdom Plantae:-━━━━━━━━━━━━━━━━━━☟

❱ They includes multicellular & green eukaryotes.

❱ Their cell wall are made up of cellulose.

❱ They Stored food in the form of Starch & 0il.

❱ Plant grow throughout their life.

❱ They are autotrophs.

❱ They have an ability to grow by cell division.

❱ They contain photosynthetic pigments which are present in plastids.

◉Ex:- All green photosynthetic plants

❺❭ Kingdom Animalia:-━━━━━━━━━━━━━━━━━━☟

❱ They includes multicellular & non green eukaryotes.

❱ Cell wall is absent.

❱ They Stored food in the form of Glycogen & fat.

❱ They have limited growth which stop after maturity.

❱ They are Heterotrophic.

❱ Ingestive nutrition & digestion.

❱ Higher level of tissue organization.

❱ 0rgans are internal.

◉Ex:- All Animals
