Answers
Explanation:
Characteristics of Monera
The Monerans are unicellular organisms.
They contain 70S ribosomes.
The DNA is naked and is not bound by a nuclear membrane.
It lacks organelles like mitochondria, lysosomes, plastids, Golgi bodies, endoplasmic reticulum, centrosome, etc.
They reproduce asexually by binary fission or budding.
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
