Hey mate

Here is your ans

Molluca is the second largest animal phylum.They are terrestrial or aquatic having an organ system level of organisation .They are bilaterally symmetrical ,triploblastic animals.Thier mouth contains a file like rasping organ for feeding called Radula.

Classification of 5 kingdoms is proposed by ŘH Whittekar.

✔Kingdom Animalia.

✔kingdom Plantae

✔kingfom Monera(Bacteria)

✔Kingdom Fungi(Eukaryotes)

✔Kingdom Protista.

Molluscs=> They have more varied forms than any other animal phylum.

Ex:- Snails

♦ 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
