Question

Qu.1. Use Whittaker's method to classify bacteria, protozoa, fungi,Algae,prokaryotes and eukaryotic microbes.​

Answer 1

Answer:

R.H.Whittaker's classification

• it was developed in the year 1969 by R.H.Whittaker

• it is called FIVE KINGDOM CLASSIFICATION

• the five kingdoms are MONERA , PROTISTA, FUNGI, PLANTAE ,ANIMALIA

• the new kingdom introduced in this classification is kingdom PROTISTA.

• he grouped all the UNICELLULAR EUKARYOTES in kingdom protista

BASIS OF CLASSIFICATION:

• mode of nutrition...... autotrophic or heterotrophic

• cell type....... unicellular or multicellular

• nucler organization...... prokaryotic or eukaryotic

• cell structure.....presence or absence of cell wall

• phylogenetic relationships

KINGDOM MONERA:

• it includes BACTERIA, cyano bacteria, mycoplasma, PROKARYOTES.
• prokaryotes are those organisms that do not have well defined nucleus and do not have membrane bound organelles

KINGDOM PROTISTA:

• this kingdom has all unicellular eukaryotes.
• eukaryotes are those that have well defined nucleus and membrane bound organelles
• it includes PROTOZOA and EUKARYOTIC MICROBES

KINGDOM FUNGI:

• it includes FUNGI.
• fungi have chitinous cell wall and they are heterotrophic

KINGDOM PLANTAE:

• it includes ALGAE, plants
• they have chlorophyll pigments
• they are mostly autotrophic and have cellulosic cell wall

KINGDOM ANIMALIA:

• it includes animals that are terrestrial or aquatic.
• these organisms do not have cell wall
• they are completely heterotrophic
