1. DIVERSITY IN
LIVING
ORGANISMS
BY- KHUSH AHUJA

2. IN THIS CHAPTER WE
WILL KNOW
• INTRODUCTION
• BASIS OF CLASSIFICATION
• CLASSIFICATION AND EVOLUTION
• HIERARCHY OF CLASSIFICATION
• KINGDOMS OF ORGANISMS
• KINGDOM PLANTAE
• KINGDOM ANIMALIA
• VERTEBRATES
• COMMON NAME

3. 5 KINGDOMS OF
CLASSIFICATION
• BASIS OF CLASSIFICATION
• FEATURES OF EACH KINGDOM
• KINGDOM PLANTAE
• KINGDOM ANIMALIA

4. WHAT IS MEANT BY
DIVERSITY
• It is the various types of living beings which differ from
one another in appearance , internal structure , nutrition ,
behievour , habit ,etc.
OR WE CAN SAY
• Variability among living organisms or a variety of life
forms found in a region.

5. BASIS OF
CLASSIFICATION
• CLASSIFICATION:- On the basis of similarities and
differences organisms are arranged in different groups.
• NEED OF CLASSIFICATION:-
1. Classification makes our study easy and convenient.
2. Gives an idea of diversity of living organisms in a world.

6. MAIN TERMS TO
REMEMBER
• TAXONOMY:- It is the identification , nomenclature and
classification of organisms.
• TAXON:- Various grouping level or ranks in classification
is taxon.
• NOMENCLATURE :- It is a process of giving scientific
name to different organisms of living world.

7. CATEGORIES OF
DIVISION
• KINGDOM
• PHYLUM(ANIMALS) / DIVISION (PLANTS)
• CLASS
• ORDER
• FAMILY
• GENUS
• SPECIES ( LOWEST LEVEL OF DIVISION)

8. EASY METHOD TO
LEARN
• We can learn this by a simple method by :-
• KEEP PLATE CLEAN OR FAMILY GETS SICK.
• By the chart we can understand :-
• As we go downwards similarities will increase
but the no of organisms decrease.
• As we go upwards the no of organisms increase and
similarities decrease.

9. NOMENCLATURE
• NOMENCLATURE :- It is a process of giving scientific
name to different organisms of living world.
• Father of nomenclature is CARLOUS LINNAEUS.
• Example :- magnifera indica mango
• Panthera tigris  tiger
• Panthera leo lion

10. RULES OF
NOMENCLATURE
• First name should be the generic name and the second
word should be species name. eg- Homo sapien
humans. Homo is the generic name, sapien is species
name.
• First letter of generic name should be in capital case and
rest in small case.
• If handwritten it should be underlined.
• If typed must be in italics.

11. DIVISION OF KINGDOM
DONE BY DIFFERENT
SCIENTIST
• ERNST HAECKEL :- Into PLANT KINGDOM,ANIMAL
KINGDOM,PROTISTA.
• COPELAND :- Added MONERA in above.
MONERA,ANIMAL,PLANT , PROTISTA.
• ROBERT WITTAKER :- He introduced 5 kingdom.
PLANT,ANIMAL,PROTISTA,MONERA,FUNGI.
