DEFINE ENVIRONMENT OF EARTH

4.
WHERE IS THE
BASIC UNIT OF
LIFE?

5.
MORE CHARACTERISTIC
•LIVING THINGS ARE MADE OF CELLS.
•LIVING THINGS ADAPT TO THEIR ENVIRONMENT.

6.
BIODIVERSITY
• EARTH IS OCCUPIED BY DIVERSE KINDS OF LIVING ORGANISMS
• THEY LIVE IN VARIOUS ENVIRONMENTS.
• THE WORLD IS ESTIMATED TO HAVE 5 TO 30 MILLION SPECIES OF LIVING ORGANISMS.
• THUS THE EXISTENCE OF DIFFERENT FORMS OF A SPECIES OR GENUS AND DIVERSE
ADAPTATIONS FOR, VARIED SURROUNDINGS ARE REFERRED TO AS “BIODIVERSITY”.

TAXONOMIC SYSTEMS
•First introduced by
Aristotle (384-322 BC).
•He is considered as the
Father Of Biological
Classification.

9.
TAXONOMIC SYSTEMS
•Carl Linnaeus (1707 - 1778) the father of taxonomy.
•Binomial nomenclature for all species of animals and plants.
•Binomial nomenclature is a formal system of naming species of living things
• The highest rank was given the name "kingdom"
•Followed by four other main or principal ranks: the class, order, genus and species.
•Later two further main ranks were introduced, making the sequence kingdom, phylum or
division, class, order, family, genus and species.

10.
The five-kingdom system, proposed in 1969 by
Whittaker

11.
FACTORS OF CLASSIFICATION
•Structure of cells - {prokaryotic or eukaryotic }
•Structure of organism - {unicellular or multicellular}
•Mode of nutrition - photosynthesis in green plants,
absorption in fungi and ingestion in animals.
