Question # 3

What are basis of classification of life into domains?

Ans 3:

Question # 5

Define Biodersity, Classification, Taxonomy , Systemsatic, Domain, Taxa, Species

Ans 1: Biodiversity:
Biodersity is defined as The variety of living organisms on Earh.
Ans 2: Classification :

Ans 3: Taxonomy:
Taxonomy is the brach of biology concerned with identficiation, naming and classification of organisms.
Systematics:

Ans 4: Domain :
In 1990 Carl Woese introduced a three domains system of classification. The three domains of life are Archaea, Bacterial and Eukarya.
Taxa:
The group into which organisms are classified are known as taxonomic categories or taxa .The taxa form a ladder,called taxonomic heirarchey. Therere are seven main taxonomic ranks. Kingdo, Phylum or division, class order family, genus and species.
Ans 5: Species: Species is a group of similar organismsm capable of interbreeding or exchanging genes among themselves and producing fertile offspring.

Ans 1: The term used for the variety of life on Earth is biodiversity, or biologicla diversity.
Ans 2: Definition :
Biodiversity means the variety of organismsm in a particular area including all living things and their interactions. It encompasses the variety of genes, species, ecosystems and functions.

Question # 7

Difference betwen Bacteria and Protists

Ans 1: Bacteria:
i. Prokaryotic organismsm
ii. They are unicellular, filamentous or colonial and are relatively simple in structure
Example: Bacterial and Cyanobacteria
Ans 2: Protists:
i. Eukaryotic organisms
ii. Univellular or simple multicellular and mostly equatic
Example: Amoeba, Euglena, and slime molds.

Question # 8

Compare two kingdow, Kingdom, and five kingdom classifciation system.

Ans 1: Two Kingdom :
i. It includes two kingdomw Plantae and nimalia
ii. Bacteria and cyanobacteria were placed in plant kingdom
iii. Uniellular or simple multicellular eukaryotes wrongly placed in kingdom plantae and animalia.
iv. Fungi are wrongly placed in kingdom plantae
Ans 2: Three Kingdom:
i. It includes three kingdoms plantae, Animalia, Protista
ii. Euglena was placed in kingdom protista.
iii. Multicellular microscopic organismsm were spearated from uncellular microscopic organisms.
iv. Fungi were placed in kingdom plantae
Ans 3: Five Kingdom:
i. It includes five kingdoms Monera, protista, Fungi, plantae and Aimals
ii. Bacteria and cyanobacteria are placed in kingdom Moneara
iii. Unicellular or simple multicellular eukaryotes placed in kingdom Protista
vi. Fungi are placed in kingdom Fungi
