Understanding Biological Classification

What is the primary purpose of classification in biology?

• To create confusion with different names

• To arrange organisms into orderly groups based on similarities

• To reduce the number of species on Earth

• To make Latin the universal language

Who is known as the "Father of Taxonomy"?

• Charles Darwin

• Carolus Linnaeus

• Gregor Mendel

• Louis Pasteur

• Both genus and species

• Eubacteria

Explain the importance of using Latin or Greek in naming organisms.

• They are modern languages spoken worldwide.

• They are dead languages, so meanings do not change over time.

Describe the hierarchical structure of biological classification from the broadest to the most specific.

• Species, Genus, Family, Order, Class, Phylum, Kingdom

• Phylum, Kingdom, Class, Order, Family, Genus, Species

What are the main characteristics of organisms classified under the domain Eukarya?

• They have no nucleus.

• They have a nucleus and membrane-bound organelles.

• They are all unicellular.

• They are all prokaryotic.

• Plantae

• Fungi

• Protista
