Scientific Classification and Cell Types

The video introduces taxonomy, explaining its importance in organizing living organisms. It covers the historical development of taxonomy from Aristotle to Linnaeus, focusing on the binomial nomenclature system. The classification hierarchy is detailed, including domains and kingdoms. The video also explains the use of dichotomous keys for identifying species.

Why are scientific names preferred over common names?

• They are more colorful.

• They are shorter.

• They are the same across all regions.

• They are easier to remember.

Who introduced the binomial nomenclature system?

• Carolus Linnaeus

• Aristotle

• Charles Darwin

What is a dichotomous key used for?

• To measure the size of organisms

• To identify species based on characteristics
