Click on the flashcard to see the answer



What is the biological classification system called?

It is called taxonomy, which organizes living organisms into hierarchical categories.

Who developed the modern classification system?

Carolus Linnaeus developed the modern classification system.

What are the main levels of classification in taxonomy?

The main levels are Kingdom, Phylum, Class, Order, Family, Genus, and Species.

How many kingdoms are there in modern biological classification?

There are six kingdoms: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria.

What characteristics define the Animalia kingdom?

The Animalia kingdom includes multicellular organisms that are usually mobile and obtain food by consumption.

What are two examples of organisms in the Plantae kingdom?

Examples include oak trees and roses.

What is a species in biological classification?

A species is the most specific level of classification, identifying organisms that can breed and produce fertile offspring.

Why is taxonomy important in biology?

Taxonomy is essential for understanding relationships between organisms and for identifying and naming species.

What kingdom includes single-celled eukaryotic organisms?

The Protista kingdom includes single-celled eukaryotic organisms.

What distinguishes the Fungi kingdom from the Plantae kingdom?

Fungi obtain nutrients through absorption, while Plantae primarily use photosynthesis.

How are living organisms grouped in taxonomy?

Living organisms are grouped based on shared characteristics, genetics, and evolutionary relationships.

What is binomial nomenclature?

It is a two-part naming system for species using genus and species names.

How can DNA analysis influence classification?

DNA analysis can reveal genetic relationships, leading to changes and updates in classification.

What is the role of phylogenetic trees in taxonomy?

Phylogenetic trees illustrate the evolutionary relationships between different species or groups.

Why might classification systems change over time?

As scientific knowledge and technology advance, new evidence can lead to changes in our understanding of relationships between organisms.
