What is the biological classification system called?
Click to flip
It is called taxonomy, which organizes living organisms into hierarchical categories.
Click to flip
Who developed the modern classification system?
Click to flip
Carolus Linnaeus developed the modern classification system.
Click to flip
What are the main levels of classification in taxonomy?
Click to flip
The main levels are Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Click to flip
How many kingdoms are there in modern biological classification?
Click to flip
There are six kingdoms: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria.
Click to flip
What characteristics define the Animalia kingdom?
Click to flip
The Animalia kingdom includes multicellular organisms that are usually mobile and obtain food by consumption.
Click to flip
What are two examples of organisms in the Plantae kingdom?
Click to flip
Examples include oak trees and roses.
Click to flip
What is a species in biological classification?
Click to flip
A species is the most specific level of classification, identifying organisms that can breed and produce fertile offspring.
Click to flip
Why is taxonomy important in biology?
Click to flip
Taxonomy is essential for understanding relationships between organisms and for identifying and naming species.
Click to flip
What kingdom includes single-celled eukaryotic organisms?
Click to flip
The Protista kingdom includes single-celled eukaryotic organisms.
Click to flip
What distinguishes the Fungi kingdom from the Plantae kingdom?
Click to flip
Fungi obtain nutrients through absorption, while Plantae primarily use photosynthesis.
Click to flip
How are living organisms grouped in taxonomy?
Click to flip
Living organisms are grouped based on shared characteristics, genetics, and evolutionary relationships.
Click to flip
What is binomial nomenclature?
Click to flip
It is a two-part naming system for species using genus and species names.
Click to flip
How can DNA analysis influence classification?
Click to flip
DNA analysis can reveal genetic relationships, leading to changes and updates in classification.
Click to flip
What is the role of phylogenetic trees in taxonomy?
Click to flip
Phylogenetic trees illustrate the evolutionary relationships between different species or groups.
Click to flip
Why might classification systems change over time?
Click to flip
As scientific knowledge and technology advance, new evidence can lead to changes in our understanding of relationships between organisms.
