Biology Classification and Kingdoms Quiz

A system for grouping organisms based on shared characteristics. Examples include the two-kingdom, three-kingdom, and five-kingdom systems.

The oldest classification system, dividing organisms into two groups: Plantae (plants) and Animalia (animals).

Expanded upon the two-kingdom system by adding the kingdom Protista, which included single-celled organisms with both plant-like and animal-like characteristics.

A system of biological classification that divides all living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

A group of organisms that share a common ancestor and are more closely related than organisms in other domains.

A domain containing single-celled organisms that often live in extreme environments, such as hot springs and deep-sea vents.

A domain containing single-celled organisms that are abundant in all environments, including our bodies.

A domain containing all organisms with a nucleus, including plants, animals, fungi, and protists.

Organisms that get their food by breaking down dead organic matter.

The most specific category in the classification system, grouping organisms that can interbreed.

The level in the classification system that groups together related families.

The level that groups together related orders, sharing characteristics.

The level in the classification system that groups together related classes.

A broad category of eukaryotic organisms that includes various unicellular and colonial organisms. These organisms can be animal-like, plant-like, or fungi-like.

A kingdom of eukaryotic organisms characterised by their ability to produce their own food through photosynthesis. They play a crucial role in maintaining ecosystems.

A kingdom of eukaryotic organisms that obtain nutrients by absorbing organic matter from their surroundings. They are essential for decomposition and nutrient cycling.

A kingdom of eukaryotic organisms characterized by their ability to move independently and obtain food by consuming other organisms.

A group of organisms that can interbreed and produce fertile offspring.

The system of giving each organism a unique two-part name: genus and species.

The first part of a scientific name, grouping similar species together.

The second part of a scientific name, specifying the particular species within a genus.

A universal scientific language used for naming organisms to avoid confusion.

Organisms that have features of both living and non-living things.

Viruses lack a cellular structure and organelles.

Viruses reproduce using the machinery of their host cell.

The cross between a male donkey and a female horse, resulting in an infertile offspring.

An organism that is incapable of reproducing, often due to an odd number of chromosomes.

The grouping of organisms based on shared characteristics.

A hierarchical system that classifies organisms based on their evolutionary relationships, including naming and identification.

The study of the diversity and evolutionary relationships of organisms.

Acellular infectious agents composed only of proteins, causing diseases in plants.

A classification system that groups organisms into three domains: Archaea, Bacteria, and Eukarya.

A domain containing all organisms with a nucleus, including plants, animals, fungi, and protists.
