Biology Taxonomy Quiz

A system for classifying organisms into groups based on shared characteristics.

The two-part scientific name given to a species, consisting of the genus and species names.

A hierarchical system for classifying organisms into increasingly specific groups, from Kingdom to Species.

The broadest category of classification in the Binomial Nomenclature system, encompassing a wide range of organisms.

The classification system of living organisms, encompassing six major groups.

Organisms made of a single cell.

Organisms composed of many cells that work together.

Cells that lack a membrane-bound nucleus.

Cells that have a membrane-bound nucleus.

A small loop of DNA found in prokaryotic cells.

A type of viral infection where the virus replicates rapidly within the host cell, eventually causing the cell to burst and release new virus particles.

The process where a virus attaches to the surface of a host cell.

The process where a virus injects its genetic material into a host cell.

The process by which a virus uses the host cell's machinery to replicate its own genetic material.

The process where newly assembled virus particles are released from the host cell, often by causing the cell to burst.

Viruses are not considered living organisms because they lack key characteristics of life, such as independent reproduction and metabolism.

Viruses can't reproduce on their own; they need a host cell's machinery to replicate.

Antibiotics target bacteria, which are living organisms with different structures and processes than viruses.

The capsid is a protein shell that surrounds and protects a virus's genetic material.

Viruses are classified based on size, shape, and the type of genetic material they contain (DNA or RNA).

Protists that can cause diseases in plants and animals.

A single-celled organism that causes sleeping sickness, transmitted through mosquito bites.

A protist that causes malaria, spread through mosquito bites.

The branching filaments that form the body of a fungus.

The network of hyphae that makes up the main body of a fungus.

Fungi that benefit both themselves and other organisms, like plants, by exchanging nutrients and resources.

Fungi that obtain their nutrients by breaking down dead organic matter, playing a crucial role in nutrient recycling in ecosystems.

Fungi that actively hunt and capture prey, often using specialized structures like traps to catch small organisms.

A group of fungi that are adapted to living in water, often playing important roles in aquatic ecosystems.

A major group of fungi characterized by their club-shaped reproductive structures (basidia).

The viral DNA becomes dormant; it is integrated into the host's DNA and is replicated along with it. This process allows the virus to remain undetected, enabling it to persist in the host for extended periods.

A virus's ability to evolve is one of the defining features that it shares with living things. This process is crucial for the virus to adapt to new hosts and environments.

Cold sores are an example of a virus that remains dormant in the body for extended periods. When triggered, the virus reactivates, causing the characteristic lesions.

Bacteriophages inject their DNA into a host cell, which then uses this information to produce more viruses. Animal viruses, however, need to enter the host cell through endocytosis or membrane fusion to release their genetic material.

The lysogenic cycle consists of five stages: attachment, injection/entry, integration into host cell's DNA, dormancy/normal cell functions, and the triggering of viral DNA to be released, leading to the lytic cycle.

All animals with a spinal cord and internal skeleton.

Animals with a spinal cord: 17 phyla. Animals without a spinal cord: 16 phyla.

They have sense organs, allowing them to move efficiently in their environment. This helps animals evolve.

Simple animals with specialized tissues, like tentacles and stingers. Examples include jellyfish and corals.

Sponges, with simple bodies and flagellated cells lining the central cavity.

A form of asexual reproduction where an offspring grows from a part of the parent. Think of a plant growing new branches or a yeast cell budding off.

A type of sexual reproduction where genetic material is transferred directly between two bacteria using a pilus. Think of two cells connecting and exchanging DNA through a tube.

A form of asexual reproduction where a single cell divides into two identical daughter cells. Think of a single cell splitting in half.

This is a type of cell division where a cell duplicates its chromosomes and then divides into two identical daughter cells. Each new cell receives a full set of chromosomes containing the same genetic information.

The process by which a cell divides to produce two identical daughter cells, each containing a complete set of chromosomes. This is a type of cell division that occurs in all living organisms.
