Non-cellular organism made of genetic material and protein that invades living cells.

Viruses consist of a nucleic acid core and a protein coat (capsid), often with an envelope.

The study of viruses, focusing on their structure, function, and effects on living organisms.

Viruses are considered living when inside host cells and non-living outside of them.

Viruses that cause diseases in humans, plants, and animals (e.g., HIV, influenza).

The protein coat that encases a virus's genetic material.

Use of viruses to deliver genes to target cells for medical treatment.

Varies widely but can include fever, fatigue, and body aches depending on the virus.

Heterotrophic organisms that digest food externally using exoenzymes.

Enzymes produced by fungi to digest food externally before ingestion.

A complex carbohydrate used in the biosynthesis found in fungal cell walls.

The sexual reproductive stage of fungi.

The asexual reproductive stage of fungi.

Classification of all eukaryotic, multicellular, photosynthetic plants.

Process by which plants convert sunlight into energy.

The structural component of plant cell walls.

Group of animals with mammary glands, hair, and four-chambered hearts.

Animals that give birth to live young, developing inside the mother.

Animals that lay eggs with direct development; fertilization is internal.

Diverse group of animals with a backbone, including mammals, birds, and fish.

A phylum comprising segmented worms, including earthworms and leeches.

The largest phylum, including over 1 million species of insects such as locusts and scorpions.

The second largest phylum of animals, found in aquatic and terrestrial environments; includes squids and snails.

Consists of sea stars and sea urchins, with around 6,000 species.

Animals in this phylum have a notochord, dorsal nerve cord, and gill slits; includes vertebrates.

Invertebrates are cold-blooded and lack a skeleton made of bone; their temperature depends on the environment.

Invertebrates represent 90% of Earth's estimated 15-30 million species, showcasing vast diversity.

Adults are radially symmetrical; larvae are bilaterally symmetrical.

Animals with a body cavity completely lined with mesoderm.

A unique system that aids in locomotion and respiration.

Fertilization occurs outside the female's body, typical in many aquatic species.

Development that involves free-swimming larval stages before adulthood.

A flexible rod structure that is present during embryonic development in chordates.

A phylum characterized by round worms with organ-system level organization, bilateral symmetry, and pseudocoelomate body structure.

Refers to species where male and female reproductive organs are on separate individuals, common in round worms and segmented worms.

The first occurrence in any phylum where digestive tract has two openings, allowing for a more efficient digestion process.

Refers to the body structure of annelids being divided into repeated segments, aiding in locomotion and differentiation.

A system where blood circulates within vessels, present in annelids, allowing for efficient nutrient and oxygen transport.

Excretory organs found in annelids responsible for waste removal and osmoregulation.
