Science Olympiad: Microbes

Microorganisms

Microscopic organisms essential for life that play critical roles in ecosystems, human health, and biogeochemical processes.

Prokaryotic Cells

Simple, unicellular organisms without a defined nucleus or organelles, including bacteria and archaea.

Eukaryotic Cells

More complex cells that possess a nucleus and organelles, such as mitochondria and chloroplasts.

Viruses

Acellular entities composed of nucleic acids encapsulated in a protein coat that require a host cell for replication.

Prions

Infectious proteins that cause neurodegenerative diseases by inducing abnormal folding of normal proteins in the brain.

Bacteria

Unicellular, prokaryotic microorganisms with diverse shapes and metabolic strategies including autotrophy and heterotrophy.

Harmful Algal Blooms

Blooming algal species that produce toxins, leading to ecological imbalances affecting aquatic life and humans.

Pathogenic Microbes

Microbes such as some bacteria, viruses, and protozoa that can cause diseases in humans, animals, and plants.

Antibiotics

Medications effective against many bacterial infections, requiring judicious use to combat antibiotic resistance.

Metabolism

The set of life-sustaining chemical reactions that involve energy acquisition to maintain and reproduce cells.
