Plants are multicellular organisms, while microorganisms are typically unicellular or acellular.

Bacteria and archaea belong to the domain Bacteria, while eukaryotes (including protists, fungi, plants, and animals) belong to the domain Eukarya.

The common cold is caused by a virus, specifically a rhinovirus.

Athlete's foot and ringworm are caused by fungi, specifically dermatophytes.

Malaria is caused by a protist, specifically a protozoan called Plasmodium.

Antibiotics are produced by certain bacteria, such as penicillin-producing Penicillium fungi.

Bacteria play a crucial role in the decomposition of organic matter, breaking it down into simpler compounds.

Cheese and yogurt are produced through the fermentation of milk by bacteria, such as lactic acid bacteria.

Bacteria play a crucial role in the nitrogen cycle, converting nitrogen gas into forms that can be used by plants.

Certain bacteria, such as Escherichia coli, are used in the production of biofuels, converting biomass into fuel.

Protists, specifically algae, are responsible for a significant portion of oxygen production through photosynthesis.

Beer and wine are produced through the fermentation of grains and fruits by fungi, such as yeast.

Certain bacteria, such as cellulolytic bacteria, are responsible for breaking down cellulose in the digestive system of herbivores.

Traditional fermented foods are produced through the fermentation of vegetables by lactic acid bacteria.

Certain bacteria, such as Streptomyces, are known for producing antibiotics that are used to treat bacterial infections.
