Fungi that cause plant diseases, leading to tissue decay and death.

A disease of cereal crops caused by the fungus Claviceps purpurea, producing harmful toxins.

Animal disease caused by ergot, marked by convulsions, hallucinations, and gangrene.

Toxic and carcinogenic compounds produced by Aspergillus fungi, contaminating food.

Fungi causing plant diseases.

Damaging or destroying the quality or usefulness of crops.

A chemical in ergot (lysergic acid) used to produce the drug lysergic acid diethylamide (LSD).

Reduced crop yields and potential harm to humans and animals through toxins.

Eukaryotic organisms that don't belong to the kingdoms Animalia, Fungi, or Plantae.

Protists that are microscopic and live in environments like pond water.

Some protists, such as kelp, are large and multicellular.

Protists are diverse in morphology, physiology, and ecology.

Many protists are found in aquatic, damp, and terrestrial environments.

Some protists live in symbiotic relationships with other organisms.

Some protist species are parasites that infect other organisms.

Protists have complex cells, often microscopic and unicellular, but some are multicellular.

Protists that cause disease and need to infect other organisms to survive.

Genus of protists causing malaria.

Disease caused by Plasmodium.

Plasmodium species causing most malaria cases.

Malaria is transmitted by mosquitoes (Anopheles gambiae).

P. falciparum infects red blood cells and destroys them.

Protist species that cause infection and illness in humans.

A protist responsible for African sleeping sickness, known for its ability to evade the immune system by changing its surface glycoproteins.

A deadly disease caused by the trypanosome Trypanosoma brucei. It affects the nervous system, leading to sleep disturbances and ultimately death if untreated.

A strategy used by Trypanosoma brucei to evade the immune system. The parasite repeatedly changes its surface glycoproteins, rendering antibodies ineffective.

A disease caused by Trypanosoma cruzi, transmitted by a blood-sucking bug, affecting the heart and digestive system.

A species of Trypanosoma responsible for Chagas disease, mainly found in Latin America.

A species of Plasmodium responsible for a particularly dangerous form of malaria, leading to severe symptoms and potentially death.

Insects, like kissing bugs, that transmit Trypanosoma cruzi, the causative agent of Chagas disease.

An organism that obtains nutrients from decaying organic matter, primarily dead plants.

Enzymes secreted by fungi that break down complex molecules like cellulose and lignin into smaller, absorbable units like glucose.

Fungi play a crucial role in recycling nutrients locked in dead organisms, making them available for other living things.

Using fungi to break down pollutants and contaminants in the environment.

The classification of fungi into major groups based on their reproductive methods.

A division of fungi characterized by flagellated spores, often found in aquatic environments.

Fungal division known for producing zygospores, resistant structures for harsh conditions.

A large division of fungi that produce spores within sac-like structures called asci.

A plant disease caused by the oomycete Plasmopara viticola that affects grape vines, leading to stunted growth, discolored leaves, and overall plant decline.

A devastating plant disease caused by the oomycete Phytophthora infestans that infects potato plants, causing rot and decay of stalks and stems, often leading to complete crop failure.

A major historical event in the 19th century caused by the potato late blight, leading to widespread starvation and death in Ireland, forcing many to emigrate.

Protists play a crucial role in breaking down dead organic matter, contributing to nutrient cycling and maintaining ecosystem health.

A diverse group of mostly microscopic organisms, including protists, that drift in water and form the base of aquatic food webs.

Protists that produce their own food through photosynthesis, serving as primary producers in ecosystems.

Photosynthetic dinoflagellates that live symbiotically with coral polyps, providing them with energy through photosynthesis.

The loss of algal pigments in corals, often caused by environmental stress, leading to a white appearance and eventual death.
