    Flashcards

    Antibiotic production

    Fungi are used to produce antibiotics, which are medicines that fight bacterial infections.

    Dutch elm disease

    Dutch elm disease is a fungal infection that attacks elm trees, often causing their death.

    Penicillin producing fungi

    Penicillin is a powerful antibiotic produced by a type of fungus called Ascomycetes.

    Mushrooms and puffballs

    Mushrooms and puffballs belong to the group of fungi called Basidiomycetes.

    Prokaryote shapes

    Prokaryotes cannot be cube shaped. They come in three main shapes: cocci (spherical), bacilli (rod-shaped), and spirilla (spiral).

    Difference between ectomycorrhizal and arbuscular mycorrhizal fungi

    Ectomycorrhizal fungi form a sheath around plant roots, while arbuscular mycorrhizal fungi penetrate the root cells, forming arbuscules.
