1.7 The Fungi Flashcards
Yeasts characteristics
Facultative anaerobic
Reproduce asexually, often by budding
Reproduce sexually by formation of spores
Macrofungi characteristics
Mushrooms, Puffballs, Truffles, and Shelves
What are Rusts?
produce spots on leaves and stems
What are smuts?
affect seeds and fruits of plants
Characteristics of Fungi?
Cell wall made of chitin (NAG polymer ) Heterotrophic (mostly saprophytic) Mostly aerobic Nonmotile Vary in the types of spores produced Habitat Must have suitable pH, moisture, temperature, and organic nutrients Primarily terrestrial with some aquatic
Mycelium
A mass of Hypae
Hypha
May be septate or coenocytic (nonseptate)
May be aerial or vegetative
Hypha
May be septate or coenocytic (nonseptate)
May be aerial or vegetative
Sporocarp (Mushroom)
organized hyphae designed for spore production
Importance of fungi
Beneficial impact
Decomposers
Production of fermented foods and beverages, steroids, antibiotics and other drugs
Used as model eukaryotic organisms
Detrimental impact: major cause of plant, animal, and human diseases
Division Ascomycota is also known as?
Sac fungi
Division Basidiomycota is also known as?
Club Fungi (mushrooms)
Division Zygomycota iincludes?
spores
Division Deuteromycota known as
(Fungi Imperfectii)
Lack sexual reproduction
Produce asexual spores on conidia
Mycorrhizae is
Relationship between roots of a plant and a fungus
Fungi obtain nutrients for plant and increase root surface area
Plant produces sugars for the fungus
