Biology Question on biological classification
Which of the following does not apply to ascomycetes?
Mycelium is coenocytic and aseptate
Commonly known as sac fungi
Asexual spores called conidia are produced exogenously
Sexual spores called ascospores are produced endogenously
Mycelium is coenocytic and aseptate
Solution
Ascomycetes include pigmented moulds, powdery mildews, yeasts, cup fungi, morels and truffles. They have septate hyphae with cell wall containing chitin or fungal cellulose. Nutritionally they are saprophytic, decomposers, parasitic or coprophilous. Asexual reproduction occurs by budding, fission, oidia stage and through exogenously produced conidia. Sexual reproduction takes place by gametic fusion, gametangial contact and autogamy. Ascus (sac) a sporangial sac peculiar to Ascomycetes is formed and hence the group is also called sac fungi.
