A. Phycomycetes  ✓ Correct
B. Deuteromycetes
C. Basidiomycetes
D. Ascomycetes
Solution: Phycomycetes (e.g. Mucor, Rhizopus, Albugo) have coenocytic hyphae and asexual zoospores/aplanospores.

A. Phycomycetes
B. Deuteromycetes
C. Basidiomycetes
D. Ascomycetes  ✓ Correct
Solution: Ascomycetes (e.g. Aspergillus, Penicillium, yeast) form ascospores within an ascus; many are of great commercial value.

A. Ascomycetes
B. Basidiomycetes  ✓ Correct
C. Slime moulds
D. Phycomycetes
Solution: Basidiomycetes produce basidiospores on club-shaped basidia; they include the common mushrooms and rusts/smuts.

A. Only their asexual (or vegetative) phase is known  ✓ Correct
B. They lack a cell wall
C. They are prokaryotic
D. They cannot reproduce at all

Q7 — Kingdom Fungi · hard · theory
In fungi, a temporary dikaryotic (n + n) condition arises during sexual reproduction because:

Q14 — Kingdom Fungi · medium · numerical
Assertion (A): In Ascomycetes the sexual spores are produced endogenously inside a sac-like ascus. Reason (R): In Basidiomycetes the sexual spores are borne exogenously on a club-shaped basidium.
A. A is false but R is true
B. A is true but R is false
C. Both A and R are true and R is the correct explanation of A
D. Both A and R are true but R is not the correct explanation of A  ✓ Correct
Solution: Both facts are correct, but they describe two different classes independently; R is not an explanation of A.
Q15 — Kingdom Fungi · medium · numerical
Which feature is characteristic of the Phycomycetes, the so-called "lower fungi"?
