Reproduction in Fungi

Q.

How do algae reproduce?

Q.

Why are only 8 ascospores produced in ascomycetes?

Q. Given below are assertions and reason. Point out:
A. If both are true with reason being the correct explanation
B. Both true but reason not correct explanation
C. Assertion is true but reason is wrong
D. Both assertion and reason are wrong

Assertion: As we go from the lower to the higher forms of the fungal members, there is a decrease in the complexity of the sexual apparatus.
Reason: Sexual reproduction involves plasmogamy, karyogamy and meiosis.
