Which one of the following matches is correct?
- Mucor – Reproduction by conjugation – Ascomycetes
- Agaricus – Parasitic fungus – Basidiomycetes
- Phytophthora – Aseptate mycelium – Basidiomycetes
- Alternaria – Sexual reproduction absent – Deuteromycetes
Answer
(4) Alternaria – Sexual reproduction absent – Deuteromycetes
Solution
As per NCERT, the members of Deuteromycetes are called imperfect fungi because only their asexual or vegetative phases are known (sexual reproduction absent), e.g. Alternaria, Colletotrichum and Trichoderma.
⇒ (1) Mucor reproduces sexually by conjugation but belongs to Phycomycetes, not Ascomycetes.
⇒ (2) Agaricus (mushroom) is a Basidiomycete but a saprophyte, not a parasite.
⇒ (3) Phytophthora has aseptate mycelium but is placed in Phycomycetes, not Basidiomycetes.
∴ Only Alternaria – sexual reproduction absent – Deuteromycetes is correctly matched.
Answer: (4)
