Question

Which one among the following is not an asexual spore in fungi?

• A. Conidia
• B. Zoospores
• C. Sporangiospores
• D. Basidiospores

Answer 1

The correct option is D

Basidiospores

The correct option is D.

Explanation of correct option:

1. The sexual and asexual phases of Basidiomycota's life cycle can be distinguished.
2. Sexual reproduction involves the usage of basidiospores.
3. Basidiospore is a sexual spore produced by fungi basidiomycetes.
4. Basidiospores are always produced externally on a structure called a basidium. Basidiospores are produced exogenously.

Explanation of incorrect option:

Option A:

1. Conidium is an asexual reproductive spore generated by mushrooms (order Fungi) at the tip or side of hyphae (filaments that make up a normal fungus' body) or on specific spore-producing structures called conidiophores.

Option B:

1. A zoospore is a motile asexual spore that moves by using its flagellum.
2. These spores, also known as swarm spores, are produced by various protists, bacteria, and fungi in order to reproduce.

Option C:

1. Asexual spores generated inside a walled sporangium are known as sporangiospores.
2. Sporangiospores include zygomycetes' spores, which are exposed to the air after the mature sporangial wall splits, and chytrids' motile zoospores, which are released into water from their zoosporangia.

Final answer: Basidiospores are not an asexual spore in fungi
