This Wikipedia article on Spores mentions this:

In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for ....

What is the difference between the sexual spore and asexual spore? Are they any different on basis of formation, diploid or haploid, role in life cycle?

By Sexual Spores, I mean the spores that arise in the sexual reproduction process and similarly for Asexual Spores, i.e. spores which arise in asexual reproduction process.

To add to the context, this image shows the Sexual and Asexual spores in a certain fungi (Mycelium) life cycle.

  • $\begingroup$ @Willk this is not an assignment given by anyone to me. I was in fact studying reproduction in organisms and dug into 'spores', eventually I ended up upon the Wikipedia page on Spore (link mentioned in the question). And was curious between their difference. [I have edited the question now] $\endgroup$ – Cerebral cortex May 6 at 9:32

In the same wikipedia page of spores you cited, you can find that they have said:

Fungi commonly produce spores, as a result of sexual, or asexual, reproduction. Spores are usually haploid..


Vascular plant spores are always haploid.

So, sexual and asexual spores have no difference in ploidy- both are haploid. (There are exceptions- zygospores in fungi are diploid) Now, coming to mode of formation, they are different. For example, in Ascomycetes, sexual ascospores are produced endogenously whereas asexual conidiospores are produced exogenously.

Spores that are formed by the process of meiosis are sexual spores and when formed from mitosis are asexual. The term 'sexual' means meiosis is involved.
