I would like to give a more detailed explanation on this photo for the student.

This photo can help illustrate the sexual reproduction of this Morchella sp. We can see that each ascus is having 8 ascospores. And the ascoscpores are actually haploid.

The nuclei from the dikaryotic ascus (n+n) will first have karyogamy (nuclear fusion) to form diploid nucleus (2n), then it will further undergo meiosis to form 4 haploid nuclei (n), the 4 haploid nuclei will further undergo mitosis, and each nucleus is carried by each of the ascospores formed eventually. At the end, 8 ascospore will be formed and they are all haploid (n)

It would be better for the students to put a box to encircle the structure for other students to have better observation.

Here leave a question for students : Plasmogamy of ascomycetes is resulted from the fusion of two different structure from mycelia with different mating type, can you name those two structure?
