Question 7 Mark the phylum that produces each of the following types of spores: DA M8 sexual spores in a sac-like sporangium A. Ascomycota Bv14 sexual spores that pinch off the end of the cell in which meiosis took place B. Basidiomycota B v 8 sexual spores that result from the division of a single diploid nucleus c. Cota (meiosis followed by mitosis) C a large number of sexual spores that result from meiotic division of several diploid nuclei in the same sporangium

Solution

In Ascomycota 8 spores are produced generally. In about 99% species, 8 spores have been reported. These sexual spores are known as ‘ascospores’. Sporangium contains ‘sporangiospores’, which are asexual. So, your statement is incorrect. The correct statement would be, \"8 sexual spores in an ascus.\"

In Basidiomycota, 4 sexual spores are produced. These are produced in ‘basidium’. These spores are produced externally. However, the number of spores varies from 1 to 8. So, option B and C regarding to Basidiomycota is totally correct.

The Zygomycota is a unique class of fungi. It takes its name from the mode of sexual reproduction which is quite unique. In sexual reproduction, ‘zygospores’ are produced inside Zygosporangia. Sporangium contains asexual spores, not sexual spores. So, your \"C\" statement is totally incorrect.
