What produces the spores?
A
The Sori
B
The Sorus
C
The Sporangium
D
None of the above
Explanation: 

Detailed explanation-1: -The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae.

Detailed explanation-2: -Sporangiospores are spores that are produced in a sporangium (plural: sporangia). A sporangium in fungi (but not mosses and some other organisms) is simply a cell containing spores.

Detailed explanation-3: -A spore is a cell that certain fungi, plants (moss, ferns), and bacteria produce.

Detailed explanation-4: -In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes.
