Question

Differentiate between sporangiospores and conidiospores?

Answer 1

Hint: Sporangiospores are produced within a sac-like structure called the sporangia, it develops on sporangiophores. Conidia are produced on conidiophores.

Step by step answer:Conidiospores:- Conidia are the asexual, non-motile spores. They are made by mitosis. Conidia are not enclosed in a protective sac, unlike sporangiospores. Conidia are haploid cells that are identical to the haploid parent. Asexual reproduction in ascomycetes is done by the formation of conidia that are borne on stalks called conidiophores. The morphology of these conidiophores is distinctive between different species and, just before the development of molecular techniques, widely used for identification of species for example Metarhizium.

Sporangiospore:- The asexual propagules is formed inside a sporangium. Sporangiospores can be mostly spherical and also cylindrical, with the help of a process that involves cleavage of the cytoplasm and is named sporangiospores. These spores are thin-walled, hyaline and pale in colour, and globose and ellipsoid in shape. One to 50,000 sporangiospores are to be formed in a single sporangium. When mature, sporangiospores are released by the help of breakdown of the sporangial wall, or if the entire sporangium is dispersed as a unit. Sporangiospores are produced by fungi of the Chytridiomycetes and Zygomycetes, as well the Oomycetes, which is a group of fungi that is unrelated to the true fungi phylogenetically.

Note: Conidiospores are borne externally in chains on an aerial hyphae which is called a conidiophore. sporangiospores are produced within a sporangium on an aerial hyphae which is called a sporangiophore.
