difference between oomycetes and zygomycetes

 oomycetes form a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms. They are filamentous, microscopic, absorptive organisms that reproduce both sexually and asexually. Oomycetes occupy both saprophytic and pathogenic lifestyles – and include some of the most notorious pathogens of plants, causing devastating diseases such as late blight of potato and sudden oak death. They are also often referred to aswater molds (or water moulds), although the water-preferring nature which led to that name is not true of most species, which are terrestrial pathogens.

Zygomycota, or zygote fungi, is a phylum of fungi. The name comes fromzygosporangia, where resistant spherical spores are formed during sexual reproduction. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. Some are parasites of plants, insects, and small animals, while others form symbiotic relationships with plants. Zygomycetehyphae may be coenocytic, forming septa only where gametes are formed or to wall off dead hyphae.

Another difference between oomycetes and zygomycetes is that the vegetative state of oomycetes is diploid while the zygomycetes are haploid or dikaryotic. Oomycetes and zygomycetes are microscopic eukaryotic organisms. ... But they are water moulds. Zygomycetes are one major class of phylum Zygomycota which are true fungi.
