What is the Difference Between Oomycetes and Zygomycetes

The main difference between Oomycetes and Zygomycetes is that Oomycetes produce gametangia differentiated into antheridia and oogonia as a result of the sexual process whereas Zygomycetes produce zygosporangia, which is heterokaryotic.

What are the differences between oomycetes and fungi?

† Fungi are haploid or dikaryotic during the major part of their lifecycle, whereas Oomycetes are diploid. ... † Fungi and Oomycetes synthesize lysine by different pathways. The Oomycetes use the a,1-diaminopimelic acid pathway, whereas fungi synthesize this amino acid by the so-called a-aminoadipic acid pathway.

Why is Oomycota called Oomycota?

"Oomycota" means "egg fungi," and refers to the large round oogonia, or structures containing the female gametes, as shown in this picture of the common "water mold" Saprolegnia. Oomycetes are oogamous, producing large non-motile gametes called eggs, and smaller gametes called sperm.

Why are zygomycetes called conjugation fungi?

When the zygospore germinates, it undergoes meiosis and produces haploid spores, which will, in turn, grow into a new organism. This form of sexual reproduction in fungi is called conjugation (although it differs markedly from conjugation in bacteria and protists), giving rise to the name “conjugated fungi”.

Why do the Oomycetes not have photosynthesis?

Ø Both Oomycetes and true fungi have heterotrophic mode of nutrition. Ø Both groups are devoid of chlorophyll pigments and hence they cannot do photosynthesis.

Are Oomycetes Stramenopiles?

They are a large group of protists (over 100,000 species) that include many previously classified as fungi, protozoa, or algae (such as diatoms and kelp). The oomycetes comprise the largest group of non-photosynthesizing stramenopiles. ... Oomycetes are diploid for most of their life cycle, fungi mainly haploid.

What are the characteristics of oomycetes?

Morphological characteristics of oomycetes. One of the most distinguishing characteristics is the production of zoospores produced in sporangia. The anterior flagellum of a zoospore is a tinsel type, while the posterior flagellum is a whiplash type; both are typically attached in a ventral groove (Figure 2).

How do Oomycetes reproduce?

Sexual reproduction in Oomycetes occurs between two dissimilar gametangia: a large round oogonium containing one to several eggs, and a smaller antheridium that fertilizes the oogonium. If the antheridium is located at the side of the oogonium, the arrangement is termed paragynous.

How do Ascomycetes reproduce?

Asexual reproduction. Asexual reproduction is the dominant form of propagation in the Ascomycota, and is responsible for the rapid spread of these fungi into new areas. It occurs through vegetative reproductive spores, the conidia. ... They are typically formed at the ends of specialized hyphae, the conidiophores.

Which is known as conjugation fungi?

When the zygospore germinates, it undergoes meiosis and produces haploid spores, which will, in turn, grow into a new organism. This form of sexual reproduction in fungi is called conjugation (although it differs markedly from conjugation in bacteria and protists), giving rise to the name “conjugated fungi”.

Why Ascomycetes are called sac fungi?

Ascomycetes are called sac fungi because they form a sac like structure called ascus which contains the sexual spores (Ascospores) produced by the fungi.

Do basidiomycota reproduce sexually or asexually?

Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores.
