Question

Write some characteristics of duetaromycetes

Answer 1

Answer:

duetaromycetes is come under kingdom fungi

it is commonly called imperfect fungi

it lack sexual reproduction

it reproduces only asexually

Answer 2

Explanation:

The last group of fungi we will be discussing is the Deuteromycota. Because members of this group lack a sexual stage, they are often referred to as imperfect fungi ( or formally the Fungi Imperfecti). Deuteromycota is referred to as form-phylum because the divisions within the group are based on morphology and not on common phylogenetic background. It is thus considered an artificial grouping. There are approximately 17,000 species in this form-phylum but this number is continuously decreasing as more of the teleomorphic stages are being associated with the anamorphic stages. In addition, molecular methods are being used to elucidate the relatedness of the different fungal species in this group. Most Deuteromycota have a well-developed, septate mycelium with distinct conidiophores but some have a unicellular thallus. With the exception of one group, all members reproduce by means of special spores known as conidia. A few imperfect fungi lack conidia and form only sclerotia. There is a tremendous variety of morphologically different conidia produced in the form- phylum Deuteromycota. Conidia may be spherical, ovoid, elongated , star-shaped and so on. They may be one-celled to many-celled, with either transverse septa or both transverse and longitudinal septa. In addition, conidia may be hyaline or colored. These conidial characteristics are the basis for the artificial classification. Members of this group are mostly saprobes, but some are parasitic on plants and animals, including man.

Deuteromycetes are:

1. Ascomycetes with no sexual stage. Exceptions:

Vegetative stage is a plasmodium

Any fungus with sporangia and sporangiospores

Any fungus with clamp connections and dolipore septa

Any asexual stage of a rust

2. Ascomycetes for which the sexual stage is unknown

3. Ascomycetes for which sexual stage and asexual stages are not associated
