How are clamps formed?
A clamp connection is a hook-like structure formed by growing hyphal cells of certain fungi. It is created to ensure that each cell, or segment of hypha separated by septa (cross walls), receives a set of differing nuclei, which are obtained through mating of hyphae of differing sexual types.
Which group has characteristic of formation of clamp connection?
So, the correct answer is ‘ Basidiomycetes’.
What is the function of the clamp connection in the basidiomycota?
Hint: Clamp connection is a structure that resembles a hook formed from hyphal cells of some types of fungi. The major function of this connection is to make sure that every cell or segment of hypha is separated by septa.
What do you mean by clamp connection?
Definition of clamp connection : a bulgelike hyphal outgrowth in many basidiomycetous fungi that is formed at cell division over the cross wall between the two daughter cells and provides a connection through which one of the involved nuclei may pass in order to maintain the binucleate state of the resulting cells.
What is Crozier formation?
A crozier is an anatomical feature of many fungi in the phylum Ascomycota that forms at the base of asci and looks like a hook-topped shepherd’s staff or stylized religious crosier. Croziers resemble and function similarly to clamp connections on the dikaryotic hyphae of Basidiomycota.
How do zygomycetes obtain nutrients?
Most zygomycetes feed on dead or decaying plant and animal material. Expose some bread to air for a few hours and it very likely will become infected with spores of a zygomycete.
What is fungi stroma?
stroma, plural stromata, in fungi (kingdom Fungi), cushionlike plate of solid mycelium (masses of filaments that form the body of a typical fungus) formed by many members. Vegetative and reproductive structures are borne on or in them.
What is perfect stage of fungus?
The sexual stage is called the perfect stage of a fungus.
How basidiocarp is formed?
basidiocarp, also called basidioma, in fungi, a large sporophore, or fruiting body, in which sexually produced spores are formed on the surface of club-shaped structures (basidia).
Is basidiocarp a membrane structure?
In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi. In more complex basidiocarps, there is differentiation into a stipe, a pileus, and/or various types of hymenophores.
What is the structure of zygomycetes?
Zygomycetes have a thallus of coenocytic hyphae in which the nuclei are haploid when the organism is in the vegetative stage. The fungi usually reproduce asexually by producing sporangiospores. The black tips of bread mold, Rhizopus stolonifer, are the swollen sporangia packed with black spores.
