What is Sporangiophore in biology?

Definition of sporangiophore : a stalk or similar structure bearing sporangia.

What is Sporangiophore in botany?

sporangiophore (plural sporangiophores) (botany) A receptacle in ferns which bears the sporangia, usually a stalk, but sometimes a scale (as in horsetails). (mycology) A special type of hypha that bears sporangia on the tip.

What is the purpose of Sporangiophore?

The spore-producing cells within sporangia are called sporangiophores. When mature, sporangia release their spores through an opening or pore. The sporangium is involved in asexual reproduction and can play an indirect role in sexual reproduction in certain fungi phyla.

What is the structure of Sporangiophore?

…of the strobilus are called sporangiophores; each consists of a stalk bearing a flattened disk at its apex, on the lower edge of which is a ring of 5 to 10 sporangia, each one opening and shedding spores by a longitudinal slit on its inner side.

Is Sporangiophore and hyphae same?

Sporangiophores are hyphae that are simple, unbranched tubular threads with rounded sporangia at their ends. For asexual reproduction, sporangia develop non-motile multinucleate spores.

How is Sporangiophore formed?

Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. The haploid nuclei within the zygosporangium then fuse into diploid nuclei. When conditions improve the zygosporangium germinates, undergoes meiosis and produces a sporangium, which releases spores.

What is Sporangiophore in fungi?

Noun. 1. sporangiophore – stalk bearing one or more sporangia. stalk, stem – a slender or elongated structure that supports a plant or fungus or a plant part or plant organ.

What is the meaning of Sporophytic?

sporophyte, in plants and certain algae, the nonsexual phase (or an individual representing the phase) in the alternation of generations—a phenomenon in which two distinct phases occur in the life history of the organism, each phase producing the other. The sexual phase is the gametophyte.

What is the difference between a Sporangiophore and a conidiophore?

what is the difference between a sporangiophore and a conidiophore? A sporangiophore producesits spores in an enclosure; a conidiophore does not. A mushroom begins life as a small my celium that grows from spores which have come from another mushroom.
