Where are spores produced for asexual reproduction?
sporangium
One of the most important criteria was the formation of spores and their morphology. Sporangiospores are formed endogenously in a sporangium via cytoplasmic cleavage in the zygomycetes. Motile, flagellated spores of the chytridiomycetes are called zoospores and the term conidium is used for an asexual, nonmotile (cf.
Where the spores are produced?
Spores are most conspicuous in the non-seed-bearing plants, including liverworts, hornworts, mosses, and ferns. In these lower plants, as in fungi, the spores function much like seeds. In general, the parent plant sheds the spores locally; the spore-generating organs are frequently located on the undersides of leaves.
Where are spores produced in bryophytes?
Inside the sporangium, haploid spores are produced by meiosis. These are dispersed, most commonly by wind, and if they land in a suitable environment can develop into a new gametophyte.
Which plants reproduce asexually by spore formation?
The bread mould or Rhizopus plant undergoes asexual reproduction using spores. Spores are resistant to adverse environmental conditions. Though spores are present in the environment, fungus does not grow on dry surfaces.
Which is asexual spore in fungi?
Sporangiospore: These asexual spore are produced in a sac like structure called sporangia (singular;saprangium). Sporangium are produced at the end of special aerial hyphae called sporangiophore.
How are spores produced in bryophytes?
Bryophytes have neither pollen nor flowers and rely on water to carry the male gametes (the sperm) to the female gametes (the eggs). The spore capsules are produced after the sperm have fertilized the eggs. A spore capsule is part of the sporophyte, which develops from a fertilized egg.
Do bryophytes reproduce asexually?
Asexual reproduction s. l. and the formation of asexual diaspores therefore is a remarkable feature and widespread in bryophytes. In nearly no other plant group asexual reproduction is so important than in bryophytes. A great number of bryophyte species, especially dioicous ones, reproduce exclusively asexually.
Where are spores formed in fungi?
It produces spores in saclike structures called asci. The more primitive fungi produce spores in sporangia, which are saclike sporophores whose entire cytoplasmic contents cleave into spores, called sporangiospores. Thus, they differ from more advanced fungi in that their asexual spores are endogenous.
