pollen grain is the carrier of non-motile gamete in  Riccia  cycas  wolffia  Pteris … Cycas belongs to gymnosperms. These are seed bearing plants and produce non motile gametes. The pollen grain acts as carrier of non motile male gamete and transfers it to the female flower for fertilisation to take place.
Which plants produce motile male gametes?
While absent from flowering and most cone-bearing plants, motile cells are found in less derived taxa, including bryophytes (mosses, liverworts and hornworts), pteridophytes (lycophytes and ferns) and some seed plants (Ginkgo and cycads). …
In which algae non-motile male gametes are formed?
In algae, haploid cells act directly as gametophytes as they produce gametes. Option A Blue green algae: Blue green algae or Cyanophyceae reproduce through simple division or fragmentation or non-motile spores. Also, they do not reveal any motile phase during the life cycle.
Which plants produce non-motile male gametes?
The male and female gametes are produced by flowers. Flowers mainly have petals, sepals, stamen, and pistil. Stamen is the male reproductive part and has anther and filament. The anther produces and stores the pollen which is the male gamete and is non-motile.
Are male gametes of Pteridophytes motile?
Bryophytes and Pteridophytes require water for fertilization and have motile male gametes.
Does marchantia produce motile male gametes?
Marchantia polymorpha L. is a model basal land plant with sexual reproduction involving an egg cell and bi-flagellated motile sperm.
Does marchantia have motile male gametes?
Chara is similar to Marchantia as both have Nonmotile male gametesâ€‹. Chara and Marchantia both species possess on motile gametes and they need means of pollination for fusion.
Is male gamete non-motile in algae?
As angiosperms and gymnosperm have non motile male gamete while algae, bryo do have motile..
Does porphyra have motile gametes?
Porphyra displays a heteromorphic alternation of generations. The thallus we see is the haploid generation; it can reproduce asexually by forming spores which grow to replicate the original thallus. … The female gametes while still on the thallus are fertilized by the released male gametes, which are non-motile.
What are non-motile gametes?
Non motile gametes are produced during sexual reproduction in oogamy process. Oogamy is a form of sexual reproduction. It is a form of anisogamy in which the female gamete is larger than the male gamete and is non-motile.
Does Fucus have motile male gametes?
Fucus, the female gamete is large and non-motile whereas male gamete is small and motile .
Are male gametes motile in bryophytes?
In bryophytes and pteridophytes, transport of male gametes requires. … Male gametes are motile in most cases, and female gametes are fixed. Both forms of gametes are movable in a few algae and fungi.
Are male gametes motile in Cycas?
Cycads are dioecious, with separate male and female plants, and fertilisation is effected by motile male gametes—so-called zooidogamous reproduction.
What is required for transport of male gametes in bryophytes and pteridophytes?
In bryophytes and pteridophytes, transport of male gamete requires water. The male gametes of bryophytes and pteridophytes are motile and can swim through water with the help of their flagella. They are transferred to the female reproductive organ for fertilsation.
