Does Cladophora have motile male gametes?

Does Blue green algae have motile gametes?

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. … But, they are characterized by the absence of motile spores or gametes.

Does Cladophora produce morphologically similar gametes?

In Cladophora reproduction is isogamous. Isogamy, shown in figure (i) involves the fusion of gametes which do not differ morphologically but may be different physiologically. Such gametes are called isogametes.

In which organisms gametes are motile?

Gamete Transfer – in majority of organisms, male gametes are motile and females gametes are non-motile, except in fungi and algae in which both gametes are motile. In simple plants like algae, fungi, bryophytes and pteridophytes water is the medium through which male and female gametes moves.

Do red algae have motile male gametes?

Red algae happen to represent a slight variation of oogamy in that they actually have both non-motile male and female gametes.

In which plants male gametes are motile?

Riccia, Dryopteris and Cycas.

Are male gametes non motile in bryophytes?

As angiosperms and gymnosperm have non motile male gamete while algae, bryo do have motile..

Is Cladophora branched or unbranched?

Unbranched filaments: Image shows Ulothrix which is an unbranched filamentous algae. Since, these filaments have no extensions, it is an unbranched filament. Branched Filaments: Image shows Cladophora which is a branched filamentous algae. Since, the filaments have extensions they are branched filaments.

Why are gametes of Cladophora termed as Isogametes?

The formation of male and female gamete is known as gametogenesis. Gametes are haploid in nature. … When the male and female gamete cannot be differentiated morphologically, the gametes are known as homogametes or isogametes. For example, Cladophora (an algae).

What is the difference between Cladophora and Chlamydomonas?

Chlamydomonas is a green algae found all over the world in soil, marine water, fresh water and even in snow. … Cladophora is a genus of green alga. It is a filamentous green alga which often grows attached to some solid substance.

Is male gamete motile?

The non-flagellated male gamete is free and vigorously motile, propelled by pseudopodia.

Which organisms both male and female gametes are motile?

Dear student, In some organisms like fungi and algae both male and female gametes are motile. The male gametes need a medium through which it can move and can reach the female gamete. In plants like algae, bryophytes and pteridophytes water serve as the medium through which gamete transfer takes place.

In which algae both male and female gametes are motile?

In some species of fungi and algae, female and male gametes are motile and almost identical. Higher animals, plants, and some species of fungi and algae show a particular type of anisogamy known as oogamy. In oogamy, the female gamete is much larger than the male sex cell, and it is non-motile.
