Does Cladophora have motile male gametes?
Cladophora is an example of algae that produces motile homogametes. … Volvox and Fucus are examples of oogamous reproduction, where the female gamete is large, non-motile and the male gamete is small, motile.
What type of growth form does Cladophora exhibit?
Coarse in appearance, with regular-branching filaments that have cross walls separating multinucleate segments, Cladophora grows in the form of a tuft or ball with filaments that may range up to 13 cm (5 inches) in length. Asexual reproduction involves small motile spores (zoospores) with four flagella.
How do Cladophora reproduce?
Cladophora reproduces by vegetative, asexual and sexual methods. In some species during vegetative reproduction the erect portion of the thallus dies back, while the rhizoidal system persists. Many of the cells of the rhizoid become swollen and assume pear-shaped form.
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.
Does Cladophora produce morphologically similar type of fusing 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. … The common type of anisogamy is oogamy, which involves fusion of large immotile female gamete and small motile male gamete.
Which of the following algae produces isogametes?
Ulothrix and Spirogyra produce isogametes.
Why are gametes of Cladophora termed as Isogametes?
When the male and female gamete cannot be differentiated morphologically, the gametes are known as homogametes or isogametes. For example, Cladophora (an algae). When male and female gamete can be differentiated morphologically, such gametes are known as heterogametes.
What is the phylum of Cladophora?
The Rhodophyta, Phaeophyta and Clorophyta constitute the “algae” (singular alga) They include motile unicellular (Chlamydomonas), motile multicellular (Volvox) and static multicellular types (Cladophora, Spirogyra and “seaweeds”).
Is Cladophora a bacteria?
Cladophora glomerata, a macrophytic green alga, is commonly found in the Great Lakes, and significant accumulations occur along shorelines during the summer months. Recently, Cladophora has been shown to harbor high densities of the fecal indicator bacteria Escherichia coli and enterococci.
What domain is Cladophora?
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 Cladophora invasive?
Cladophora is a green algae found naturally along the Great Lakes coastlines. … These invasive species activities increase the availability of phosphorus for Cladophora and increasing water clarity.
How do you identify Cladophora?
Cladophora appears as tough filaments or green turfs in areas of high light and poor flow. They are tougher than ordinary types of ‘hair’ algae and do not break apart as easily as other filamentous green algae. They can be identified by their distinctive smell.
How Gametogenesis of Cladophora is different from that of Fucus?
The haploid gametophyte produces haploid gametes by mitosis and the diploid sporophyte produces haploid spores by meiosis. The only visible difference between the gametes and spores of Cladophora is that the gametes have two flagella and the spores have four.
