WebSexual reproduction in Spirogyra takes place by conjugation, i.e.the union of two non-motile gametes. Sexual reproduction in Spirogyra can be considered as isogamous type as there is no any differences in the shape of gametes which occurs by the conjugation of non flagellated gametes. However, one of the gametes can be regarded as male as it ... WebUlothrix, genus of filamentous green algae (family Ulotrichaceae) found in marine and fresh waters. Each cell contains a distinct nucleus, a central vacuole, and a large thin chloroplast with at least one pyrenoid. The specialized cell for attachment is called the holdfast, and the filaments are typically unbranched. In most species, all the cells can form reproductive …

WebLateral conjugation is another common method of sexual reproduction in Spirogyra. It takes place in homothallic or monoecious (having male and female reproductive organs in the same individual) species of Spirogyra. lateral conjugation takes place between the adjacent cells of the same filament. The zygospores are usually formed in alternate cells. WebApr 27, 2024 · In spirogyra, any vegetative cell produces the gamete and there are no morphological differences between male and female gametes. Thus morphologically the gametes are isogamous and physiologically anisogamy. Conjugation takes place by two methods: 1. Scalariform conjugation: It occurs between the two filaments of the cell. meaning of palliative medicine

WebFeb 13, 2024 · Spirogyra reproduce sexually through conjugation, which involves the fusing of two gametes of opposing strains. The gamete consists of the entirety of the cell’s protoplasm.

Sargassum – a source of chlorophyll; The correct answer is C. Explanation:- The protoplasmic mass of the male cell rounded to create male gamete, while the protoplasmic mass of the female cell rounded to form female gamete after conjugation tube development. The male is a donor who is actively involved ... WebSexual reproduction- This is commonly observed among Spirogyra and is of isogamous type which means, spores of similar size fuse to form new filaments. Spirogyra reproduce sexually by two types of conjugation – lateral and scalariform. Lateral conjugation: Adjacent cells of single filament function as male and female gametes. meaning of paloma
