In this article we will discuss about the thallus structure of polysiphonia with the help of suitable diagrams. The thallus is filamentous, red or purple red in colour. The thallus is multi-axial and all cells are connected by pit connections hence, the name given is Polysiphonia. Due to continuous branching and re-branching the thallus has feathery appearance (Fig. 1A). The [...]
In this article we will discuss about the asexual and sexual reproductive structure of ectocarpus. Asexual Reproduction of Ectocarpus: 1. Reproduction is by asexual as well as sexual methÂods. 2. Asexual reproduction is with the help of zoospores. 3. Zoospores are haploid as well as diploid. 4. Haploid zoospores are formed in unilocular sporangia while the diploid zoospores in plurilocular [...]
In this article we will discuss about the asexual and sexual reproductive structure of vaucheria. Asexual Reproduction of Vaucheria: Various means of asexual reproduction are: (a) Zoospores, (b) Aplanospores, (c) Hypnospores, (d) Cyst formation. Zoospore: 1. Zoospore is formed singly in the zoosporangium, formed in the terminal part of the thallus (Fig. 31). 2. Zoosporangium is a club-shaped swollen structure [...]
