In this article we will discuss about the thallus and cell structure of oedogonium with the help of suitable diagrams. Thallus Structure of Oedogonium: The thallus is made of green, multicellular, un-branched filaments. The filament is made of three types of cells (Fig. 1): (i) The lower-most basal cell or holdfast. (ii) The intercalary cells. (iii) The upper-most apical cell. [...]
In this article we will discuss about the process of cell division in oedogonium with the help of diagram. When a cell divides into two daughter cells, two separate processes are involved, one is cell division and the other is cell elongation including the cell walls. In cell division the protoplasm divides, the first sign of which is the division [...]
In this article we will discuss about the vegetative, asexual and sexual methods of reproduction that occur in the life cycle of oedogonium. (i) Vegetative Reproduction: Vegetative reproduction takes place by fragmentation and akinete formation. (A) Fragmentation: Oedogonium filament breaks into many small fragments which have capability to grow into complete filaments under favourable conditions. Fragmentation takes place due to [...]
