Family Batrachospermaceae: This family includes algae whose plant body is of soft, thick, gelatinous branched thallus differentiated into structures resembling nodes and internodes. Branches arise in whorls from the nodes. Asexual reproduction is by monospores and sexual reproduction oogamous by the development of carpogonia and spermatangia. Zygotic nucleus, divides [...]
In this article we will discuss about the reproduction in pennales. This will also help you to draw the structure and diagram of reproduction in pennales. Diatom cells multiply usually by a peculiar method of cell division. An increase in the volume of the frustule results in a slight separation of the valves which is followed by mitotic division of [...]
