In this article we will discuss about the life cycle of ectocarpus, explained with the help of suitable diagrams. Family Ectocarpaceae of Phaeophyta: Plants are filiform and more or less branched, or sub-simple from a creeping, penetrating, or disciform base; generally uniseriate but occasionally some segments in the lower part with one or two longitudinal septa; reproductive organs lateral, replacing [...]
In this article we will discuss about the asexual and sexual reproduction that occurs in the life cycle of ectocarpus. (i) Asexual Reproduction in Ectocarpus: The asexual reproduction takes places with the help of biflagellate zoospores. These zoospores are produced in unilocular and plurilocular sporangia (Fig. 1 B). The sporophytic diploid plant forms two types of sporangia: (a) Unilocular sporangia [...]
In this article we will discuss about the thallus and cell structure of ectocarpus with the help of diagrams. Thallus Structure of Ectocarpus: The plant body is mostly typically heterotrichous and differentiated into (a) creeping or prostrates system and (b) projecting an erect system. In some species one of the two systems may be reduced. In epiphytic forms the prostrate [...]
