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 classification of phaeophyta. Kylin (1933) divided Phaeophyta into three classes according to the type of life history. Further division of these classes into subclasses, and the arrangement of the orders, may best be understood from the key given below. This classification has received wide recognition for practical purposes although Papenfuss (1951) rejected [...]
In this article we will discuss about the classification of sargassum. Family Sargassaceae: Plants possess flat costate branches or transitional stages to cylindrical branches bearing numerous macroscopic spine-like projections, turbinate foliar organs, or costate leaves, usually with cryptostomata and buoyant air-bladders. Conceptacles are in ordinary branches or in special receptacular branchlet systems. Sexual reproduction is oogamous. Each oogonium produces a [...]
