WebEctocarpus is a genus of filamentous brown alga that is a model organism for the genomics of multicellularity.[1] Among possible model organisms in the brown algae, Ectocarpus was selected for the relatively small size of its mature thallus and the speed with which it completes its life cycle.[2][3] The type species for the genus is Ectocarpus siliculosus … Webportion of thallus bearing sporangia (a) Epidermis: Epidermis is composed of one or two layers of small cubical cells. These cells contain many chromatophores. (b) Cortex: It is composed of elongated cells. These cells show variations in their sizes. The cells formed earlier in the growing seasons are larger. Ectocarpus is a genus of filamentous brown alga that is a model organism for the genomics of multicellularity.
