A kelp, for example, may have its thallus divided into three regions. The parts of a kelp thallus include the holdfast (anchor), stipe (supports the blades) and the blades (for photosynthesis). [2] The thallus of a fungus is usually called a mycelium. The term thallus is also commonly used to refer to the vegetative body of a lichen.
Siphonocladus is a small genus of green algae in the family Siphonocladaceae. [ 1 ] [ 2 ] The algal body ( thallus ) is composed of long, club-shaped cells that divide by segregative cell division , followed by the formation of branches that break through the mother cell.
Mastophora is a genus of thalloid alga comprising four species. The dimerous, crustose thalli comprise two groups of filaments. The bulk of the thallus is made of erect filaments, which may be one or many cells long.
Several kelp laminae. The lamina or blade in macroscopic algae, like seaweed, is a generally flattened structure that typically forms the principal bulk of the thallus. [1] It is often developed into specialised organs such as flotation bladders and reproductive organs.
Brown algae have many unique characteristics in terms of their metabolism and cell biology. Ergo, brown algae and in particular, E. siliculosus, are often used for explorative research. Its genome was the first brown macroalgal genome to be sequenced, with the expectation that E. siliculosus will serve as a genetic and genomic model for brown ...
Caulerpa is coenocytic, meaning it has a multinucleate thallus organization. It is also siphonous, meaning unlike other algae, the thallus and the nuclei are not separated by cell walls. They are instead one long mass of protoplasm surrounded by a single cell wall. [12]
The thallus is filamentous, highly branched, and may be packed into a mass. It is coenocytic , having multi-nucleate cells consisting of cytoplasm contained within a cylindrical cell wall . There are no septae , and the many discoid chloroplasts, nuclei and other organelles are free to move through the organism.
Lichenomphalia is both a basidiolichen and an agaric genus. [2] [3] Most of the species have inconspicuous lichenized thalli that consist of scattered, small, loose, nearly microscopic green balls or foliose small flakes containing single-celled green algae in the genus Coccomyxa, [4] all interconnected by a loose network of hyphae.
