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]
Siphonocladus tropicus showing segregative cell division. Siphonocladus is a small genus of green algae in the family Siphonocladaceae. [1] [2] The algal body 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.
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.
The thallus of Dictyota dichotoma grows in tufts and is a yellowish-brown or greenish colour, with a faint bluish iridescence when underwater. It forms membranous, flattened, dichotomously-branching fronds up to 25 cm (10 in) long and 10 mm (0.4 in) wide.
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.
