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.
Thallus (pl.: thalli), from Latinized Greek θαλλός (thallos), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria.
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 ...
The thallus length ranges from 1.9 –36 cm with a mean length of 18.6 cm. The thallus width ranges from 0.2 to 4.8 cm with a mean width of 1.4 cm. [5] Ulva linza can be distinguished by its smooth thallus, most with a ruffled margin. [5] Ulva linza can tolerate a wide range of salinities and water qualities. [6]
Each axis connects each frond to a creeping stolon with a diameter of 2 to 2.5 mm (0.079 to 0.098 in) and a length of up to 2 metres (7 ft). Stolons are branched out to slim points and rhizoids then form from bottom surface [ 1 ] these fork and penetrate the sandy substrate firmly anchoring the seaweed to the seafloor.
A byssoid lichen has a wispy, cottony or teased wool appearance due to the loosely woven hyphae in its thallus. [13] It has no outer cortex. [14] Lichens with this growth type can be split into two types. In one type, the thallus is dominated by fungal hyphae, with a photobiont – typically a coccoid green alga – sprinkled throughout. In the ...
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.
