The plant body of an alga is referred to as the thallus, and in this subclass it is filamentous with pseudoparenchymatous development.
This means that the cells that compose the thallus are in a linear arrangement and those that are next to each other are not necessarily the result of the same cellular division.
Florideophyceaealgae are multi cellular, when they grow they do so by producing new cells at the end of branches, apical growth.
The Class Florideophyceae is a diverse group of red alga containing species as seemingly different as the coralline algae and Botryocladia, the sea grapes.
These algae are all united, however, by morphological similarities such as filamentous or pseudoparenchymatous construction, apical cell division, the formation of pit connections, and dioecious gametophytes.
In addition, members of the class Florideophyceae also have carpogonia located on a trichogyne, as well as carpospores that form on gonimoblast filaments.
