Define general characteristic of division Algae and define general characteristic 4 of Chlorophyceae, Phaeophyceae, and Rhodophycea​

Answer 1

Answer:

Eubacterium -a bacterium of a large group typically having simple cells with rigid cell walls and often flagella for movement. The group comprises the ‘true’ bacteria and cyanobacteria, as distinct from archaea

Chlorophyceae- The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. For example, the chlorophycean CW clade, and chlorophycean DO clade, are defined by the arrangement of their flagella.

Rhodhophycea - a class of chiefly marine multicellular algae (division Rhodophyta) comprising algae in which red phycoerythrin and sometimes blue phycocyanin mask the chlorophyll, in which no motile form or stage exists, and in which there is a well-marked and often complex alternation of generations — compare red alga.

phaeophyceae - a class of lower plants that comprises the brown algae.
