Does red algae move

Answer 1

a large order of cellular, flowerless, cryptogamic plants, found in the sea (seaweeds), in rivers, laked, marshes, hot springs, and moist places, all over the world. They consist of a brown, red, to green. Flattered, cellular, leaf-like expansion, called a thallus, sometimes stalked, which bears the organs of reproduction. Some have root-like processes by which they are attached to rocks. These do not act like the nourishing roots of flowering plants; they simply fix the plants and enable them to sway about in the water. This is markedly the case with the Laminaries, or large tangles of our coasts. The leafy appendages of seaweeds are called fronds. They vary in size, colour, and consistence. Some of the red and green delicate fronds form beautiful objects when carefully dried and laid out on drawing-paper. In order to dry seaweeds they must be first washed carefully in fresh water to separate saline matters, and then placed within drying-paper and subjected to pressure. Very delicate seaweeds should be floated out in water, drawing-paper being placed under them, and their fronds being carefully arranged on the paper before they are raised out of the water. They must then be dried partially in the air, and afterwards under pressure between sheets of drying paper.

Seaweeds are composed entirely of cells, which in some instances become elongated so as to have the appearance of tubes. Some Algae are uni-cellular, that is, are composed of a single cell, as occurs in some Desmidiease, as Closterium. At other times they are composed of numerous cells, which are kept together by a gelatinous matter, but separating easily from each other so as to have an independent existence. This is observed in the red snow plant (Protococcus or Palmella nivalis). The cells of seaweeds are sometimes joined together so as to form a linear series, and to give them a thread-like appearance; and in such a case, when the divisions between the cells are marked, the whole appears like a beaded necklace of cells. When the cells are united both lengthwise and laterally they then form an expanded flat frond. In some instances the frond is gelatinous.

The movement of red algae is basically accomplished only with the movement of water currents. This means that the algae does not swim or move on its own.
