The life history of some of them is quite complex. They have spores, but their spores and likewise their gametes have no cilia, a curious feature since these plants are wholly aquatic. The female sex organ is multicellular and more complex than the sex organs of the Brown Algae. Several forms of the Red Algae are of economic importance. Some are used as food, being dried and kept for long periods The gelatinous material obtained from Red Algae forms a delicacy.
