Click for a diagram of Cosmarium. Darkfield, x1500 Cosmarium Corda ex Ralfs: From Greek cosmarion, small ornament: Cosmarium is a single-celled placoderm desmid. The cells are deeply divided in the middle by a short isthmus that contains the nucleus. The two semicells are rounded in front view and flattened, oval, or elliptic in side view Joseph F. Gerrath, in Freshwater Algae of North America, 2003 Cosmocladium Brébisson (Fig. 30). This is one of the few desmid genera that is considered to be colonial. Cells are essentially identical in form to some smooth-walled Cosmarium, that is, they are biradiate with a narrow or broad isthmus.There is one chloroplast per semicell and it contains a central pyrenoid ADVERTISEMENTS: In this article we will discuss about the cell structures in algae with the help of diagrams.

Other characteristic features of Kingdom Protista are as follows: These are usually aquatic, present in the soil or in areas with moisture. Most protist species are unicellular organisms, however, there are a few multicellular protists such as kelp. Some species of kelp grow so large that they exceed over 100 feet in height The emergence of embryophytes from their charophyte-like ancestor is estimated to have occurred 476-432 MYA. During the adaptation to land, embryophytes evolved to have sporic meiosis; whereas charophyte algae undergo zygotic meiosis. The transition to land required the embryophytes to develop specialized tissues and a cuticle to survive drier terrestrial environments. This transition resulted.
