There is a large cell in the center of the internodes of the main stem and lateral branches, and there is a layer of long and thin cells outside, which is called cortical cells, and the nodes are composed of many small cells. There are "leaves" distributed on the lateral branches, which are unicellular. In the process of reproduction, egg shaped oocysts are formed in the axillary of "leaf", under which there are spherical sperm sacs for sexual reproduction and vegetative reproduction.
