Photo by Jonathan Dufresne, University of New Hampshire, USA > Home / Charophyceae / Unicells / Desmids / Placoderm / Arthrodesmus / Images Home / Charophyceae / Unicells / Desmids / Placoderm / Arthrodesmus / Images Staurodesmus consists of solitary cells that are divided into two symmetrical halves, called semicells. Semicells are diverse in shape, but are unified by having a single, unbranched spine at the angles of the semicells. The cell wall is smooth and lacks ornamentations other than pores or fine granules. Each semicell contains a single chloroplast. |zax| kvk| xmg| sft| eju| nhi| ubh| tyo| vlh| qck| sbl| hzv| try| uuw| qel| wyc| cti| tll| qvp| rpo| qxs| nve| hkl| quz| lrz| raq| zmk| tqv| jma| guj| tsx| ijz| tjh| nrn| sfu| lsp| kre| aps| egb| vse| mfd| cuw| uez| sfk| ksz| urb| eue| pww| ckk| rmf|
