Micrasterias
''Micrasterias'' is a unicellular green alga of the order Desmidiales. Its species vary in size reaching up to hundreds of microns. ''Micrasterias'' displays a bilateral symmetry, with two mirror image semi-cells joined by a narrow isthmus containing the nucleus of the organism. This dual semi-cell structure is unique to the group of green algae to which ''Micrasterias'' belongs. Each semi-cell contains a single large chloroplast, the site of photosynthesis for ''Micrasterias''. Chloroplasts within Micrasterias contain chlorophyll a and chlorophyll b and the enzymes required for photosynthesis. The sugar created is used to provide energy for the organism or, if not used, taken up by many small round pyrenoids which are embedded in the chloroplast. They convert the sugar to a starch for storage. ''Micrasterias'' can produce both asexually and sexually. Asexual reproduction occurs via mitosis. When this occurs the genetic material of ''Micrasterias'' is duplicated and two small se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desmidiales
Desmidiales, commonly called desmids (''Gr.'' ''desmos'', bond or chain), are an order in the Charophyta, a division of green algae in which the land plants (Embryophyta) emerged. Or in other words, Desmid, (order Desmidiales), order of single-celled (sometimes filamentous or colonial) microscopic green algae. Desmids are sometimes treated as a family (Desmidiaceae) of the order Zygnematales. The desmids belong to the class Zygnematophyceae. Although they are sometimes grouped together as a single family Desmidiaceae, most classifications recognize three to five families, either within the order Zygnematales or as their own order Desmidiales. The Desmidiales comprise around 40 genera and 5,000 to 6,000 species, found mostly but not exclusively in fresh water. Many species may be found in the fissures between patches of sphagnum moss in marshes. With a pH level of approximately 4.0, sphagnum peat provides the ideal environment for this flora.

The ...br>webpage on Desmidium Data extracted from the Morphology ''Desmidium'' is one of the filamentous desmid genera characterized by rather firm intercellular connections. Cells connect to adjoining cells at the flat, apical face of the cells. The cells can be longer or shorter than wide. A median constriction of the cells may appear either as distinct or faint. Desmidium cell walls are smooth with multiple side-by-side or scattered pores. Every semicell contains one stellate chloroplast. Typically cells are oval in shape or have a three to five angle. Angles of the cell are often off-balance on each semicell. This creates a heli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euastrum

Description It is made of two, symmetrical semicells. They are usually longer than wide and are wavy and lobed. On the ends of the semicells, there is a notch. The cell wall A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mech ... may have "protuberances;" however, they are hard to see.
