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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
