Galanthus plicatus Galanthus plicatus Galanthus plicatus is a species of flowering plant in the family Amaryllidaceae, native from Romania, Ukraine and Crimea in eastern Europe to north Turkey and the north-west Caucasus in Asia. "Galanthus plicatus" is a bulbous perennial plant, growing to about 15 cm tall. Its leaves are bluish or greyish green, broader than many other species of "Galanthus", up to 2 cm wide. The leaf edges are folded back away from the upper surface of the leaf, both in bud and after they expand. The nodding white flowers appear in spring and have six white tepals. The outer three
Chlamydomonas nivalis "C. nivalis" is complex, it also helps the algae exploit its niche and survive unfavourable conditions. As a result, "C. nivalis" is one of the best known and studied snow algae. When taking account of the photoprotective effect of its secondary carotenoid, astaxanthin, among the other adaptive mechanisms to its extreme habitat, it can be understood how "C. nivalis" became so dominant in microbial snow algae communities. Green motile offspring are produced in the spring and throughout the summer. They develop into red dormant cysts, the stage where this organism spends most of its life cycle, as the winter season
