Which is a type of fern, Adiantum or Hylomecon?
Hylomecon Hylomecon vernalis, also known as the forest poppy, is a poppy of the Far East, ranging from Manchuria to Japan.
Phaeodactylum tricornutum Phaeodactylum tricornutum is a diatom. It is the only species in the genus "Phaeodactylum". Unlike other diatoms "P. tricornutum" can exist in different morphotypes (fusiform, triradiate, and oval), and changes in cell shape can be stimulated by environmental conditions. This feature can be used to explore the molecular basis of cell shape control and morphogenesis. Unlike most diatoms "P. tricornutum" can grow in the absence of silicon, and it can survive without making silicified frustules. This provides opportunities for experimental exploration of silicon-based nanofabrication in diatoms.
