Мне казалось логичным спросить на микроскопном форуме, где вроде как куча профессионально разбирающихся в микроорганизмах людей которым не "впадлу" (c) ответить. Видимо обсуждение произношения слова Nikon сейчас актуальнее.
Для галочки:

Цитата:
Lotsy conjectured that the dancing crystals of gypsum in vacuoles of Closterium and several other genera of Des-midiaceae act as statoliths, but Fischer stated that they do not sink against the lower side of the vacuole, being kept in its center by rapid protoplasmic streaming. If the stage of the microscope is placed vertically, however, the crystals are seen to sink immediately to the lower surface of the vacuole. This was observed without exception in many species of Closterium. The motion of C. leibleinii was investigated by vital staining. When a cell is about to turn over, cytoplasm accumulates in the upper end, and by its weight tips the cell. If the descending end touches the substratum, it is attached by mucilage, secreted probably in response to a stimulus from the crystals, which collect at the polar end of the vacuole. The other end of the cell points upward as long as the bulk of the bulk of the cytoplasm remains in the lower tip. The crystals are statoliths and the terminal vacuole a kind of stato-cyst.
