Abstract:
The objectives of this research were to identification of period needed each phase in Pyrrosia lanceolata (L.) Farwell fern root cells during mitosis. Pyrrosia lanceolata (L) farwell ferns were obtained from Pekanbaru, Riau. Each phase in mitosis observed by made root cells fresh specimen by squash method. We found that between 3.20 am. Until 3.35 am, overall phase could observe. This result showed that Pyrrosia lanceolata (L._) farwell fern root cells active mitosis at that period or time. Prophase and telophase would be seen at every specimen which obtained from different time. In contrast, it was difficulty get anaphase and metaphase. Therefore, we could not now make some conclusion about period needed each phase in Pyrosia lanceolale (L.) Farwell fern root cells during mitosis.
