ULTRASTRUCTRUAL STUDIES ON AXIAL ROW CELL DEVELOPMENT IN ARCHEGONIUM OF NEPHROLEPIS CORDIFOLIA
摘要
Abstract
Development of axial row cells of Nehprolepis cordifolia archegonium was examined with transmission electronic microscopy. Axial row of archegonium consisted of an egg, ventral cell and four neck-- canal cells, the egg being the most important. Nucleus was oval and nucleolus was evident in young eggs. There were abundant organelles in cytoplasm of young eggs. Subsequently, separation cavity and additional membrane formed between egg and adjacent cells. Meanwhile, nucleus changed from elliptical into crescent shape, with nuclear evagination dotted on the rim. Formation of additional membrane and separation cavity, changes in morphology and distribution of nucleus and organelle were all noted. Their functions in development and fertilization of egg were discussed.关键词
