摘要:

AbstractAn unusually persistent ventral canal cell has been observed in a few archegonia ofPhyscomitrium cyathicarpumMitt. Ultrastructural investigations revealed a close similarity between the ventral canal cell and the egg. The similarity in fine structure of these cells provides support for the idea that the ventral canal cell is an abortive egg.
