Verified by Toppr

In thallophytes, the female sex organ is a single-celled oogonium. It is not covered by any sterile jacket layer. In Bryophytes, the female sex organ is flask-shaped, multicellular archegonium which remains covered by a sterile jacket layer. Neck canal cells, ventral canal cell and egg are found within archegonium.
