"Padina pavonica
The life cycle of this seaweed includes sexual reproduction and spore-producing asexual reproduction. In Britain the fronds die back in winter and the rhizoids resprout in the early summer, producing new fronds. After about twenty days these are mature, 20 mm (0.8 in) long or more, and produce tetraspores in concentric rings a millimetre or so wide. By the time the frond reaches a length of 50 mm (2.0 in) it will have produced six to twelve generations of tetraspores. In Britain, plants seem to reproduce entirely asexually but in other parts of the seaweed's range, plants can be either male or female and produce gametophytes which release gametes into the sea..
