a multicellular body with the doubled number of chromosomes growing attached to a sexual generation with the reduced number of chromosomes).
Spores develop free, in direct contact with soil, water and light, whereas the fertilized eggs of archegoniates develop enclosed within cells of the preceding sexual generation.
The first asexual, or neutral, generation differed from subsequent asexual generations because it developed while attached to the preceding female sexual generation.
Therefore, the 'first neutral generation' of Dictyota does not grow attached to a sexual generation.
With respect to archegoniates, Celakovsky considered the asexual generation (sporophyte) to be antithetic to the sexual generation (gametophyte).
