| After 8 to 9 weeks, archegonia had developed on the lower surface of the gametophytes just behind the growing apex. |
| The tetraspores and the gametophytes are the only haploid stages in the coralline algae. |
| Those gametophytes consisted of short, curved uniseriate filaments of 2-3 cells, some bearing antheridia. |
| To expose gametophytes to particular photoperiodic conditions, the bagged Petri plates were placed in a light-tight box over which was installed the fluorescent source. |
| Furthermore, logs provide persistent, exposed substrate where thalloid gametophytes can escape smothering by deciduous hardwood leaf litter. |
| A stereomicroscope and a compound light microscope were used to work out the density and to examine the morphology, sizes and genders of the gametophytes. |
