These structures are classified as alete if their surfaces lack laesura or ridge lines. Buildup of Buller’s drops accompanies the release of these structures in a “surface tension catapult” mechanism. These structures are concentrated in strobili by Equisetum. Blastic and thallic processes produce a non-motile type of these (10[1])structures called conidia. (-5[2])Columella support “vessels” (10[1])enclosing these structures, which are singular and unbranched (-5[1])in bryophytes. (10[1]-5[1])A haploid (-5[1])gametophyte (-5[1])phase (-5[2])contrasts with a diploid (10[1])phase (10[1])that produces (-5[1])these (10[2])structures (10[8]-5[1])in alternation (10[1]-5[2])of generations. (10[5]-5[2])Puffballs (-5[1])have fruiting (10[1])bodies (10[1]-5[2])that (10[1])burst (10[3])to release (10[3])these (10[1])structures, (10[7]-5[5])which are formed (-5[1])in gills (10[3])beneath (-5[1])the cap. (10[1])For 10 points, (10[1])name these reproductive structures (10[1])that, (10[1])unlike seeds, are dispersed (10[1])as (10[1])unicellular units. (10[2])■END■ (10[24]0[3])
