have very different fates. They may (1) settle down within the 
wall of the parent cell, and grow out into filaments, which finally 
rupture the parent cell-wall by their elongation ; or (2) they may 
escape, and only after swimming about for a short time settle down 
to grow into filaments; or (3) they may pair first of all, and then

the coupled-cell, after a rest, makes a fresh start of life and growth 
and multiplication within the cell-wall. The life-cycle may be very 
complex. We may even find states in which the cell-walls of the 
filament gelatinise, and the cells themselves round off, the colony 
forming a very irregular mass.
