Paul, 1. Read about “coalescence” and combine this with the existence of sex-like mechanisms in unicells.
Yet another reason Paul Nelson is extremely silly - The Panda's Thumb 2007

Well, on page 155 they write: “This reduction in predation pressure allowed the Chlorella population to recover and increase rapidly, …During the recovery of the algal population, an unexpected result was observed: the prey Chlorella now included colonial growth forms as well as unicells 10 days.”
-
Another reason may be that unicells are simply not recognized as Scenedesmus.
-
So the unicells are grazed down for the first five days, and then in the next five days, ‘colonies’ appear.

Trainor 1979 observed that unicells disappeared when incubated in dialysis sacks in the field or when cultured in pond water in the laboratory.
-
So, in the paper at hand, if the ‘chemical inducer’ began to be produced after 3 days, then on the 5-day mark, the unicells would begin to react.
-
Therefore, since the unicells were present at .1% of their initial levels, we would expect the cast-off walls to be present at a similarly reduced rate.

In fact, in culture unicells may be very common e.g.
-
One explanation could be that due to the activity of grazers unicells are produced only in very low numbers, which experience a high mortality ; protective colonies are being induced.
