To examine the ancestral character states of growth types in unicellular or multicellular organisms, coding schemes represented varying levels of complexity and hypotheses regarding the homology of growth types. The shown color-coded character state distributions represent yellow for unicellular growth and purple for multicellular growthsensu lato(including sarcinoid, filamentous, and parenchymatous growth). Note ancestor nodes for (1) Klebsormidiophyceae and Phragmoplastophyta 1008.4 million years ago (mya) and (2) Klebsormidiophyceae 830.8 mya.
