Summary Introduction
Concept Introduction: Choanoflagellates are flagellated cell in which the flagellum is surrounded by a collar of threadlike projections. Mostly the choanoflagellates live as single cells but in some organisms they form colonies. These colonies are formed by mitosis, when the descendant cells do not separate after the division. The cells consist of adhesion proteins and they will help them to stick together.
