From: Quantitative analysis of cell-type specific gene expression in the green alga Volvox carteri
Phenotype of Volvox carteri and appearance of separated cell types. A) Wild-type phenotype of an asexual female of Volvox carteri f. nagariensis containing ~2000 small, terminally differentiated somatic cells at the surface and ~16 large reproductive cells (gonidia) in the interior. More than 95% of the volume of such a spheroid consists of a complex but transparent extracellular matrix. B) Isolated somatic cell sheets of V. carteri. C) Isolated gonidia of V. carteri.
