Throughout evolution, living things have repeatedly developed physically distinct sexes, but how does this actually happen? A discovery in the multicellular green alga, Volvox carteri, has revealed ...

The membrane structural lipids of somatic cells and gonidia isolated from Volvox carteri f. nagariensis spheroids have been characterized. The principal polar lipid components of both cell types are ...

Cell division ensures growth or renewal and is thus vital for all organisms. However, the process differs somewhat in animals, bacteria, fungi, plants, and algae. Until now, little was known about how ...

One of the most pivotal steps in evolution -- the transition from unicellular to multicellular organisms -- may not have required as much retooling as commonly believed, scientists have found. A ...

IN this third memoir M. Janet approaches the problem of the ontogenesis of the Volvox blastea (ccenobium). He confines himself to the methods of cell bipartition, but in later works he proposes to ...
