How the growth of a giant single cell is intertwined with daily self-rhythms

Caulerpa is a type of marine algae made up of one extended cell, though each plant can grow to be a meter across. While there are many individual nuclei within a Caulerpa plant, it contains no cell membranes that would normally divide the plant into many individual cells, resulting in a free-floating environment of cytoplasmic goo. As a result, Caulerpa poses interesting questions for developmental biologists—how does it carry out the normal functions of plants without being made up of separate cells?
