Watch out for colonial protists, though, such as Volvox, which forms a spinning ball of green cells. More complex organisms such as jellyfish, coral, and sea anemones have a tissue level of organization. Do you want to delete this option? This is called binary fission. All of the cells in a multicellular animal are still descended from a single cell, however, and that cell is the product of a sperm meeting an egg from a previous generation. In this, a single cell divides, giving rise to two daughter cells. Therefore, this correspondence argues and requests recommendation committee on cell death to revisit the nomenclature of cell death processes in the unicellular organisms. In this Special Feature, we look at the existing evidence against and in support of the idea that menstrual cycles synchronize with lunar cycles.
