Valonia ventricosa
Valonia ventricosa, also known as bubble algae, sea grape, or sailor's eyeballs, is a species of algae found in oceans throughout the world in tropical and subtropical regions, within the phylum Chlorophyta. It is one of the largest known unicellular organisms. Characteristics Valonia ventricosa has a coenocytic structure with multiple nuclei and chloroplasts. This organism possesses a large central vacuole that is multilobular in structure (lobules radiating from a central spheroid region). The entire cell contains several cytoplasmic domains, with each domain having a nucleus and a few chloroplasts. Cytoplasmic domains are interconnected by cytoplasmic "bridges" that are supported by microtubules. The peripheral cytoplasm (whose membrane is overlaid by the cell wall) is only about 40 nm thick. Valonia ventricosa typically grow individually...
