Acetabularia: translation
Giant single-celled alga of the Order Dasycycladaceae. The plant is 3-5cm long when mature and consists of rhizoids at the base of a stalk, at the other end of which is a cap that has a shape characteristic of each species. The giant cell has a single nucleus, located at the tip of one of its rhizoids, which can easily be removed by cutting off that rhizoid. Nuclei can also be transplanted from one cell to another.
