description Mermaid's Wineglass (Acetabularia acetabulum) Overview

Mermaid's Wineglass (Acetabularia acetabulum) is a species of green alga found in subtropical waters, including the Mediterranean Sea. It is a single-celled organism that can grow up to 10 centimeters tall, featuring a distinctive umbrella-like cap that resembles a wineglass. The species is scientifically significant because Joachim Hämmerling used it in the 1930s to demonstrate that the cell nucleus controls cellular development and morphology.

help Mermaid's Wineglass (Acetabularia acetabulum) FAQ

Is Mermaid's Wineglass really just one single cell?

Yes, despite being able to grow up to 10 centimeters tall, *Acetabularia acetabulum* is a single-celled green alga. Its large size makes it a classic model organism in biology for studying cellular structure and regeneration.

Where is the best place to find Mermaid's Wineglass in the wild?

You can find this species of green alga in shallow, subtropical waters, particularly in the Mediterranean Sea. They often attach themselves to rocks or coral rubble in clear, warm water.

How does a single cell grow into the shape of a wineglass?

The organism features a distinctive umbrella-like cap that resembles a wineglass, which is formed by radiating rays. The single cell's nucleus remains at the bottom of its stalk while it grows this complex top structure.

Are there any famous biological experiments involving Mermaid's Wineglass?

Yes, it was central to the experiments of Danish biologist Joachim Hämmerling in the 1930s and 1940s. He transplanted parts of the algae to prove that the nucleus controls the cell's form and heredity.
