Acetabularia is a genus of green algae in the family Polyphysaceae. [4] Typically found in subtropical waters, Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology . [ 5 ]
Life cycle of Acetabularia acetabulum. This alga adheres to the substrate with rhizoids (root-like processes), and these are the only part of the alga present in the winter. . The thallus consists of a single cell, and in the spring a slender stem develops from the holdfast, growing vertically to a length of about 5 cm (2 i
Acetabularia caliculus, the umbrella alga, is a species of green alga found in shallow temperate and tropical seas. It usually grows on pebbles, shells or pieces of rock, and is often found in seagrass meadows , on mudflats and coral reefs , in estuaries and growing on the submerged roots of mangroves .
Acetabularia crenulata, one of the many species known as mermaid's wineglass, is a form of green alga generally found in shallow tropical seas. It can be found growing in great abundance along stretches of the overseas highway to Key West, Florida bordering on Florida Bay .
Hämmerling began growing Acetabularia in laboratories in the 1930s. [2] [3] There he discovered that the plant had one cell and the nucleus was always located in the rhizoid. [3] Then he began studying the roles of the nucleus and cytoplasm by experimenting with the Acetabularia. [4]
There are three bones of the os coxae (hip bone) that come together to form the acetabulum.Contributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum.
The thallus of the unicellular mermaid's wineglass, Acetabularia, can grow to several inches (perhaps 0.1 to 0.2 m) in length. The fronds of the similarly unicellular, and invasive Caulerpa taxifolia can grow up to a foot (0.3 m) long. [citation needed]
