Question

Acetabularia used in Hammerling's nucleocytoplasmic experiments is

• A. Unicellular fungus
• B. Multicellular fungus
• C. Unicellular uninucleate green alga
• D. Unicellular multinucleate green alga

Answer 1

The correct option is C Unicellular uninucleate green alga

• Acetabularia is a genus unicellular or single-celled green algae belonging to the family Polyphysaceae which are found in subtropical waters.
  

• They are gigantic in size and complex in form, therefore, used in experiments in cell biology.
• Hammerling's nucleocytoplasmic experiments state that the cytoplasm is the centre for all the metabolic activities in the cell and the nucleus is the controlling centre.
  
• So, the correct answer is 'Unicellular uninucleate green alga'.
