Question

Why some organism's have two nucleus

Answer 1

Yes, they are called multi nucleate.There are two types of multinucleated cells

• Syncytia
• Coenocytes

• Coenocyte: when a single cell with a single nucleus performs several cell divisions without dividing the cytoplasm (cytokinesis);
• Syncytium: when several uninucleate cells aggregate, forming a single multinucleate cell.

Therefore, every syncytium is a multinucleate cell, but not every multinucleate cell is a syncytium.
