Mitochondria and Golgi bodies are not present in Spirogyra cells. Spirogyra cells consist of two parts, the cell wall and the protoplast. The protoplast is differentiated into plasma membrane, cytoplast, nucleus, one or more chloroplasts with pyrenoids and a large central vacuole.

Mitochondria are minute bodies occuring often in very large numbers, in the form of short rods or long filaments or as somewhat spherical or oval bodies in the cytoplasm of all plant and animal cells with the exception of bacteria and blue-green algae. Golgi bodies appear as minute net-like structures found only in certain types of cells, and are more common in animals than in plants.
