What is the meaning of protoplasm?

Dear student,
Please find below the answer:

The cytoplasm along with the cellular organelles is called protoplasm.
Protoplasm = Cytoplasm + Organelles or Protoplasm - Organelles = Cytoplasm.

Or we can say,

The term protoplasm includes both the substance within the cell and the cell membrane. 

Hope this clears your doubt.
Regards.
