Question

cytoplasm = protoplasm - organelle??/then nucleoplasm will also equal to protoplasm - nucleolus (organelle present in nucleoplasm)

Answer 1

Protoplasm is the living content of the cell surrounded by cell membrane which include cytoplasm and nucleoplasm. Therefore, protoplasm= cytoplasm+nucleoplasm. Cytosol is the fluid content of the cytoplasm which exclude the organelles i.e. if organelles and other substances are excluded, the remaining fluid is the cytosol.
