Difference between cytoplasm and nucleoplasm and protoplasm

Dear student 
The cytoplasm or cytosol is the gel like material that is enclosed in a cell membrane.
Nucleoplasm(contain nucleotides, enzymes etc) is also like cytoplasm but it is present inside the nucleus and enclosed by a nuclear membrane.
protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm.
So protoplasm consist of both Nucleoplasm and cytoplasm.
