¶¶Difference between Cytoplasm and Protoplasm are following :

1)Cytoplasm is a part of protoplasm.

2)Protoplasm includes the nucleus, whereas cytoplasm does not.

3)Cytoplasm consists of organelles except the nucleus, whereas protoplasm consists of nucleus, cytoplasm, and plasma membrane.

4)Unlike the cytoplasm, protoplasm is considered as the physical basis of life.

The difference Between Cytoplasm and Protoplasm are almost minimal and both terms are used interchangeably. But for academic purposes, Cytoplasm is all the contents inside the cell membrane excluding the nucleus. And protoplasm includes cytoplasm, plus, the nucleus of the cell.

What is Cytoplasm?

The Difference Between Cytoplasm and Protoplasm are confusing because the meaning they convey are often interchanged. It is now known that the “cell” comprises of many organelles (Ribosomes, Endoplasmic reticulum etc) which perform specific functions. These cells organelles are engulfed in a gel like substance called Cytosol. This is collectively known as cytoplasm. But it doesn’t include the nucleus.


And Protoplasm?

A protoplasm on the other hand, includes the cytoplasm + the nucleus. Therefore, cytoplasm is part of the protoplasm. The other thing to note is that the term “Protoplasm” is no longer technically used and is considered obsolete in modern biology. The term was used in the 1800s and described a number of things over the course of a century. The term is now mostly accepted a general term for cytoplasm.

Difference Between Cytoplasm and Protoplasm

Cytoplasm makes up about 70% of the contents of the cell. It’s made up of structural filaments, and water. Protoplasm consists of cytoplasm, the nucleus and the nucleoplasm. So essentially, protoplasm consists of all the organelles suspended in the cytosol, along with the nucleus. The two major differences between Cytoplasm and Protoplasm are summarized below:

Conclusion

The difference Between Cytoplasm and Protoplasm are almost minimal and both terms are used interchangeably. But for academic purposes, Cytoplasm is all the contents inside the cell membrane excluding the nucleus. And protoplasm includes cytoplasm, plus, the nucleus of the cell.
