Protoplasm is the entire content of a cell, and it contains both the nucleus and the cytoplasm. This shows that there is no big difference between cytoplasm and protoplasm. The cytoplasm is not a separate entity; it is part of the protoplasm. Protoplasm and cytoplasm are semi-fluid substances, and each has its own contents. While the protoplasm consists of cytoplasm, cell membrane, and the nucleus, the cytoplasm consists of organelles, vesicles, and cytosol. In other words, cytoplasm refers to the contents of a cell without the nucleus.
The cytosol in the cytoplasm consists of salts, water, and other organic materials, and the organelles in the cytoplasm consist of mitochondria, endoplasmic reticulum, Golgi body, ribosomes, etc. The ribosome is the site for protein synthesis. Protoplasm can be described as the living matter of animal cells. There are different types of processes that occur in the protoplasm, and the functionality of the whole body depends on those processes.
