Question

What does the cytoplasm contain?

Answer 1

Cytoplasm refers to the "cell life-substance" that exists outside of the nucleus and encompasses the entire interior of the cell. It performs all of the functions of the cell that the nucleus does not. It's all happening inside the egg, which doesn't have a nucleus.
In $1863$, a Swiss biologist called Rudolf von Kölliker coined the term "cytoplasm," but it was widely used as a synonym for protoplasm. However, the phrase progressively adapted its context to the new meaning of the term "cytoplasm".

Complete answer:
The cytoplasm is the fluid that fills a cell. It was once referred to as fluid protoplasm by scientists. They had no idea there were so many distinct kinds of fluids in the cell at first.
Each cell is completely filled with cytoplasm. A cell membrane surrounds it. Water, salt, and proteins make up the majority of the cytoplasm. All organelles of Eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are found in the cytoplasm.
Special fluid is found in the mitochondria, endoplasmic reticulum, Golgi apparatus, and nucleus. The only 'plasms' left are cytoplasm and nucleoplasm.
The cytoplasm, which is confined within the cell membrane, is a highly viscous fluid. Water, proteins, lipids, nucleic acids, inorganic salts, and polysaccharides make up the majority of it.
The cytoplasm includes organelles as well. The cytoplasm makes up nine-tenths of the entire cell.
The cytoplasm is similarly divided into two layers. These are found in the ectoplasm and endoplasm. Both are commonly used to describe protozoa cytoplasm (particularly amoeba) that varies in form, location, and function.
One of the most important jobs of the cytoplasm is to help cells to maintain their turgidity, which allows them to keep their shape.

Note:
Functions of cytoplasm-
The cytoplasm is a jelly-like fluid that is present inside the cell membrane and includes all of the cell and organelle components. It is made up of salt and water.
Many of the cell's functions take place in the cytoplasm, which contains chemicals and enzymes that are required for waste breakdown.
The cytoplasm also plays a role in metabolic activities.
