1. Cytoplasm: This is the gel-like substance that fills the space between the cell membrane and the nucleus. It is primarily composed of water, but also contains dissolved salts, sugars, proteins, lipids, and other molecules essential for cellular function.
2. Nucleoplasm: This is the fluid inside the nucleus of the cell. It contains the cell's genetic material, DNA, as well as proteins involved in DNA replication and transcription.
It's important to note that these fluids are not completely distinct. They are connected through the nuclear pores, which allow for the passage of molecules between the nucleus and cytoplasm.
