The question is incomplete. There are no options given (for "which of the following") to answer this question.
Cells are surrounded by a cell membrane, also known as the plasma membrane. This thin, semi-permeable barrier separates the contents of the cell from its external environment while controlling the passage of substances in and out of the cell.
The plasma membrane separates the interior of all cells from their external environment. It is a selectively permeable barrier that controls the passage of substances in and out of the cell.
Cytokinesis is the cell process following meiosis or mitosis where the cytoplasm divides and separates into new daughter cells. This ensures that each new cell has its own set of organelles and a complete copy of the genetic material.
Both eukaryotic and prokaryotic cells contain genetic material in the form of DNA, a cell membrane that separates the cell from its environment, and ribosomes that are responsible for protein synthesis. Additionally, both types of cells have cytoplasm where various cellular processes take place.
If it were not for the cell membrane serving as a selectively permeable barrier, the cell's contents would equilibrate with its surroundings due to diffusion. This membrane controls the movement of substances in and out of the cell, allowing it to maintain its internal environment and carry out essential cellular functions.

what separates prokaryotic and eukaryotic cells from the watery environment in which they exists
Cell contents are separated from the external environment by the cell membrane. Cells are also separated by the external environment when they are in the bloodstream in the capillaries and veins.
Cells are surrounded by a cell membrane, also known as the plasma membrane. This thin, semi-permeable barrier separates the contents of the cell from its external environment while controlling the passage of substances in and out of the cell.
The Cell Membrane forms the outside boundary that separates the cell from its environment.
Selective permeability
Yes, the plasma membrane acts as a semi-permeable barrier that separates the contents inside the cell from its external environment. It regulates the passage of molecules in and out of the cell to maintain internal balance and protect the cell from potentially harmful substances.
The cell membrane is the outer boundary of a plant cell that separates its contents from the surrounding environment. Within the cell, membrane-bound organelles such as the nucleus, vacuole, and chloroplasts also help compartmentalize and protect the cell's contents. The cell wall, which is found outside the cell membrane in plant cells, provides additional structural support and protection.
In cells without a cell wall, the outside boundary that separates the cell from its environment is formed by the cell membrane or plasma membrane. This phospholipid bilayer regulates the passage of molecules in and out of the cell, allowing for selective permeability.
In cells without cell walls, the cell membrane forms an outside boundary that separates the cell from its environment!
