Verified step by step guidance

Begin by understanding the concept of pressure within cells. Pressure in biological contexts often refers to the force exerted by fluids or gases within or outside of cells.

Identify the role of the cytoplasm in a cell. The cytoplasm is the gel-like substance within the cell membrane that contains all organelles and cell parts.

Consider the effect of the cytoplasm on the cell membrane. The cytoplasm can exert pressure on the cell membrane, especially when the cell is full of water.

Learn about turgor pressure. Turgor pressure is the force exerted by the fluid (cytoplasm) inside the cell against the cell membrane, which is crucial for maintaining the cell's shape and rigidity.

Differentiate turgor pressure from other types of pressure. Atmospheric pressure is the pressure exerted by the weight of the atmosphere, osmotic pressure is related to the movement of water across membranes due to solute concentration differences, and hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to gravity.
