What is the term for the pressure within a plant cell?

The term that refers to the pressure within a plant cell is turgor. Turgor pressure occurs when the vacuole of a plant cell fills with water and exerts outward pressure against the cell wall. This is vital for maintaining cell structure and rigidity, enabling plants to stand upright and preventing wilting. Turgor pressure is created by the osmotic movement of water into the cell, but it specifically denotes the pressure that results from this process.

Osmosis is related but refers to the movement of water across a semipermeable membrane and does not directly describe the internal pressure. Humidity pertains to the moisture level in the environment and does not apply specifically to cell pressure. Photosynthesis is the process by which plants convert light energy into chemical energy, which is a separate function unrelated to cell pressure mechanics. Turgor is essential for plant health, growth, and overall function, making it a crucial concept in understanding plant biology.
