Definition, Meaning & Synonyms

turgor pressure

noun

/ˈtɜːrɡər ˈprɛʃər/

Definition

The pressure exerted by fluid in a plant cell that pushes the cell membrane against the cell wall, helping to maintain the cell’s shape and structure.

Examples

The turgor pressure in the plant cells allows the stems to stand tall.
Without adequate water, turgor pressure decreases, leading to wilted leaves.
Researchers measured the turgor pressure to study how plants respond to drought conditions.

Meaning

Turgor pressure is essential for the rigidity of plant cells. When the vacuole within the cell fills with water, it causes the cytoplasm to push against the cell wall, creating pressure that keeps the plant upright and reduces wilting.
