BIO NMDCAT Biological Importance of Water
nmdcat.online June 27, 2026

The phenomenon of turgor pressure in plant cells is a direct result of

A. The active transport of water into the cell vacuole
B. The osmotic influx of water into a cell enclosed by a rigid cell wall
✓
C. The evaporation of water from the surface of the leaf
D. The adhesion of water molecules to the cellulose cell wall

📝 Explanation

When a plant cell is in a hypotonic environment, water enters by osmosis, causing the protoplast to swell and press against the rigid cell wall. This hydrostatic pressure, called turgor pressure, provides structural support to non-woody plants.
