what is the biological term used to describe bloated and rigid plant material?

The biological term used to describe bloated and rigid plant material is turgidity. Turgidity refers to the state of being swollen or distended due to the pressure of water inside plant cells, which presses the cell membrane against the cell wall. This pressure, called turgor pressure, keeps the plant cells firm and rigid and is essential for maintaining the structural integrity and upright posture of plants. Without turgidity, plants would appear wilted and limp. The cell wall, primarily made of cellulose and sometimes lignin, helps the plant cell withstand this pressure and maintain rigidity.
