Turgidity and Flaccidity
Turgidity and flaccidity are terms used to describe the ability of a plant to expand and contract in response to changes in water potential. These terms are essential for understanding how plants absorb water from the soil.
Turgidity is the ability of a plant to expand and absorb more water. It is determined by several factors, including the plant's cell size, shape, and the presence of specialized tissues called xylem vessels.
Flaccidity is the ability of a plant to contract and release water. It is determined by the plant's cell wall composition and the presence of pores called root hairs.
Examples
Turgidity: The stem of a sunflower is turgid and can expand significantly when it absorbs water.
Flaccidity: The roots of a cactus are flaccid and contract when they absorb water.
Turgidity and Flaccidity: The leaves of a plant can be both turgid and flaccid, depending on the water conditions
