Question

When the cell walls of the wood is completely saturated but not water exists in the cell cavityies, the wood is said to have reach its ____ ______

Answer 1

Wood is said to have reached its fiber saturation point when its cell walls are fully saturated with water, yet no water is present in the cell cavities, also known as lumens.

Step-by-step explanation:

When the cell walls of the wood are completely saturated but water does not exist in the cell cavities, the wood is said to have reached its fiber saturation point. The fiber saturation point is a key concept in wood science and pathology because it represents the threshold where the cell wall is completely hydrated, and the physical properties of wood are significantly impacted. At this point, the secondary cell walls typically composed of cellulose, hemicellulose, and lignin are fully swollen with water, but the cavities of the cells, or lumens, no longer contain free water.
