Weight moisture is : water content/ dry weight , if for example it is 4 it means that this plant have for each 1gam of dry mass 4 grams of water. can i use this to interpret the plant use of water ?
If the plant absorbs the water from it surrounding and holding it in its tissues, one can conclude that the plant is using the water because that water is no longer available for use by other plants, animals or non-living matter. It may be difficult to say what the plant is using each molecule of water for since the plant may require it for several cellular processes such as tissue vigor, photosynthesis or homeostatic balance. So, my answer will be yes.
