I have not heard of the term capillary water, but I suppose the intercellular spaces may contain water, as plant cell walls are not all impermeable to water. This usually only applies to specialised cell types that have walls specificially made to retain/exclude water, usually by incorporation of lignin, cutin or suberin.

Hi Terry, Thank you for your consistent sharing. I just want to know about the difference of intracellular and intercellular water. About 90% water exist in fruits and vegetables is intercellular water. However, all of the water present is plant cell is trapped by cell wall. Therefore, is there any physicochemical differences between these intracellular and intercellular water.

Thanks again for your time.

I'm not sure I can provide the answer, perhaps tagging your question as plant biology, plant physiology or even botany may get you some better answers.
