Water's high specific heat lets it absorb/release large heat quantities with little temperature change, buffering biological systems; a root hair cell contains a nucleus, mitochondria and a prominent vacuole for water uptake.
(a) Water has an unusually high specific heat capacity compared to most other common liquids, meaning a relatively large amount of heat energy must be absorbed to raise its temperature (or released to lower it) by a given amount. Because living tissues and cells are largely composed of water, this property allows organisms - and bodies of water in the environment - to resist rapid or drastic changes in temperature even when they gain or lose considerable heat, effectively acting as a thermal buffer that keeps internal (and local environmental) temperatures relatively stable. …
