Animal calls have membranes that are referred to as "semi-permeable." The cell will not take on water unless it needs to essentially - a condition regulated by the cell resulting in solute concentration changes in the cytoplasm. Movement of even the tiniest gas molecules often requires an energy utilizing process - - these are sort of grouped together as "active transport," and the movement in or out of the cell that does not require energy - these referred to as "passive transport." The rub is that there are many many specific ways that this may happen. So your question regarding animal cells really becomes one that takes into consideration renal function- and the homeostatic processes that regulate serum ion concentration of 1) sodium, 2) proteins. When depleted in the serum - Na and proteins - the vascular compartment will take on water from the interstitial compartment, and this will eventually effect the inner cellular environment - but that is the last "compartment" to change - again because of the specific structure and various specific macro-molecules embedded in...the cell membrane. Plants have a similar situation - but the maintenance of the extracellular solute concentration is far less regulated - less complicated - in other words plants don't have kidneys - but we are talking about the processes whereby water moves in or out of cells - and this is a feature of a) the cell membrane b) the solute concentration and balance of both intracellular and extracellular environments - which again, can be screwed up more easily in a plant. By implication - there would be potentially more "wrong" physiologically in the case of an animal cell gaining more water than it needs - and the above discussion should give some indications why - more wrong that is than in the case of plant physiology - but the "which is worse" part of that question is somewhat non-sequitur since these are processes that occur in response to changes - and the changing of the biochemistry that results in a eukaryotic cell from any kind of organism "gaining water" could be as "proper" as "improper" given circumstances - if you mean which cell can tolerate the more drastic changes in water gain or loss - again - this is mediated more by extracellular conditions than intracellular so that is sort of hypothetical.
