Overall solute concentrations higher on the outside than on the inside of cells; relatively speaking, concentrated.
Contrast hypotonic and isotonic solutions. See also osmosis.
The following video shows nice experiments using dialysis tubing indicating the impact of osmosis on cell volume:
The following video is really nicely done, save for some math issues, using chicken eggs with dissolved shell as shrinking and expanding cells:
The following video nicely shows contraction of the cytoplasm of onion cells while in a hypertonic solution:
