The reults for the macroscopic part:
0.30M glycerin – solution was translucent (could see text behind the test tube)
0.15M NaCl – solution was opaque (could not see text behind the test tube)
0.30M NaCl – solution was opaque (could not see text behind the test tube)
0.15M glucose – solution was translucent (could see text behind the test tube)
0.30M glucose – solution was opaque (could not see text behind the test tube)
0.30M Urea – solution was translucent (could see text behind the test tube)
Results for microscopic part:
0.30M glycerin – no cells present
0.15M NaCl – normal sized cells
0.30M NaCl – crenated (shrunken and star-shaped) cells
0.15M glucose – no cells present
0.30M glucose – normal sized cells
0.30M Urea – no cells present
