1. Comparing osmosis

2. Plants
Plant cells are surrounded by rigid cellulose walls, (unlike animal cells), but plant cells still take in water by osmosis when placed in pure water. However, plant cells do not burst because their cellulose cell walls limit how much water can move in. The cell walls exert pressure, called turgor pressure, as the cells take up water. Turgor pressure is analogous to the air pressure of an inflated tire. 

4. Animals
If red blood cells are placed in a solution with lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell and eventually burst (hemolysis); such a solution is hypotonic to the cells, while cell cytosol is hypertonic to the plasma.

6. Paramecium
Paramecium doesn’t explode because it lives in hypotonic pond water that constantly enters cell, but is offset by osmoregulation.
