Fertilizers are often applied to lawns without considering osmosis. Why should grass always be watered when applying fertilizer? A. The fertilizer would create a hypotonic environment, causing the grass to swell with water and die. The water is added to wash all the fertilizer away so it does
not burst the plant cells.
B. This is just a superstition. It is not related to osmosis.
C. The fertilizer would create a hypertonic environment, causing the grass to dehydrate and die. Adding water would dilute the fertilizer and lessen the effect.
D. Fertilizer is toxic and kills the grass. Osmosis does not play a role.
