Why can frost be more damaging to crops than dew?

Answer and explanation

Correct answer: Because ice crystals can damage tender plant cells

Correct answer: D. Dew is liquid water deposited on a surface when the surface cools but remains above freezing. Frost forms under freezing conditions, so ice crystals can develop on or within contact with plant tissues. These crystals may injure delicate leaves, buds, and other tender cells by physically damaging cell structures and contributing to freezing stress. A is wrong because frost does not always warm soil; it is associated with freezing conditions. B is wrong because frost requires moisture, even if the air is not visibly wet. C is wrong because the principal agricultural danger is freezing injury, not an immediate increase in evaporation. The memory cue is: dew wets plants, while frost freezes and can injure them.
