Why is dew generally not considered as damaging to crops as frost?

Correct answer: Dew is liquid water, whereas frost can form ice crystals that damage tissues

Direct answer: A. Dew is liquid water that condenses on a cool plant surface. In ordinary conditions it does not freeze into sharp ice crystals inside or around delicate plant tissues. Frost forms when water vapour deposits as ice or when water freezes during sufficiently cold conditions. Ice formation can injure plant cells because it may draw liquid water away from cells and physically disrupt delicate tissues. Therefore frost is commonly more damaging than dew, although the actual effect depends on plant type, temperature, duration, and exposure. A is correct because it identifies the important physical difference: liquid droplets versus ice. B is false because dew is water. C is false because frost is associated with freezing conditions and does not warm plants. D is false because dew does not cut roots. Memory cue: dew is wet; frost is frozen—crop injury is mainly linked with freezing.
