Why is frost considered more dangerous for crops than dew?

Answer and explanation

Correct answer: Because ice crystals can damage plant cells (क्योंकि बर्फ के क्रिस्टल पौधों की कोशिकाओं को नुकसान पहुंचा सकते हैं)

Correct answer: A. Dew is liquid water deposited on a plant, whereas frost involves freezing conditions and the formation of ice crystals. Ice may form on or within plant tissues, and freezing can injure cell membranes and other delicate structures. This is why frost can cause agricultural damage, especially to sensitive crops, although the severity depends on the crop and the duration and intensity of the cold. B is wrong because dew is water in liquid form. C is wrong because frost is associated with freezing, not heat. D is wrong because ordinary dew does not burn plant roots. The key comparison is liquid moisture versus freezing moisture. Memory cue: dew wets plants; frost freezes and injures them.
