Why can frost damage crops in fields?

Answer and explanation

Correct answer: Because ice crystals can harm delicate plant cells

Frost forms when a surface becomes cold enough for water vapour to change into ice, or for deposited water to freeze. Ice crystals on a plant can injure delicate leaves, stems, flowers, and especially living cells containing water. Freezing may damage cell membranes and tissues, causing wilting, browning, or reduced growth. This is why a frost event can be harmful to crops even when the ice layer looks thin.

Option D is correct because it identifies the direct biological effect of ice crystals on soft plant tissues. Frost does not turn soil into gold, empty the air, or increase sunlight. The actual damage depends on temperature, duration of cold, crop type, and the plant’s stage of growth, but the central reason is freezing injury to sensitive cells.
