Why can frost become a risk for crops in winter?
Answer and explanation
Correct answer: Because near-freezing temperatures can form ice crystals in tender plant cells and damage them
Frost occurs when the temperature reaches near or below freezing. Ice crystals can form in tender leaves, buds and young plant cells, rupturing cells and damaging plant tissue. Therefore, vegetables, fruit crops and other sensitive crops may be harmed. Option B is incorrect because frost does not permanently increase soil nutrients. Exam tip: link frost with damage to tender plant tissues.
