What term describes the plant's ability to tolerate low and high temperatures?

• A. Heat tolerance
• B. Cold hardiness
• C. Drought tolerance
• D. Salt tolerance

Answer: (B)

Temperature tolerance in plants is about surviving environmental stresses from the cold to the heat. Cold hardiness is the term used for a plant’s ability to withstand low temperatures, including freezing conditions. This is why it’s the best fit among the options: heat tolerance covers high temperatures, drought tolerance covers water scarcity, and salt tolerance covers salinity. In practice, cold hardiness helps explain why some plants survive winter cold while others suffer damage; gardeners often relate this to winter hardiness zones.
