<human>:  How do tropical plants survive cold temperatures?
<bot>: Tropical plants have a variety of ways to survive cold temperatures. One method is to enter a state of dormancy, where they suspend their growth and enter a hibernation-like state until the temperatures rise again. They may also have structural adaptations, such as thicker leaves, that help to protect them from frosty air. They may also use sugars and chemicals, such as antifreeze proteins, to trap heat and prevent their cells from forming ice crystals. Lastly, some plants may have the ability to move towards warmer climates in order to survive cold temperatures.
