At what temperature do plants freeze, and how does this affect their growth and survival?

Plants freeze at temperatures below 32 degrees Fahrenheit (0 degrees Celsius). When plants freeze, the water inside their cells turns into ice crystals, causing the cells to burst and damaging the plant's tissues. This can lead to wilting, browning, and ultimately death of the plant. Additionally, freezing temperatures can disrupt the plant's ability to take up water and nutrients from the soil, further impacting its growth and survival.
