- meiosis is cell division resulting in the reduction of a chromosome number in half.

puteri [66]

The things with winter and overnight freeze are that this change of the weather can seriously harm the crop and do irreversible damage.

To prevent this, farmers use some methods.

One is the usage of heaters, not allowing the freeze to set.

Another one is to spray the crop with water before the predicted overnight freeze. When water freezes and turns into ice, it releases latent heat. Then, the ice that builds upon the plant will insulate it from the colder surrounding air temperatures.
