Compare the cold resistance of herbaceous plants.

Some plants are able to survive the cold, and some are forced to shed their leaves before the onset of cold weather. Temperatures below zero Celsius cause water to crystallize. Water crystals destroy cellular structures and tissues die. This applies to most deciduous plants. But some plants are evergreen. This is due to the presence of special substances that prevent water from freezing and destroying the cell. These substances are a kind of antifreeze for plant cells.
