I can only take it logically; leaves contain water. Normally, when water is liquid, the hydrogen bonds between the water molecules form and reform. When it freezes, each water molecule bonds with 4 other water molecules and creates a rigid lattice, which holds them together, but further apart than in liquid water.
In a nutshell, water expands when it freezes. So the plants volume will increase suddenly and this can cause the cell walls to bust, causing cell death.
What else can I help you with?
Would you expect a coating of frost to be thicker on the topside or bottom side of a plant leaf on a clear and calm night?
You would expect the frost coating to be thicker on the top side of the leaf. This is because cold air sinks, causing the top side to lose heat and cool more quickly, leading to a more significant frost formation compared to the bottom side of the leaf.
How can a plant easily regrow a damaged stem or leaf?
Plants can easily regrow a damaged stem or leaf through a process called regeneration, facilitated by their ability to produce new cells from meristematic tissue. When a stem or leaf is damaged, the plant activates its meristems to initiate cell division, leading to the growth of new tissues. Additionally, plants often have the capability to redirect nutrients and energy to the damaged area, promoting healing and regrowth. Factors such as water availability, light, and nutrient levels also play significant roles in the plant's regenerative abilities.
