Question

Объясните почему тепловые растения гибнут После первых заморозков​

Answer 1

Ответ:

Растения, перенесшие в зимний период температуру – 30°С, могут погибнуть весной при небольших заморозках.

Answer 2

Why do heat-loving plants die after the first frost?

Heat-loving plants, also known as thermophilic plants, are adapted to thrive in warm temperatures and are sensitive to cold temperatures. When exposed to frost, these plants can suffer damage or even die. There are several reasons why heat-loving plants may not survive after the first frost:

1. Cellular damage: Frost causes ice crystals to form within plant cells, leading to cellular damage. Ice crystals can rupture cell membranes and disrupt the flow of nutrients and water within the plant.

2. Dehydration: Frost can cause water to freeze within the plant's tissues, leading to dehydration. As the water freezes, it expands and can rupture cell walls, causing further damage.

3. Disruption of metabolic processes: Cold temperatures can slow down or halt metabolic processes within the plant. This can affect the plant's ability to photosynthesize, absorb nutrients, and carry out other essential functions.

4. Damage to plant structures: Frost can cause physical damage to the plant's structures, such as leaves, stems, and roots. This damage can weaken the plant and make it more susceptible to disease and other stressors.

5. Lack of cold tolerance: Heat-loving plants are not adapted to withstand cold temperatures. They may lack the physiological mechanisms, such as antifreeze proteins or protective compounds, that allow other plants to survive freezing temperatures.

It's important to note that not all heat-loving plants will die after the first frost. Some may be more cold-tolerant than others and can survive mild frosts with minimal damage. Additionally, certain gardening practices, such as providing protective coverings or moving potted plants indoors, can help mitigate the effects of frost on heat-loving plants.

Conclusion

Heat-loving plants are not adapted to withstand cold temperatures, and exposure to frost can cause cellular damage, dehydration, disruption of metabolic processes, and physical damage to plant structures. These factors contribute to the death of heat-loving plants after the first frost. However, it's worth noting that some heat-loving plants may be more cold-tolerant than others and can survive mild frosts with minimal damage.
