Listen to part of a talk in a biology class.
As you probably already know, many animals can regulate their body temperature, even if it's very cold outside. They use what's called thermal regulation to keep their internal body temperature within a comfortable range, but did you know that certain plants used thermal regulation too? Implants disability is beneficial for a couple of reasons. If the weather gets very cold, many plants start to freeze, which damages the structure of their cells, eventually the entire plant might die. But some plants can control their temperature using thermal regulation, so they can prevent this damage. For example, a plant called the skunk cabbage sprouts early in the spring when it's still cold and snowy. While other plants leaves might freeze and their flowers might fall off, the skunk cabbage stays alive in the cold by keeping its leaves and flowers warm. It can even melt near by snow because of the heat it generates. Thermal regulation also helps plants to reproduce, many plants need to attract insects to do this, insects land on the plant and get covered in pollen and carry the pollen to another plant, allowing that plant to be fertilized. Plant thermal regulation helps plants attract insects that will pollinate them, because insects are attracted to warmth. For example, the lotus flower attracts insects by keeping itself warm. The insects actually need warmth to fly. So when it's cold, they seek out the warm lotus plants and land on them. This is good for the lotus flower, because the visiting insects warm up, get covered in pollen and then fly off to other lotus plants.
Using the examples of the skunk cabbage and the lotus flower, explain two benefits of the thermal regulation in plants.

Thermoregulation in plants has two main benefits. First, it helps plants survive in cold weather. For example, the skunk cabbage can keep its leaves and flowers warm even in snowy conditions, preventing them from freezing and dying. Second, thermoregulation aids in reproduction by attracting insects. The lotus flower stays warm, which draws insects that need warmth to fly. These insects land on the flower, get covered in pollen, and then carry it to other flowers, helping the plant reproduce. (95 words)

Thermoregulation offers two key advantages for plants. Firstly, it enables them to withstand freezing temperatures, protecting their cellular structure from damage. The skunk cabbage, for instance, sprouts early in spring when it’s still cold. By generating heat, it keeps its leaves and flowers warm, even melting nearby snow, which ensures its survival. Secondly, thermoregulation facilitates reproduction by attracting pollinators. The lotus flower maintains warmth, which is essential for insects to fly. In cold conditions, insects seek out the warm lotus, land on it, and get covered in pollen. When they fly to other lotus flowers, they enable cross-pollination, aiding the plant’s reproductive success. (100 words)
