Final answer:
When the sun has risen with a burning heat, it can cause plants to wither or wilt due to water loss and dehydration.
Step-by-step explanation:
When the sun has risen with a burning heat, it can wither plants. This process is called wilting.
When the sun's heat is too intense and the plant loses more water through evaporation than it can absorb from the soil, the plant can become dehydrated and its cells can shrink, causing the leaves and stems to droop or curl. This is a defense mechanism that helps plants conserve water during times of extreme heat and drought.
For example, sunflowers, which are known for their ability to tolerate heat, will orient their heads eastward to minimize exposure to the afternoon sun. They also have adaptations, such as deep root systems and thick leaves, that help them retain water and survive in hot conditions.
However, even sunflowers can experience wilting if the heat and drought are too severe.
In summary, when the sun has risen with a burning heat, it can cause plants to wither or wilt due to water loss and dehydration. This is a natural response to extreme heat and helps plants conserve water during periods of high temperature and low moisture.
