<human>:  How do plants respond to changing temperatures?
<bot>: Plants typically respond to changing temperatures by adjusting the rate of photosynthesis, the process by which they convert sunlight into energy. Additionally, they may alter the composition of their leaves, flowers, and other structures in order to better tolerate extreme temperatures. Depending on the species, some plants may become dormant in order to better survive cold winter temperatures, while other plants may shed their leaves in order to conserve moisture during hot summer temperatures.
