Answer 1
Not all of them close -- "night-blooming jasmine" for example. They close at night because of the light and the temperature changes
Answer 2
Saying that flowers close at night because of light and temperature changes is in effect saying they close at night because it is night. It is not an explanation because if it didn't benefit them flowers would have evolved ways to stay open. What is needed is an explanation of the advantages it gives the flower to use up extra energy closing at night then opening in the day. The probable reason is that the dew at night and early morning prevents the pollen from being spread, the low temperatures at night harm the pollen, the moths and other night life do more harm than good to the pollen and so on.
