Here's why:
* Photosynthesis: Night-blooming flowers, like all plants, perform photosynthesis to create their own food. This process uses sunlight to convert carbon dioxide and water into sugars for energy.
* Stored energy: While they may bloom at night, they still need to photosynthesize during the day to store enough energy to fuel their blooming and other processes during the night.
The difference: Night-blooming flowers have adapted to use the moon and stars for pollination, as their target pollinators are active at night. They don't need sunlight to bloom, but they still rely on it for their basic survival.
