Detailed explanation-1: -Nyctinasty may occur to protect the pollen, keeping pollen dry and intact during the nighttime when most pollinating insects are inactive. Conversely, some flowers that are pollinated by moths or bats exhibit nyctinastic flower opening at night.
Detailed explanation-2: -The flowers of Oxalis open during the day and close at night.
Detailed explanation-3: -The leaves of plants that use C3 photosynthesis absorb sunlight and carbon dioxide during the day, performing photosynthesis while the sun is out.
