Most of the desert plants bloom during night time because
- controlled by low temperature
- sensitive to moon phases
- insects eat flowers during day
- desert insects are active during night
Explanation
Option (d) is correct
- Most desert plants bloom at night to align with nocturnal pollinators and to reduce heat stress and water loss during the day. Since many desert pollinators—such as insects and bats—are active at night to avoid extreme daytime temperatures, flowering at night enhances pollination and reproductive success. Features like pale flowers, strong fragrance, and nectar production further support night-time pollination in arid environments.
