Question

Night-blooming flower are generally
A. Lightweight
B. Scented
C. Brightly colored
D. Bloom in clusters

Answer 1

Hint:-Night-blooming flowers mean those flowers which bloom or open during the night time. They mainly white and always bloom in the cluster so they will be visible for pollinating agents. In these flowers, reserves to emit colored pigment are absent. The life span of these flowers is very short.

Complete step-by-step solution:-
The flower that blooms around night time has an exceptionally special test for the Pollination. They have an exceptionally short open window for fruitful pollination by bats and different creepy crawlies. To expand their chances of fruitful pollination, these flowers have normally advanced with specific highlights.
Two of the main highlights are the mellow scent and white-colored blossoms. White gives the best difference among all colors in low light or around evening time conditions. Also, this differentiation can effectively draw in more pollinators for fruitful pollination.
In enormous flowers of the night-time species, pollination essentially happens through bats.
Furthermore, no bats will be pulled into a plant/bloom without nectar or some other food source. So that the soft scent pulls in bugs and moths. The bats come in the exploration for insects and moths and the arising conflict of the bats and creepy crawlies is when pollination happens.
So, the correct answer is B i.e. Scented.

Note:-
They are nocturnal plant species so they mainly attract the nocturnal pollinators and moths while the day plant attracts butterflies and other insects that are active during the daytime.
Flower color is ineffective during the night time. Flower scented attracts the insect for pollination.
Cactus is known as the “Queen of Night-bloom” because its flowers bloom only in the night time around 8 p.m.
