A red flower viewed by green light will appear to be black.
If a plant is kept under green light for an extended period, its photosynthesis will be affected as green light is not efficiently absorbed by chlorophyll, the pigment responsible for photosynthesis. This can lead to a decrease in the plant's food production as it may not receive the necessary light energy required for photosynthesis.
Since this is in Plant Biology, I'll assume we're talking about chlorophyll. Chlorophyll is a green pigment, which means that it reflects green light. It "traps" (absorbs) other frequencies, such as red and blue.If you were to confine a green plant in green light, it would perish, but if you kept it in red light, it would hang on (though full spectrum (white) light is still better).
actually why do you want it to kept in a cupboard when there is no light
Diminish significantly. Plants are green because that is the color they are reflecting into the world and not absorbing the photons at that wave length. Google chlorophyll to see what wave lengths this pigment absorbs.

Flower arrangements will stay fresh looking longer if kept in the refrigerator, but how can you enjoy them if they're in the frig?
The plant kept in light likely continued to grow through photosynthesis by converting light energy into chemical energy for growth. The plant kept in the dark likely didn't grow much, as it depends on light for photosynthesis to produce energy for growth.
Plants are green because they do not absorb green light, but reflect or transmit it. The light they absorb is mostly from the blue and red ends of the spectrum. So if a plant is kept in green light it will not be able to absorb it and so will not be able to carry out photosynthesis.
the walls are kept gree to avoid the reflection of light and to make a pleasant and soothening feel for the eyes of the theater staff and doctors.
We do not know as this happened before records were kept.
A seed is typically found within the fruit or seed pod of a flower. After the flower is pollinated and fertilized, the ovules within the ovary develop into seeds. The seed is often located at the center or within the swollen ovary of the flower.
A red rose kept the beast alive in the Disney's antimated movie of Beauty and the Beast.
