If they stay in the dark, they would have no source of energy to produce their own food (carbohydrates) through photosynthesis. Without carbohydrates, plant cells will not survive and finally die.
However, as long as the roots remain alive and continue to extract water and mineral salts from the surrounding soil, the plant will also remain alive because it is able to extract these essential substances from its lower leaves which act as a form of ‘food storage’.
what happens to indoor plants if they are kept in the dark?
If a house plant is kept in complete darkness it will still survive but eventually the roots will die and the plant will slowly die. It should not be forgotten that plants get all their nourishment from the surrounding air, soil, water and sunlight whether they are grown indoors or outside.
Some small houseplants will continue to grow during darkness because they are able to store carbohydrate in their roots, stems and lower leaves. But most plants stop growing altogether when there is insufficient natural or artificial light available .
Note: It is a good idea to turn off any grow lights at night if you want your house plants to rest.
Can house plants survive in the dark?
House plants can survive in the dark but only for a short time. If they are given water and occasional light, they will be able to produce food.
Some people hang their house plants up near a window where there is some sunlight and others use special grow lights which emit red and blue light wavelengths (specific to plant photosynthesis).
The bulb should be close enough to the plant so that it receives the correct amount of red and blue light but not too close which may burn its leaves.

Note: Please do not place sensitive plants in complete darkness. They need some available light to photosynthesize and produce carbohydrates.
do plants need darkness?

Which plants does not need sunlight?
Plants that do not need sunlight are called Shade plants. Some examples of shade plants are:
