Do plants need total darkness?
Plants cannot survive in total darkness. All plants, with the exception of a few that live on other organisms, use a process called photosynthesis to obtain the energy they need. The vast majority of plants are autotrophs—they are self-feeding and require sunlight to survive.Click to see full answer. Moreover, do plants grow in the dark?…

Plant Growth in Darkness Plants grow fast in the dark, and do so because they operate on circadian cycles. In simplistic terms, it makes sense that plants would grow at night since daylight activity consists of absorbing light for photosynthesis. how long can plants live without light? Some really shade-loving plants will even do fine if they only get 3 to 4 hours. There are also light amounts that are important for triggering a flowering cycle, rather than actual survival of the plant. Similarly, what happens to plants in the dark? The biggest change in plant metabolism in the dark is that they stop photosynthesis, because that is a biochemical process that needs light to happen. This is how plants make their food, which happens in the leaves as long as the light is shining.Can a plant grow without sunlight?No plant can live without sunlight forever. The sun provides energy to the plants in the form of photons. So if you want to grow a plant without sunlight, you’ll have to find a source of photons for the plant. A torch, a light bulb or any other artificial light also emits energy in the form of photons.
