What plants need darkness in order to live?

Which plants need a dark period in order to grow. Lets assume that it's not a consumable crop and that it doesn't flower or isn't needed to flower. Is there a way to find out, or a list somehow?

What plants need darkness in order to live?
Some plants do require daily darkness to grow normally. For example, tomato plants receiving 24 hours per day of light get lesions on their leaves. Other plants, such as some houseplants, seem to grow fine with continuous electric


light. Some plants require a daily light period (photoperiod) of less than a certain number of hours in order for them to produce flowers. These are called short day plants. Short day plants, such as chrysanthemum and poinsettia, would certainly require some daily darkness in order to be able to produce flowers.

Reply:all plants can go through living with out sunlight ... sunlight just causes photosynthesis and creates color all you need to do is keep watering
Reply:Actually, all plants need dark periods to grow. That's because many plants will undergo oxygen respiration in the dark, as well as regain water lost during the day. Many plants also undergo Crassulic Acid Metabolism, where, in order to prevent water loss during the hot tropical day, they sequester carbon dioxide at night in Crassulic acid, and then use this store of carbon dioxide to fuel photosynthesis during the day.
Reply:A mushroom walked into the saloon and ordered a round of drinks for everybody. The bartender said, " Your a nice guy!" and the mushroom replied, "No, I'm a fungi !!".


Do a google search for fungi and it should answer your question there.
