Is there such thing as a plant that does not get its energy from the sun?

Answer 1

There are certain plants that does not photosynthize.

I found this on the web regarding this issue:

Indian pipe, Monotropa uniflora, is a saprophytic flowering plant found in the northern U.S. that is almost completely white when in bloom, occaisionally tinged with pink, and does not photosynthesize. One-flowered cancer root, or ghost pipe, Orobanche uniflora, is a parasitic flowering plant. The flowers are pale lavender to whitish, stems are greenish. J. Elliott

The question was not really about photosyntesizing, only regarding Energy and From the sun.

Since all living things need energy in one way or the other, they all get energy from the sun. Either directly or indirectly by eating the nutrition from living (parasitic behaviour) or dead.

Certain fungi can also live very well without any sunlight at all, but they do get energy from dead matereal in order to grow.

I suppose one could synthesize organic material from only chemichals and various acids, and use this as a growthmedium in which fungi would thrive, possibly even the some plants as Elliot pointed out in his answer before.

Plantlike Organisms far down in sea can also live without light as long as they have access to sulfur and warmth. This is mainly due to certain bacterea that can get energy out of sulfuric reactions. This bacterea provides their host with energy, but the host also feed on dead organisms and nutritions floating in water.
