which plants are usually non green and have no leaves
Answers
Yes. For starters there are ornamental plants, like begonia cultivars, where the chlorophyll that makes the leaves green is masked by other pigments. These are rare in the wild; they are bred by gardeners for their ornamental effect.
Then there are the plants that do not get their food from photosynthesis. This is a kind of retrograde specialist evolution, the way some birds have lost the ability to fly, or some cave-dwelling fish are blind. Some of these plants, like the orchids that have been mentioned, rely entirely on rotting organic matter in the soil, and are called saprophytes. Others are parasites, mostly of other plants. Broomrape is an example. All of these are found in the wild; in fact most are not easy to cultivate.
