Green plants have solid cell walls containing cellulose. Almost all plant members are autotrophic, producing their own energy by converting the energy of sunlight through a process called photosynthesis in organelles called chloroplasts. Due to the dominant green color of the members of this kingdom, another name used is Viridiplantae. The other name is Metaphyta. But there are also plants that are parasitic and some have no photosynthetic ability with little or no chlorophyll. Plants can also be diarecterized from the way they breed, the growth ability, and the rotation of offspring.
