what is the plant kingdom
Plants. You are probably quite familiar with the members of this kingdom as it contains all the plants that you have come to know-flowering plants, mosses, and ferns. Plants are all multicellular and consist of complex cells. In addition plants are autotrophs, organisms that make their own food.With over 250,000 species, the plant kingdom is the second largest kingdom. Plant species range from the tiny green mosses to giant trees.Without plants, life on Earth would not exist! Plants feed almost all the heterotrophs (organisms that eat other organisms) on Earth.hen Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals. But the use of the microscope led to the discovery of new organisms and the identification of differences in cells.
