What are Plants - Importance and Plant Cell Diagram

Plants may be defined as multicellular organisms with photosynthetic organelles. Unlike animals, they can produce their food in the presence of sunlight and carbon dioxide. They are the eukaryotic species belonging to the Kingdom Plantae.

Initially, when the classification of organisms was made, the fungi and algae were all grouped under the category of plants. As per the strict classification now, all the fungi and certain algae, along with prokaryotes like bacteria and archaea, are removed from the classification of plants. Therefore, according to the present classification, the Kingdom Plantae includes flowering species, gymnosperms, and green algae.
