Plants are mainly autotrophic but a few members are partially heterotrophic such as the insectivorous plants or parasites. The plant cells have an eukaryotic structure with prominent chloroplasts and cell wall mainly made of cellulose. Plantae includes algae, bryophytes, pteridophytes, gymnosperms and angiosperms.
It should continue to be restricted. If it is not restricted, there is a chance it will become extinct. This not only has bad consequences for us, it destroys the food web as a trophic level is effectively eliminated.
