  Plant Kingdom  The plant kingdom is the study of various subgroups of plants each one having special features. Plant kingdom classification has changed over time. Earlier, Monera and Fungi were also a part of the plant classification but now they are not a part of the plant kingdom. Recently, the plant kingdom has been divided under  Algae, Bryophytes, Pteridophytes, Gymnosperms  and  Angiosperms . 1. Algae : Algae are aquatic organisms containing chlorophyll. These organisms are autotrophic in nature and sometimes occur in association with fungi and other animals such as lichen and sloth bear. Mostly, algae occur in moist stones, fresh water, stones and wood. Based on its size, algae can be  Chlamydomonas   (microscopic unicellular),  Volvox  (colonial forms),  Ulothrix  and  Spirogyra  (filamentous). These organisms are usually vegetative in nature and reproduce sexually as well as asexually. Algae reproduce asexually by forming different types of spores, commonly known as  Zoospor
