PLANT KINGDOM CLASSIFICATION | 5 Major Divisions in Plant Biology

PLANT KINGDOM CLASSIFICATION

In this tutorial, we will learn about the Plant Kingdom Classification which is one of the major topics in Plant Biology. All living organisms are classified into five broad kingdoms – Monera, Protista, Fungi, Animalia and Plantae. PLANT KINGDOM CLASSIFICATION Previously many members of Fungi, Monera and Protista which had cell walls were classified under […]

Animal Kingdom Facts in Brief and Interesting Points

If we look around, we can see a wide variety of living organisms.   In earlier times it was quite cumbersome to remember all the characteristics of each organism separately. Thus all the organisms were classified into groups and subgroups depending on common anatomical and morphological characteristics, phylogenetic relationships, reproductive systems, etc. All living organisms […]
