The external morphology of large living entities depicts variations as well as similarities in their structures. Likewise, if viewed internally too, there are similarities as well as dissimilar properties. The chapter covers the internal structure and functional arrangement seen in higher plants. Plant anatomy involves the analysis of the internal structure of plants.
The chapter covers the following subtopics – tissues, tissue system, the anatomy of dicotyledonous and monocotyledonous plants and secondary growth.
