Plant systematics is a branch of biology that includes and extends classical taxonomy, but its main purpose is to reconstruct the development of plant life.
It uses morphological, anatomical, embryological, chromosomal, and chemical data to classify plants into taxonomic categories.
Plants form evolutionary links between distinct groupings of plants in a systematic manner.
It shows how plants have evolved over time.
The comparison of morphological, anatomical, and cytological structures among different structures is based on plant systematics.
Plant systematics also serves as a foundation for genetics.
