Learning objectives

<br />The course of  Plant Systematics aims at providing updated knowledges concerning the evolution of photoautotrophic organisms from Prokariotes to Spermatophytes. The students could make experience in identifying and classifying vascular plants through producing an herbarium, based on plant samples collected in the field.

Prerequisites

An adequate level of learnings concerning plant morphology, histology and citology is requested.

Course unit content

<br />A) INTRODUCTION <br />1) Plant Systematics and Taxonomy. An historical excursus from the origin of plant taxonomy to modern plant systematics. Present methodologies of plant systematics research. 2) Reproduction and sexuality in the plants. Vegetative reproduction, sporogony and sexual reproduction. Metagenetic cycles.<br /><br />B) PLANT EVOLUTION AND TAXONOMY<br />1) The Prokariotes. General features, cytology, reproduction and phylogenesis. Taxonomy: Archaebacteria and Eubacteria.
