OVERVIEW

Systematic Botany deals with the diversity of the plant world, understood in a broad sense (Procarioti, Fungi, Algae, Land plants); it is one of the fundamental disciplines for the study of biodiversity which is a key element in the formation of a naturalist both as regards the knowledge of how it has come to its current expression and the applicative aspects related to its management and conservation.

AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

1) AimsThe course aims to provide students with the basic notions of Systematic Botany and the main tools for identifying plant diversity and recognizing its main components.

2) Learning outcomes

At the end of the course the student will be able to:

• present principles and methods of historical and modern systematics;

• describe the main plant groups in the broadest sense: Prokaryotes, Algae, Mushrooms and, in particular, terrestrial plants (Musks, Ferns, Gymnosperms, Angiosperms), highlighting their main characteristics, also with the help of examples;

• understand and illustrate the different trends and evolutionary stages that have led to the current plant diversity;

• illustrate the characteristics and indicate the main examples of the most important families of angiosperms;

• use dichotomous keys for the identification of vascular plant species;

• identify "by eye" the most important families and species of Italian flora.

PREREQUISITES

Concepts and basic mechanisms of biology (cell, mitosis, meiosis, cell cycles, metagenetic cycles) and of plant biology (in particular cellular organelles, tissues and plant organs)

TEACHING METHODS

Lectures, exercises in the classroom, in the laboratory and in the field.

Attendance is not mandatory, but strongly recommended, especially for lab and field exercises.

SYLLABUS/CONTENT

Introduction to plant taxonomy and systematic. Reviews taxonomic groups of bacteria (with emphasis on Cyanophyta), algae (with emphasis on Rhodophyta, main groups of Heterokontophyta and Chlorophyta), fungi (Oomycetes, Chytridiomycota, Zygomycota, Glomeromycota,  Ascomycota, Basidiomycota),  lichens. Origin of land Plants. Bryophyta ( Hepaticopsida, Anthocerotopsida, Bryopsida). General features and evolution of vascular plants. Pteridophyta: main fossil groups, Licophytes, Monilophytes (Equisetopsida, Psilotopsida, Polypodiopsida). Topics include: taxonomic position, morphology, variety of forms, diversity of reproductive cycles in relation to evolution.

Spermatophyta: biology, ecology, systematics, speciation and evolution of seed plants. Gymnospermae: main fossil groups, Cycadales, Ginkgoales, Pinales (Conifers and Gnetophytes). Angiospermae: structure and morphology of flowers and fruits, principal taxa of  Dicotyledons and Monocotyledons.

The course  will include training in the identification of families and species of italian vascular flora with emphasis on flowering plants.

RECOMMENDED READING/BIBLIOGRAPHY

The slides of the lessons will be available on aulaweb. The notes taken during the lessons may constitute the main study basis for the preparation of the exam, but it is advisable to consult texts of the University level systematic botany and botany to verify the completeness and correctness of the notes themselves and for any further study of the topics. treated.

EXAM DESCRIPTION

The exam consists of a practical / written and an oral part.

The written evidence consists in the identification of a plant sample of Italian flora with the use of dichotomous keys, up to the species; for admission to the oral exam the written test must be passed at least up to the level of identification of the family.

The oral exam includes open questions on the topics of the program, the first including the "sight" recognition of a sample of one of the most important and / or common species or families of Italian flora.

The evaluation of the topics covered in the first teaching period will be carried out through on-going audits (multiple choice test + an open question) whose evaluation will compete for about 2/5 for the final evaluation. The in itinere verification is considered outdated if the student has achieved a score for each of the two parts of at least 8 points / 15 and an average of at least 18/30. The student who has not done or passed the on-going verification will be evaluated on the whole program for the oral exam.

Five appeals will be available in the session (June, July, September) and 2 calls for the winter session (January-February)

The practical / written test can be sustained on the dates of all official appeals, but is valid for only one academic year. To support it you must send a reservation email to the teacher at least 3 working days before the call.

The checks in progress, if exceeded, are always valid.

ASSESSMENT METHODS

The practical / written test of phytognosy serves to evaluate the student's ability to correctly use dichotomous keys for the identification of plant samples.

The oral exam is aimed at verifying the knowledge of the characteristics of the main plant taxa and the understanding of the evolutionary mechanisms that have led to the current plant diversity; moreover, through the recognition "by eye" of a sample, it serves to assess the knowledge of the main taxa, especially at the family level, of the Italian flora and the ability to quickly identify the most important diagnostic elements in the sample.

The in itinere test (optional) verifies in the first part (closed answer test on specific topics of the program) the learned notions and the ability to discern the manifestly wrong answers and in the second part (open question on a broad topic), besides the knowledge acquired, the ability to identify the most important and characteristic elements that allow to describe a taxon or an evolutionary event.
