OVERVIEW

The course deals with plant diversity in natural environments, illustrating the evolutionary lines and plant taxa, with particular reference to higher plants.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the acquisition of the main knowledge on evolutionary lines, botanical nomenclature rules, taxonomic groups, including the characteristics of the main families of the Italian Flora and the use of analytical keys for their identification. Understanding the meaning and value of biodiversity.

AIMS AND LEARNING OUTCOMES

The course provides the basis for knowledge of plant taxonomy and biodiversity of plants in ecosystems, and the need for conservation. The concepts provided are preparatory to the courses chosen from the botanical topic.

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

- know the reproductive cycles of the main plant taxonomic groups;

- distinguish the main taxonomic groups on a morphological base;

- describe the structure and functions of reproductive organs of spermatophytes;

- know the main Angiosperm families and their use in daily human activities;

- use the dichotomous recognition keys for spermatophytes and describe the floral characteristics with floral diagram formulas.

PREREQUISITES

Students are required to have a basic knowledge of cytology and developmental biology

TEACHING METHODS

The teaching consists of lectures and exercises in the classroom, laboratory and field.

Lectures in the classroom will be delivered through a multimedia presentation.

Laboratory exercises include preparation of slides concerning plant histology and anatomy. The Lab activities will take place in equipped laboratories.

The exercises in the classroom and in the field will provide a direct observation of samples or plant specimens.

SYLLABUS/CONTENT

The course will deal with the following main argument:

- Introduction to systematic botany: Taxa and nomenclature; taxonomic systems. Metagenetic cycles

- Eukaryotic algae: generalities, morphology, organization, reproduction and cycles. Systematics: Rhodophyta, Phaeophyta, Chrysophyta, Euglenophyta, Clorophyta, Charophyta.

- Relief of plants from the aquatic environment Terrestrial plants: general taxonomic scheme.

- Embryophytes: differences between Bryophytes and Tracheophyte

- Bryophyta: generality, morphology, organization, systematics, reproduction and cycle

- Pteridophyta (vascular cryptogams): general features, morphology and organization, reproduction and cycles of pteridophyte isosporea and heterosporea.

- Spermatophyta: general characteristics; egg and seed, pollen.

- Gymnosperms: generality, morphology and organization; reproductive organs, reproduction and cycle; Cytopophytes, Gingkophytes, Coniferophytes and Gnetophytes.

- Angiosperms: generalities, morphology and organization; reproductive organs; flower, inflorescences; fruit; reproduction and cycle; Dicotyledons and Monocotyledons

Laboratory course:

- Metamorphosis of root, stem and leaf.

- Flower and inflorescences of Angiosperms: morphology and functions. Morphological and anatomical characteristics of the fruit with relevant examples.

- Elements of phytognosy and use of dichotomous keys for the recognition of the main families of Dicotyledons and Monocotyledons. Presentation in the field of the main plant groups: mosses, ferns, Gymnosperms and Angiosperms with direct experiences.

- Visit to the Hanbury Botanical Gardens for direct observation of all the topics covered in the course.

- Field trip for live observations and harvesting of herbarium preparation material

Class schedule

BOTANY AND LABORATORY (2° MODULO)

EXAMS

EXAM DESCRIPTION

The exam includes a written test during the course related to general botany and one related to laboratory exercises. To access the laboratory test, attendance at laboratory exercises must be at least 75%. The final exam also includes the presentation of a small herbarium; the overall grade (80813) consists of the weighted average of the marks obtained in the various tests of the two modules. The partial grades are valid only for the summer session (June, July and September) of the current academic year.

Students who do not take or do not pass the tests in progress must take an oral exam on the complete course program (80813).

Students who hold or pass only one of the in itinere tests of general botany and systematic botany can retrieve the missing proof with a single attempt, within the appeals of June and July of the current academic year.

ASSESSMENT METHODS

Both for the theoretical part and for the laboratory, final tests are foreseen to ascertain the effective acquisition of basic knowledge of botany. Upon completion of the evaluation, the presentation of a small herbarium will be required, with discussion on the prepared samples.

Those who have not taken or passed the tests in itinere will have to take a classic oral exam, concerning all the topics covered during the frontal lessons and the Laboratories (Bot. Gen. + Bot. Sist. + Lab), including recognitions of an anatomical section and of plant samples.

The oral exam will aim to assess not only if the student has reached an adequate level of knowledge, but if he has acquired the ability to link structure and functions in plants.

Exam schedule

FURTHER INFORMATION

Attendance at the theoretical course strongly recommended and which will allow an adequate preparation to take the test in progress. To take the final written test of the Laboratory, an attendance of 75% at the laboratory activities  is necessary.
