Learning outcomes of the course unit
The course sets the aim to transmit students the basic principles of biology necessaries to the comprehension of the basis of botany. The treated arguments will allow to the students the acquirement of tools necessaries to describe structures and functions of photosynthetic organisms from prokaryotes to protists and vascular plants. Students will obtain the basis to understand the main features of plant cells, tissues and organs and how they evolved and differentiate during time.
In particular students will be able to:
D1. Knowledge and Comprehension
To know and understand the structure, sub-structure and biological properties of plant cells, tissues and how they cooperate to form the different organs which, with their different functions, determines the plant anatomic structures. To know and understand morphogenesis, adaptations, classification and phylogeny of the main plant groups.
D2. Knowledge and comprehension application ability.
To be able to:
-utilize specific language proper of botany,
-recognize plant tissue,
-recognize structures and reproductive cycles of the different plant evolutive groups.
D3. Judge autonomy
To be able to evaluate teaching method
D5. Learning capacity
To be able to make connections between the different treated topics and between them and basis and affine disciplines. To acquire clearness in the exposition of the studied matters. To acquire a study method allowing the prosecution in the university formation. To reach the required competences for the insertion in professional activities at the end of the triennial course.

Lectures will be conducted through the aid of a POWER POINT support. It is planned to show presentations full of pictures, graphs and diagrams that enable maximum understanding and synthesis of the topics covered.
Assessment methods and criteria
The assessment of the success of the planned course includes an written examination based on multiple answer questions (20 questions) and open questions (3 questions). The time disposal for written examination will be 1 hour and 15minutes. The multiple answer questions will cover the entire course program and for any correct answer the students will gain 1.5 points; to obtain a pass mark at least 12 questions should be answered correctly. Two of the three open question will be on topics regarding plant cytology, histology or anatomy and one of evolutive botany. Answering to these questions students will the possibility to organize their own argumentation making proper connections between of the different subjects treated during the course. In this way it will be determined whether the student has acquired general and particulars knowledge of the course contents, he gained the ability to understand the function of plants and has the basic skills to recognize and describe the plant species studied. Contribution to the mark obtained for the answer to the open questions will be calculated on the basis of correctness of the acquired knowledge, thinking and connecting ability, clearness of exposition and language property. Both part of the examination must pass the mark and the final mark will be an average of the marks obtained in the two parts of the examination.
