Common characteristics of the Integrated Course unit

Prerequisites: A basic knowledge in Biochemistry, Molecular and Cell Biology and Plant Biology is required.
Target skills and knowledge: The main objective of the course is the comprehension of the functional processes involving an exchange of matter, energy or information, in cells, tissues and organisms in animal and plant systems.
1. To be able to describe the processes of exchange of matter, energy and information at the level of single animal and vegetal cells as well as tissues;
2. To be able to describe the molecular bases that underlie bioelectrical processes and the codification of information through them;
3. To be able to describe the physiological and molecular bases of the mechanisms of absorption and assimilation of nutrients in plants.
4. To be able to describe the bases of motility at the level of the muscular apparatus in its various structures;
5. To be able to describe the molecular basis of information transfer through chemical signals;
6. To be able to use appropriate terminology;
7. To be able to organize scientific reasoning with logical precision.
Examination methods: Candidates must pass a written examination with open-ended questions on the different topics. In addition to open-ended questions, the assessment in Plant Physiology will be also based on multiple-choice questions.
Assessment criteria: The answer to each question is evaluated numerically with respect to:
1. Completeness of the acquired knowledge
2. Expressive clarity and correct use of scientific terms
3. Consequentiality and logical coherences in the answer
4. Presence of errors.
The total score of the exam results from the sum of the scores reported in the individual answers.
The preparation of a written report on the lab experiments, and its delivery within the indicated times, is a prerequisite for the evaluation of the exam.
The final score will be the weighted mean between the single scores obtained in General Physiology and in Plant Physiology
