Learning objectives
Critical understanding of the logic of growth, cell differentiation and development of plants in relation to the main cell and organs functions: photosynthesis, oxygen consumption, mineral nutrition, imposition of stressful conditions.
Expected learning outcomes
Identification of the critical aspects of plant qualitative and quantitative production also in relation to the interaction with the environment, design of improvements by means of chemical, physical, biological actions. Tools for critical participation to the evolution of knowledge.
Course syllabus and organization

Single session

Responsible
Lesson period
Second semester
In the current situation, due to the Covid-19 emergency, It is expected that the teaching can be carried out, in compliance with the regulations, both remotely and in presence. If changes occur, teaching will be promptly adapted to the indications of the competent authorities.
The teaching is held synchronously by using the MS Teams platform, the lessons use presentations prepared from texts books, scientific and review articles. All the materials are present on Ariel.
Practical activities and exercises consist in activities carried out remotely and synchronously sing presentations using the MS Teams presentations carrying out assessment and calculations involving students and using JoVe videos. The material is present in Ariel

Natural products and natural metabolites. Characteristic of natural metabolites: physiological role and biosynthesis (CFU 0,5).
Practical activities in laboratory: Photosynthesis, respiration, membrane transport. (CFU 1)
Prerequisites for admission
Morphological and functional organization of the plant. General and inorganic chemistry: chemistry of the elements components of living organisms. Chemistry of the organic molecules components of living organisms. Physics: general knowledge of dynamics of fluids, kinetic theory of gases, thermodynamics, electric potentials and currents, electromagnetic waves. Biochemistry: general knowledge of metabolic pathways, protein biosynthesis and other molecules components of living organisms.
Teaching methods
The teaching is carried out essentially through lectures, consisting of critical illustration of slides developed by the teacher on the basis of l texts and paper published on international publications. Practical activities in laboratory are planned.
Teaching Resources
The slides illustrated and discussed in class are available on the Ariel website of the University. Scientific articles in English concerning aspects of particular interest are also provided. The following texts are suggested:
- Plant Physiology and Development - Sixth Edition. Lincoln Taiz, Eduardo Zeiger, Ian M. Møller, and Angus Murphy. 2014. ISBN: 9781605352558
- Biochemistry & Molecular Biology of Plants - 2nd Edition. Bob B. Buchanan (Editor), Wilhelm Gruissem (Editor), Russell L. Jones (Editor). 2015. ISBN: 978-0-470-71421-8
- Physicochemical and Environmental Plant Physiology, 5nd Edition. Park S. Nobel. 2020. 2020 Elsevier Inc, ISBN: 978-0-12-819146-0
Assessment methods and Criteria
The oral examination is structured in 5 open questions on different subjects of the course. Each question is evaluated with a score from 0/30 to 6/30. The overall score is given by the sum of each application ones. For the evaluation are considered different aspects, such as the accuracy of the response, the terminology used to define the process and the level of depth of the answer. Moreover, the synthesis capacity and the critical view of the topics will be evaluated.
