Objectives and Contextualisation
The subject introduces students to the functional processes of mineral nutrition and metabolism of plants. An integrating vision of these basic mechanisms of Plant Physiology is essential to understand the complexity of the growth and development of plants and their relationship with the environment, subjects that will be treated in subjects taught in later courses.
The main training objectives of this subject are:
Describe the functional mechanisms of plants and their regulation through external and internal factors
Integrate the functional processes of the plants from the different organizational levels within the plant organism
Identify the crucial discoveries in the history of Plant Physiology and evaluate their meaning for subsequent scientific development of the discipline
Competences
- Apply statistical and computer resources to the interpretation of data.
- Be able to analyse and synthesise
- Be able to organise and plan.
- Carry out functional tests and determine, assess and interpret vital parameters.
- Develop a historical vision of biology.
- Students must be capable of collecting and interpreting relevant data (usually within their area of study) in order to make statements that reflect social, scientific or ethical relevant issues.
- Students must be capable of communicating information, ideas, problems and solutions to both specialised and non-specialised audiences.
- Students must develop the necessary learning skills to undertake further training with a high degree of autonomy.
- Understand the processes that determine the functioning of living beings in each of their levels of organisation.
Learning Outcomes
- Apply statistical and computer resources to the interpretation of data.
- Be able to analyse and synthesise.
- Be able to organise and plan.
- Consolidate understanding of physiological processes in plants with the aim of putting this to practical use.
- Describe the functional mechanisms of plants and how these are regulated by internal and external factors.
- Identify the crucial discoveries in the history of plant physiology and assess their significance in the subsequent development of the discipline.
- Integrate the functional processes of plants, from the different levels of organisation to the whole plant organism.
- Students must be capable of collecting and interpreting relevant data (usually within their area of study) in order to make statements that reflect social, scientific or ethical relevant issues.
- Students must be capable of communicating information, ideas, problems and solutions to both specialised and non-specialised audiences.
- Students must develop the necessary learning skills to undertake further training with a high degree of autonomy.

Methodology
Lectures
During the lectures the professor explains the fundamental mechanisms of the functioning of the plants regarding the processes of nutrition and metabolism, establishing the relationships between them and clarifying basic concepts necessary for their understanding.
The methodology is mainly of verbal communication, accompanied by visual schemes. Teacher's direct questions to students during the class are indicative of the student's degree of follow-up. Bibliographical references and other sources of information are given to foster self-study.
Seminars
The main purpose of the seminars in this subject is to promote the knowledge of the general and transversal competences of the students.
Teaching methodology is based on the exposition and discussion of case studies and / or problems posed by the teacher to the students to solve them in a group, present them to their classmates and discuss them with them with the help and guidance of the teacher .
Laboratory practices
Some of the topics covered in the theory class are visualized through laboratory testing.
The student will get familiar with protocols and basic techniques of a Plant Physiology Lab. and learns to represent and interpret the results obtained in its own experiments
The student will gain access the protocols and practical guides through the Virtual Campus.
Tutoring
In tutorials in groups and individuals, the teacher tries to help the student solve their doubts about the concepts of the subject and guide them in their studies.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
Written exams that include the evaluation of the contents of the lectures.
There will be two eliminatory tests corresponding to each of the parts in which the program has been divided.
To be able to pass the subject, a minimum grade of 5 must be obtained in each of these parts. The weight of each partial exam in the theory mark is 50%. The weight of the theory mark in the final grade is 70%.
To improve the mark, or to pass the marks below 5, you can do a recovery at the end of the course of each of these exams in a final examination of recovery. The minimum mark to pass the subject to the final examination of recovery is 5.
In the case of submitting to improve the mark of a partial exam, the note of the recovery exam is counted.
To be eligible for this retake process, the student should have been previously evaluated in a set of activities equaling at least two thirds of the final score of the course or module. Thus, the student will be graded as "No Avaluable" if the weighthin of all conducted evaluation activities is less than 67% of the final score".
The note of lab practic represents 20% of the final mark of the subject. A final individual written test will be done on the last day of the practical course and it will account for 80% of the mark of the lab practice. The practice notebook will be carried out in groups and will account the remaining 20% of the mark of the lab practice. The notebook will be delivered via Virtual Campus one week after the end of the practical course.
Attendance to lab practices is mandatory. In the event of non-justified assistance, it can be recovered through assistance to another group or, if it is not possible, by means of substitute work. There is no second chance to recover the exam of lab practices.
Participation in the seminars and the quality of the works and / or problems resolved and presented account for 10% of the final mark
The subject will be approved when the student fulfills the conditions to be able to pass it and the resultant note of the different evaluations (exams, practices and seminar) is ≥5.0.
Students who can not attend an individual assessment test for justified cause (such as illness, death of a first-degree relative or accident) and provide the official documentation corresponding to the Degree Coordinator, will be entitled to take the exam in question on another date.
Every year a voluntary activity is proposed with which you can achieve a maximum increase of 0.3 points on the final mark, as long as it is greater than 5.
If the students applies for global evaluation, 80% of the mark is the final examination and 20% answers to questions of the lab guide; these questions will be made during the final examination
