Objectives
The subject introduces students to the basic physiological concepts of plants. The subject gives an overview of plant physiology and establishes the basic operating processes through morphological, metabolic and plant nutrition concepts. The integrative 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, topics that will be covered in subjects taught in subsequent courses.
The main educational objectives of this subject are:
• Identify the crucial discoveries in the history of Plant Physiology and evaluate their significance for the further scientific development of the discipline
• Explain the functional processes of plants based on the different organizational levels within the plant organism
• Describe the functional mechanisms of plants and their regulation through external and internal factors

Theory classes
In theory classes, the teacher explains the fundamental mechanisms of how plants work, establishing the relationships between nutrition and metabolism processes for a good understanding of the syllabus. The methodology is a master class with digital accompaniment and with teacher-student interaction in terms of questions, concerns, anecdotes or reasoning to link the syllabus to current events that the students know. The basic bibliographic references used and other more interactive ones are given for the independent study of the students.
Seminars
The main purpose of the seminars in this subject is to promote students' knowledge of general and transversal skills. The teaching methodology is based on the presentation and discussion of case studies and/or problems posed by the teacher to the students so that they can solve them in groups, present them to their peers and discuss them with them with the help and guidance of the teacher . The teacher will arrange the tasks to be done in each case.
Practical classes
Some of the topics discussed in theory class are visualized through laboratory practices that help the student to better understand. In the laboratory, the student becomes familiar with protocols and basic techniques of Plant Physiology and learns to represent and interpret the results obtained. The protocols and practice guides will be uploaded to the Virtual Campus.
Tutoring
Group tutorials are held before each partial exam and the teacher resolves doubts about concepts or aspects explained during the theoretical classes.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Examinations of lecture programs | 70% | 3 | 0.12 | KM44, SM42 |
| Evaluation of lab practice and seminar | 30% | 0.5 | 0.02 | CM30, KM44 |
The theoretical part will be assessed through written exams that will include the evaluation of the contents of the theoretical classes. There will be two qualifying tests corresponding to each of the parts into which the syllabus has been divided. In order to pass the subject, a minimum grade of 5 must be achieved in each of these parts. The weight of each partial exam in the theory grade is 50%. The weight of the theory grade in the final grade is 70%.
To overcome grades below 5, a retake of each of these exams may be made at the end of the course in a final retake exam. The minimum grade to pass the subject in the final retake exam is a 5.
To improve the grade, a final exam of all the content must be taken and the grade of this final exam will be counted (that is, with the waiver of the grade obtained previously).
To participate in remediation, students must have previously been assessed in a set of activities whose weight is equivalent to a minimum of 2/3 of the total grade for the subject or module. Therefore, students will obtain the grade of \"Not Assessable\" when the evaluation activities carried out have a weighting lower than 67% in the final grade. \"The practical grade represents 20% of the final grade of the subject. To evaluate the laboratory practices, an individual written test will be taken that will represent 80% of the practical grade. The date of the test will be determined each year according to the calendar by the degree coordination. The preparation of the practical script will be done in a group and will represent the remaining 20% of the grade. The script will be delivered via Virtual Campus one week after finishing the practicals. The final practical grade represents 20% of the total grade of the subject. Attendance at practicals is mandatory. To pass the practicals, the student must attend the practical sessions (except in cases duly justified in accordance with UAB regulations) and must submit the practical script within the established deadline, the which is not recoverable.
The practical exam is recoverable according to the calendar and recovery criteria established for the subject.
Attendance at seminars is mandatory and represents 10% of the final grade for the subject. Activities carried out during seminars are not recoverable. Absences justified in accordance with UAB regulations will not entail any penalty. In the event of an unjustified absence, the grade corresponding to the seminars will be reduced according to the following criteria:
1 absence: 20% reduction in the seminar grade.
2 absences: 40% reduction in the seminar grade.
3 absences: 80% reduction in the seminar grade.
More than 3 unexcused absences: the subject will be considered failed.
Seminars are not recoverable.
The subject will be passed when the student meets the conditions to be able to pass it and the grade resulting from the different assessments (exams, practicals and seminar) is ≥5.0.
Students who cannot attend to an individual evaluation test for a justified reason (such as illness, death of a first-degree relative or accident) and provide the corresponding official documentation to the Degree Coordinator, they will have the right to take the test in question on another date.
Single evaluation:
This subject includes a single evaluation that consists of a single synthesis test in which the contents of the entire theory program will be evaluated. The test will consist mainly of questions to be developed and some questions of relationship, test or completing sentences or paragraphs. The grade obtained in this synthesis test will represent 70% of the final grade of the subject.
The evaluation of the practical and seminar activities and the submission of work will follow the same process as the continuous evaluation, and the grade obtained will represent 20% and 10% of the final grade of the subject respectively. The single evaluation test will be held coinciding with the same date set in the calendar for the last continuous evaluation test and the same grading system will be applied. recovery.
Use of AI - Restricted Use
For this subject, Artificial Intelligence (AI) technologies are allowed to be used exclusively as a support tool for bibliographic or information searches, linguistic correction of texts, translations, improvement of writing or organization of content. These tools are not allowed to be used to generate all or part of the answers to exams, reports, assignments or other assessable activities that require analysis, interpretation of results or own scientific reflection.
The student must clearly identify any use of AI tools, specify the tools used and briefly describe how they have contributed to the development of the activity.
The lack of transparency in the use of AI will be considered a lack of academic honesty and may lead to a partial or total penalty in the qualification of the activity, or greater sanctions in serious cases.
Academic misconduct
Any irregularity committed during an assessment activity (academic misconduct, plagiarism, or improper use of AI, unless such use is expressly authorized in the course syllabus) that may lead to a significant alteration of the grade will result in that activity being graded as 0. If the course syllabus stipulates that obtaining a minimum mark in this assessment is an essential requirement to pass the course, or if multiple irregularities occur in the assessment activities of the same course, the final grade for the course will be 0. Furthermore, disciplinary proceedings may be initiated against any student who incurs any of these irregularities
