Theory classes

In the theory classes, the teacher explains the fundamental mechanisms of the functioning of plants, referring to the processes of growth and metabolism, establishing the relationships between them and clarifying basic concepts necessary for their understanding. The methodology is mainly oral presentation with digital accompaniment. Teacher-student interaction is worked with questions, reasoning, anecdotes or any other activity that promotes teacher-student communication and gives an overview of the concepts developed in the contemporaneity of the explained syllabus. The basic bibliographic references and other sources of information are given to encourage independent study.

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 solve them in groups, present it to their peers and discuss it with them with the help and guidance of the teacher .

Practical classes

Some of the topics discussed in the theory class are visualized through an experiment in the laboratory. The student becomes familiar with protocols and basic techniques of a Plant Physiology laboratory and learns to represent and interpret the results obtained in his own experiments. The student will be able to access the protocols and practice guides through the Virtual Campus.

Tutoring

In the group tutorials, the teacher tries to resolve doubts about the concepts of the subject and guide the students in their study.

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

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Seminars 10% 0.5 0.02 CM29, CM30, KM43, SM41
Laboratory practices 20% 0.5 0.02 CM30, KM45, SM41
Exam 70% 3 0.12 CM30, KM43, SM42

The evaluation of the theoretical part is done through written exams that include the evaluation of the contents of the classes. There will be two qualifying tests corresponding to each of the parts into which the syllabus is divided.

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 grade is 40% for the first partial exam and 60% for the second partial. The weight of the theory grade in the final grade is 70%.

To pass grades lower than 5, the final recovery of each of these exams must be done in a final recovery exam. In order 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 evaluate the laboratory practices, an individual written test will be done that will represent 80% of the practice grade. The date of the test will be determined each year according to the calendar by the degree coordination. The preparation of the practice script will be done in groups and will represent the remaining 20% ​​of the grade. The script will be submitted via Virtual Campus one week after the end of the practices. The final practice grade represents 20% of the total grade for the subject. Attendance at the practices is mandatory. To pass the practices, the student must attend the practice sessions (except in duly justified cases in accordance with UAB regulations) and submit the practice script within the established deadline, which is not recoverable.

The practice exam is recoverable in accordance with 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 the 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 resulting grade of the different parts (exams, practicals and seminar) is ≥ 5.0


A student will be considered to obtain the grade of Not Assessable when the number of assessment activities carried out is less than 50% of those scheduled for the subject (the two eliminatory exams, the three practical sessions and participation in seminars). Attending the final exam for retakes means in any case that the student has Attended and will be assessed.

Students who cannot attend an individual assessment 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, will have the right to take the test in question on another date.

Single assessment:

This subject includes the single assessment which consists of a single synthesis test in which the contents of the entire theory program will be evaluated. The test will mainly consist of questions to develop and some relationship, test or sentence or paragraph completion questions. The grade obtained in this synthesis test will represent 70% of the final grade for the subject.

The evaluation of practical and seminar activities and the submission of assignments will follow the same process as the continuous assessment, and the grade obtained will represent 20% and 10% of the final grade for the subject respectively.

The single assessment test will be held on the same date set in the calendar for the last continuous assessment test and the same recovery system will be applied.


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
