Objectives

Vegetal Physiology is the first subject of a set of 3 that form the matter of Plant Physiology. It is compulsory and is attended in the first semester of the second year.
The training objective of this subject is focused on the acquisition of competences within the framework of the theoretical and practical training of the student.
Vegetal Physiology has as its training objectives the acquisition of knowledge of the different levels of organization of the organisms in its operation

The teaching methodology runs on lectures, virtula lectures, seminars, tutorials, personal study, as well as laboratory practices that combine individual and team work

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
2nd written test 40% 1.5 0.06 CM26, SM36
Seminars 15% 2 0.08 CM26, CM27, CM28
Laboratory practices 10% 2 0.08 CM26, CM27, CM28, SM35
1st written partial test 35% 1.5 0.06 CM26, SM36

The specific and transversal competences of this subject will be evaluated by means of written tests (exams), questionnaires, oral presentations, participation in seminars and tutorials.

The written tests will be worth 75% of the final weight of the subject. It consists of two partial tests (first partial test 35% and second partial test 40%).

Students who have not submitted to any of the written tests, or who have submitted have not approved, will have to recover the part or parts suspended in a final exam. To pass the subject, or to eliminate the subject in the partial exam, you will have to obtain a minimum grade of 5.0 in each of the written tests.

To pass the mark of the subject, students must present themselves to a final exam of the whole subject, taking into account that the mark that will be counted will be the one of this last examination (that is to say, resigning to the notes previously obtained in the subject).

To participate in the recovery, the students must have previously been evaluated in a set of activities whose weight equals to a minimum of two thirds of the total grade of the subject or module. Therefore, students will obtain the \"Non-Valuable\" qualification when the evaluation activities carried out have a weighting of less than 67% in the final grade.


Laboratory practices:

Attendance at all practical sessions is mandatory and attitude is valued. To pass the internship, the student must:

-Compulsory attendance at practical sessions (except in cases duly justified in accordance with UAB regulations)

-Compulsory delivery of the practice script within the established period.

The exam of practices is recoverable according to the calendar and the criteria of recovery established by the subject. The delivery of the practice script is mandatory and not recoverable.

For the evaluation of the practices, a final written test will be done individually that will represent 80% of the practice grade. The elaboration of the practice guide will be done in groups and will represent the remaining 20% of the grade. The script will be delivered via Virtual Campus one week after the end of the internship. The weight of the practices in the final grade of the subject is 10%.

To be able to attend, it is necessary for the student to justify having passed the biosafety and security tests that hewill find in the Virtual Campus and be knowledgeable and accept the rules of operation of the laboratories of the Faculty of Biosciences.


Seminars / Problems:

Attendance to seminars is mandatory and represents 15% of the final grade of the subject. The activities developed during the seminars are not recoverable.

The absences justified in accordance with the regulations of the UAB will not entail any penalty. In case of unjustified absence, the grade corresponding to the seminars will be reduced according to the following criteria:

1 absence: 20% reduction in the grade of the seminars.

2 absences: 40% reduction in the grade of the seminars.

3 absences: 80% reduction in the grade of the seminars.

More than 3 non-justified absences: the subject will be considered not passed.

The quality of the preparation and presentation of works or public exhibitions will be evaluated as well as the answers to the proposed questions and problems.

In the event of justified absence from a seminar, the absence may be compensated by an alternative activity, to be defined by the teaching team. If this compensatory activity is not delivered, the percentage corresponding to this seminar will be reduced in the final grade.


The final grade of the subject will result from the weighting of the different evaluation activities:

o Theory: 75%

o Seminars: 15%

o Laboratory practices: 10%

To pass the subject it will be necessary to obtain a minimum grade of 5.0 in each of the exams. In case of not achieving this minimum grade in any of the exams, the subject cannot be passed, regardless of the mark obtained in the rest of the evaluation activities.


Unique assessment:

This subject contemplates the single assessment which consists of a single synthesis test in which the contents of the entire theory program will be assessed. The test will consist mostly of questions to be developed and some shorter questions in different formats. The grade obtained in this synthesis test will account for 75% of the final grade of the subject.

The assessment of practical activities, seminars and the delivery of assignments will follow the same process as thecontinuous assessment, and the grade obtained will represent 10% and 15% of the final grade of the subject respectively.

The single assessment test will coincide with the same date fixed in the calendar for the last continuous assessment test and the same recovery system will be applied.


In this subject, the use of Artificial Intelligence (AI) technologies is not allowed in any of its phases. Any work that includes fragments generated with AI will be considered a lack of academic honesty and may involve a partial or total penalty in the grade of the activity, or major penalties in cases of severity.

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.
