Objectives

The Environmental Plant Physiology is compulsory and is taken in the second semester of the second year after having completed the compulsory subject of Plant Physiology.

The training objective of this subject is centered in the acquisition of competences within the framework of the theoretical and practical training of the student.

The Environmental Plant Physiology has the training objectives of acquiring knowledge at the organizational level of the organisms and their physiology in front of internal and external factors. Another aim is to identify the mechanisms of adaptation to the environment.

Learning activities and methodology

Title Hours ECTS Learning outcomes
Study 35 1.4 KM34
Lecture of papers 30 1.2 KM34
Magistral lectures 32 1.28 KM33, KM34, KM35
Laboratory practices 12 0.48 KM34, SM35
Field trip 3 0.12 KM33, KM34
Tutorials 6 0.24
Reports 20 0.8 KM33, KM34
Seminars 5 0.2 KM33, KM34, SM36

The teaching methodology combines magisterial classes of 50 minutes with ICT support (available virtual campus) and debate in a group of cases of study. As well as tutorials, personal study, and laboratory practices where individual and team work is combined.

Seminars promote the capacity for analysis and synthesis, critical reasoning through activities such as written and oral presentation in public of works, assessment and critical discussion, commentary of videos, resolution of questions related to the treated subjects, etc. In the seminars the student can work individually or in small groups.

Laboratory practices are understood as an autonomous process based on guided observation and support material during practices. Students will also have to produce the results obtained, performing the relevant calculations with the teacher's support and, where appropriate, respond to the questions raised in the scripts / memoirs.

The personalized or group tutorials will be used to clarify concepts, establish knowledge acquired and facilitate the study to the student. They will also be used to resolve doubts about the work presented in the seminars.


The field trip, guided and supported by the teaching staff, will allow students to analyse and discuss in situ various topics covered in the lectures related to plant acclimation and adaptation responses to the environment.


For this course, the use of Artificial Intelligence (AI) technologies is permitted exclusively for support tasks, such as bibliographic or information searches, text correction, or translations. For seminar/case study submissions, students must clearly identify which parts were generated using AI technology, specify the tools used, and include a critical reflection on how these tools influenced both the process and the final outcome of the activity. Lack of transparency regarding AI use in this assessed activity will be considered academic dishonesty and may result in partial or full penalties to the grade, or more serious sanctions in severe cases.

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 15% 1 0.04 KM34, KM35, SM36
Laboratory practices 15% 0 0 KM34, SM35
3rd test 23% 2 0.08 KM33, KM34, KM35
2nd test 23% 2 0.08 KM33, KM34, KM35
1rst test 24% 2 0.08 KM33, KM34, KM35

The specific and transversal competences of this subject will be evaluated by means of written tests (exams), thematic works delivered in written form, questionnaires filled out, oral presentations; Participation in seminars and tutorials.

- The written tests are eliminatory and a minimum grade of 4 is required to make an average between the three.The final mark of this part corresponds to the % of the three partials, requiring a minimum grade of 4. If you want to raise a grade, you must take the final test and in no case will the partial grades be saved.


- Laboratory practices: Attendance is compulsory. The weight of the practices in the final grade of the subject is 15%. A final individual written test of the practical course will be done 15 days after the end of all groups and it will account for 80% of the practice grade. The practice notebook will be carried out in groups and will account the remaining 20% of the mark. The notebook will be delivered via Virtual Campus one week after the end of the practical course.

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

- Seminars: The quality of the preparation and presentation of assignments or oral presentations, as well as the answers to the proposed questions, will be assessed. Attendance at seminars is mandatory and accounts for 15% of the final course grade. Assessment activities carried out during the seminars cannot be retaken.

Absences that are duly justified in accordance with UAB regulations will not result in any penalty. In the case of an unjustified absence, the seminar grade will be reduced according to the following criteria:

1 absence: 20% reduction of the seminar grade.

2 absences: 40% reduction of the seminar grade.

3 absences: 80% reduction of the seminar grade.

More than 3 unjustified absences: the course will be considered failed.


To pass the course, students must obtain a minimum grade of 5.0 in both the written examination and the practical component.The field trip is mandatory.


To be eligible for the resit examination (first, second or third midterm examination, or the final examination), students must have previously completed assessment activities representing at least two-thirds (67%) of the total course grade. Students whose completed assessment activities account for less than 67% of the final course grade will receive a grade of "Not Assessable".


This course offers a single assessment option consisting of one comprehensive examination covering the entire theoretical syllabus. The examination will include essay-style questions, and the grade obtained will account for 70% of the final course grade.

Assessment of the practical sessions and seminars, including the submission of the corresponding assessment evidence, will follow the same procedures as those established for continuous assessment.


Any irregularity committed during an assessment activity (including academic fraud, plagiarism, or the improper use of Artificial Intelligence (AI), unless such use is explicitly authorised in the course guide) that may lead to a significant alteration of the assessment outcome will result in a grade of 0 for that assessment activity. If the course guide establishes that obtaining a minimum grade in that assessment activity is an essential requirement for passing the course, or if multiple irregularities are committed in the assessment activities of the same course, the final grade for the course will be 0. In addition, students who commit any of these irregularities may be subject to disciplinary proceedings in accordance with the University's regulations.
