Prerequisites

There are no official prerequisites, but it is advisable for the student to review the contents related to the subject of Botany.

Objectives

Throughout this course, students must acquire the knowledge that gives them a vision as fully as possible of the knowledge bases and the diversity of cryptogamous plants, from a functional, systematic and phylogenetic perspective. It should also allow it to place each group in an ecological context, in relation to the number of species, habitat and way of life, position within the ecosystems as well as their importance in relation to their interest in the activities of management of the natural environment .

The specific training objectives are:
- Introduce to the students the main structuring concepts of the study of cryptogames
- Understand the systematics and phylogenetic relationships between the main groups of organisms as a result of evolutionary and adaptive processes.
- Know the main levels of organization and biological patterns of organisms.
- Give some knowledge about morphological features, biological cycles, ecological importance and highlight the biotechnological importance of the main groups of organisms.

Learning outcomes

  1. Be able to analyse and synthesise.
  2. Develop a sensibility towards environmental issues.
  3. Students must have and understand knowledge of an area of study built on the basis of general secondary education, and while it relies on some advanced textbooks it also includes some aspects coming from the forefront of its field of study.
  4. Students must be capable of applying their knowledge to their work or vocation in a professional way and they should have building arguments and problem resolution skills within their area of study.
  5. 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.
  6. Students must be capable of communicating information, ideas, problems and solutions to both specialised and non-specialised audiences.
  7. Students must develop the necessary learning skills to undertake further training with a high degree of autonomy.
  8. Analyse a situation and identify its points for improvement.
  9. Propose new methods or well-founded alternative solutions.
  10. Critically analyse the principles, values and procedures that govern the exercise of the profession.
  11. Propose viable projects and actions to boost social, economic and environmental benefits.
  12. Take sex- or gender-based inequalities into consideration when operating within one's own area of knowledge.
  13. Identify and classify the plants.
  14. Analyse and interpret the development, growth and biological cycles of plants.

Teaching methodology and training activities

The subject consists of two types of teaching, lectures and seminars, with an integrated program so that the student must relate throughout the course content and activities scheduled to achieve the competencies indicated


Participatory lectures: The student must acquire the scientific-technical knowledge of this subject by attending these classes and complementing them with the personal study of the topics explained. The teaching of each subject will be based on a theoretical presentation with student participation.


Lab sessions: one of the main objectives will be the knowledge of the different groups of cryptogams, their characteristics and their ecology. The students must learn the correct way in terms of handling the different taxa and their conservation.


Seminars: will be based on exhibitions that students will have prepared and will deal with issues related to the subject and will allow the students to reflect and personally work on the topics discussed. As a complement to the seminars, issues related to the subject that may be discussed by students and teachers in the virtual campus forum will be considered.


Field trips: two field trips will be made to study the main studied taxa of bryophyte and pteridophyte algae \"in situ\". Equally important will be able to establish the main ecological parameters of the groups that are seen in the field.


IA use: Model 2 - Restricted Use: For this subject, the use of Artificial Intelligence (AI) technologies is permitted exclusively in support tasks, such as bibliographic or documentation searches in the work of creating Powerpoint presentations. The student must clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how these have influenced the process and the final result of the activity. The lack of transparency in the use of AI in this assessable activity will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in serious cases.


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.

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
First 30% 2.5 0.1 1, 2, 8, 9, 10, 11, 13, 14
Practical exam 20% 2 0.08 1, 5, 13, 14
Second mid-term theoretical exam 30% 2.5 0.1 1, 2, 8, 9, 10, 11, 13, 14
Evaluation of the presentations in the seminars, attendance and attitude in field trips and other autonomous and supervised activities 20 2 0.08 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12

The evaluation of the subject will be individual and continuous through the following tests:

- Two theoretical eliminatory exams (each one is 30% of the overall mark). Two partial tests eliminatory matter when the grade obtained by the student is equal to or greater than 5. There will be a recovery test where you can recover the partial no superats.Per participate in the recovery, the student must have been previously evaluated in a set of activities the weight of which equals a minimum of two thirds of the total grade of the subject or module. Therefore, the students will obtain the \"Not Evaluable\" qualification when the evaluation activities carried out have a weight lower than 67% in the final grade \"

- Evaluation of the seminars and autonomous activities (20% of the global mark). The oral presentation of a topic within the scope of the seminars will be evaluated (content, synthesis capacity, rigor in the expression, quality of the documentary sources and adaptation to the established time) as well as the participation and attendance to seminars and field trips. On the other hand, there will also be an evaluation on the knowledge obtained in the field trips.

-Practical exam (20% of the overall score). Attendance at practical sessions (or field trips) is mandatory. The students will obtain the grade of \"Not Evaluable\" when the absence is superior to 20% of the programmed sessions.

 - Unique evaluation: Students who take the Unique evaluation must complete the laboratory practicals (PLAB) in presential sessions as well as the Field courses (PCAM). Attendance will also be compulsory for the seminars (SEM), these with their own evaluation, with weight on the final mark as in the continuous evaluation. The unique evaluation consists of a single synthesis test on the contents of the whole theory programme plus the contents of the PLAB and PCAM. The mark obtained in the synthesis test is 80% of the final mark of the subject, the mark obtained in the seminars is the remaining 20%. 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 as for the continuous evaluation.
