Objectives and Contextualisation

The Integrated Laboratory II is the second laboratory course of a set of six that are distributed throughout six semesters of the first three years of the Genetics Degree.
These laboratory courses aim to provide a solid basis for experimental procedures, techniques and skills in genetics and related sciences.
The laboratory practices reinforce the theoretical concepts acquired in the theory classes, allowing to fully understanding the essential dialogue between conceptual and experimentation that comprise the genetics science.
The Integrated Laboratory II has as its training objectives the acquisition of experimental competencies in 3 specific modules:

  • Animal and Plant Biology
  • Biochemistry
  • Animal Physiology

Animal and Plant Biology


To learn how to recognize cyanobacteria, photosynthetic aquatic eukaryotes, higher plants and fungi through their morphological characteristics.

To identify the fundamental structures and their relevance through their most common representatives, in order to understand the evolution and morphological diversity.

Plant physiology

To determine the Water Potential (Ψ) of a fresh vegetable tissue and observation of the plasmolysis phenomenon.
To study the Hill Reaction in a suspension of isolated chloroplasts, using DPIP as an artificial electron acceptor. The inhibition of water photolysis at the level of Photosystem II using a synthetic inhibitor, DCMU (a product known commercially as Diuron ® and used as an herbicide in agriculture) is simultaneously determined.
To determine water lost through transpiration and transpiration rate of plants under different environmental conditions.


To identify the anatomical and morphological characteristics of different animal groups.
Taxonomical identification and location ofthe different animal species observed.
To learn how to use dichotomous keys for animal determination.

The subject is taught in small groups of students (maximum 20 per session) in the laboratory. Students have a manual or practice guide for each Module. It is necessary to read the corresponding part of each session carefully before starting the practice to obtain the maximum advantage. Students will have to produce the results obtained.

Module - Animal and Plant Biology


In each practical session it is mandatory for the student to bring their own dressing gown and the practice guides and the description sheets, both will be available on the Virtual Campus or when indicated by the teaching staff. You also have to bring a notebook, where each student will write down the observations made. For the realization of the practices, the students will workalone or in pairs and under the supervision of the professor. At the beginning of each session the teacher will make a brief theoretical explanation of the content of the practice and of the experiences and observations to be carried out by the students.

Plant Physiology

The student must prepare previously each practice session. You need to dedicate approximately 1 hour to review the theoretical concepts, the foundation of the practice, the methodology to follow and the objectives that you want to achieve.

After the preparation of the practice, another approximate time will be necessary to prepare the results obtained in each practice and answer the questions in the practice guide.


Module - Biochemistry

Autonomous process based on guided observation and experimentation. Students will have to elaborate the results obtained and / or answer the questions posed in the practice manual.

Module - Animal Physiology

The programmed training activities include time of directed learning and time of self-learning.

Laboratory sessions / computer classroom: Classroom sessions to which students develop protocols and experimental situations contained in the practice scripts. These sessions are always carried out with a current teacher that explains the work to do and supervise the tasks that must be carried out in the laboratory / computer room.

Tutorials: Time of discussion and resolution of doubts / problems that appear during the time of directed learning or the one of autoaprendizaje. They will be done individually or in small groups depending on the requirements and the areas of the issues to be discussed. This activity will be programmed at the request of the students themselves.

Self-learning: Autonomous training activities (individual or in group) in which the student works and deepens both the content of the practical scripts and the experimental data generated in the computer lab / classroom. These activities include the reading and understanding of the scripts of practices before their development laboratory as well as the preparation of the corresponding questionnaires.


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.

Attendance to practical sessions is mandatory. Students missing more than 20% of programmed sessions will be graded as "No Avaluable"

Module Animal and Plant Biology


The use of practices will be evaluated through a small test at the end of the laboratory session (15%), and an exam (85%) consisting of two parts: Visum, and Description of a fruit / fruit or corm modification.

Plant Physiology

A final individual written test will be done on the last day of the practical course and it will account for 80% of the mark. 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.


At the end of each practice the student will have to answer a questionnaire to evaluate that he has achieved the knowledge and the specific competences of each practice. The note of this module will be calculated based on the average mark of the questionnaires.

Biochemistry module

The student's attitude in the laboratory will be evaluated, punctuality, wearing the appropriate material such as a dressing gown, goggles and practical guides, previously worked at home for the student, as well as his work in the laboratory. The student on the day the teacher will give a questionnaire that will respond outside the laboratory. The evaluation of the attitude will represent 25% of the mark, and the evaluation of its degree by using the questionnaire presented the other 75% of the total of the module's note.

Animal PhysiologyModule

The final score for this module depends on:

1 - Assistance.

Attendance to the practicals is mandatory and is considered a requirement to be evaluated. Failure to attend any of the sessions, without adequate justification in accordance with UAB regulations, implies failure of the module.

2 - Laboratory work.

Scripts and questionnaires to be completed during the practices and that will be submitted for evaluation, following the instructions of the teacher.

Individual realization

40% of the final mark.

3 - Examination of practices

Exercises including short questions and/or multiple choice questions to be taken at the end of each of the practical sessions. These tests will be conducted online through  Moodle and will be scheduled outside the academic hours and in the period between 48 hours after the full completion (all groups of practices) of the practice to be evaluated.

60% of the final grade.

A grade equal to or higher than 4.5 must be obtained in all evaluation activities in order to calculate an average grade. To pass this module, all practicals must be passed with a grade equal to or higher than 5.0. Practical sessions a grade lower than 5.0 will be recovered in a final exam, which will determine the final grade. There is no possibility of improving the final grade obtained in this module.

To pass the course, it is necessary to first approve each module with a note = 5.

Students who do not pass the different modules of the subject will be able to recover them on the scheduled date for the recovery evaluation of the subject. Students who have not passed one of the modules after the recovery evaluation willnot approve the subject. In spite of this, it will not be necessary for a repeating student to carry out the teaching activities or the evaluations of that module passed after the second enrollment. Repeaters will only have to be evaluated for the specific module that has not been exceeded. This exemption will be maintained for a period of three additional license plates.

The final grade is the weighted average of the notes of each module, where evey modul is 20% of the final mark.

To be eligible for the retake process, the student should have been previously evaluated in a set of activities equaling at least two thirds of the final score of the module.
