Learning objectives
The aim of the course is to provide the student with the theoretical and practical notions of cellular biology through the dissertation of cellular components at the structural, compositional and functional levels and the concept of multilevel hierarchical organization. In particular, the course aims to 1) provide the basic principles for understanding the centrality of the cell in the biology of multicellular organisms; 2) to outline the characteristics of cellular specialization even at the molecular level; 3) provide application skills regarding methodological and instrumental procedures aimed above all at the observation of cellular elements in a tissue context.
In particular, the course aims to 1) provide the basic principles for understanding the centrality of the cell in the biology of multicellular organisms; 2) to outline the characteristics of cellular specialization even at the molecular level; 3) provide application skills regarding methodological and instrumental procedures aimed at the observation of cellular elements within the tissue.
The course will also provide the students with basic theoretical notions of evolution and biological systematics. The course will enable the student to acquire both a critical approach to the study of the diversity of living matter and the propedeutic notions in the study of animal histology and anatomy and physiology
Expected learning outcomes
The student will know and understand: the main differences between eukaryotic and prokaryotic cells; the morphology and function of the main cellular components and its specializations; the basic principles of how cells interact in the context of multicellular organisms; The basic principles regulating cell cycle and the methods of cell division (mitosis and meiosis); gametogenesis and the basic principles of the early stages of embryonic development; the basic techniques for the observation and study of the cells; the basic principles of the origin of life, evolution and natural selection; basic notions on systematics, phylogenesis and classification of living organisms; basic concepts of classification and main characteristics of invertebrates and vertebrates
The student will be able to critically apply the concepts learned, during the observation of histological preparations; they will be able to describe the function of the main cellular components in a tissue context; they will be able to recognize diploid and haploid cells in the context of male and female gonads; they will be able to answer questions of medium / advanced level of cell biology; they will be able to answer basic questions about animal evolution, systematics and diversity of the animal kingdom
Course syllabus and organization

Lesson period
First semester
Teaching methods
If all the lessons could not be held to be held in person, they will be held in a "mixed form", that is, partly in the classroom and partly remotely through the Microsoft Teams or Zoom platform. In particular, for the Biology course the students of SPA will attend lesson in the classrooms two days a week, in groups. These days will be mainly dedicated to classroom and / or laboratory exercises and in-depth activities and will be organized in repeated groups depending on the capacity of the classroom.
In particular, it is expected that lectures and hands-on training will be organized as follows:
lectures: Most of the lectures will be delivered remotely through the Microsoft Teams or Zoom platform and can be followed both in synchronous according to the scheduled time and asynchronously, because they will be recorded through the same platform and made available by the teacher through the Ariel platform. In the case of seminars or lectures delivered in the classroom, the lessons could still be followed synchronously or asynchronously by those who will not be able to attend the lesson in class, through the same platforms. Where possible, the lessons will be videotaped and made available through the Ariel platform
The teacher will constantly update the students through the Ariel platform on the methods of teaching delivery.
Program and reference material: The program and the reference material of the lectures will not change. All educational support material will always be made available through the Ariel platform.
Learning assessment procedures and assessment criteria: If the situation allows it, the exam will take place in writing according to the procedures described in the section "Exam procedures". Alternatively, the exam will take place in oral form using the Microsoft Teams platform or similar. In this case, the duration of the test will be about 20 minutes and will mainly focus on assessing the student's ability to apply the knowledge acquired to analytical problems.
Course syllabus
The course is divided into 4 parts: 1) The first part concerning the general information on cell theory, characteristics of living organisms; 2) The second part concerning the individual cellular components and cellular specializations in the tissue context; 3) The third part concerning the theory of evolution, the classification and the main characteristics of some Phyla of zootechnical interest; 4) the fourth practical part is dedicated to the study of the main morphological and functional investigation methods on cells and tissues, with particular reference to cell specializations and gametogenesis

- Exercise in the microscopy laboratory (elements of cytology such as nucleus, membranes and cell junction, etc in different histological preparations, gametogenesis) (6 hours)
- Cell Culture Laboratory with particular reference to gametogenesis (2 hours)
Prerequisites for admission
No particular prerequisites are necessary; however a basic knowledge of chemistry and biochemistry is recommended.
Teaching methods
Lectures and seminars, hands on training in the tissue-culture and microscopy laboratories; Active learning using multiple choice questions during lecture, often students work in groups
Teaching Resources
- Dalle Donne I. Citologia e Istologia, EdiSES
- Solomon, Martin, Martin, Berg. Evoluzione e Biodiversità EdiSES

The material used in class will be made available through the Ariel University platform, indicating the page of the site regarding teaching.
Further indications about recommended texts for further information will be provided during the course and made available through the University platform, Ariel
Assessment methods and Criteria
The exam consists of two parts. The first part consists of a written test administered in the form of a test of 30 multiple choice questions (1 hour) on all the topics that governs access to the oral exam. The second part consists of an oral exam aimed at verifying the knowledge of the topic, the exhibition capacity, the ability to critically analyze the contents. The oral interview will be assessed out of thirty and the final grade will consider the accuracy and quality of the answers, as well as the communicative ability and the ability to adequately motivate statements, analyzes and judgments during the interview.
