Training objectives
- Plant biology is a discipline of biology that studies the morphology of plant organisms also in relation to the environment in which they live.
The main objective of the course is to provide the student who is about to study biology with the basic theoretical and practical knowledge of cytology, histology and organography of tracheophytes, with particular reference to agricultural plants, as well as some basic notions of plant physiology . Prerequisites
- No prerequisites are foreseen, however knowledge of the basics of biology, of the elements of chemistry and physics useful for the introduction to the study of plant biology are required.
Course programme
- Course content:
Introduction to the study of plant biology. Importance of plants for humans and the environment. Importance of agricultural plants.
- Plant cytology. Difference between animal cell and plant cell. Autotrophic and heterotrophic. Difference between prokaryotes and eukaryotes. Animal and plant organisms: analogies and differences. Notes on the chemical composition of living matter. The eukaryotic plant cell. Plastids. The vacuole and its contents. The cell wall and its modifications.
- Plant histology. Cell and energetic. Thallophytes and cormophytes. Real fabrics and pseudo-fabrics. Meristematic fabrics. Parenchymal fabrics. Mechanical fabrics. Conduction fabrics. Integumental tissues. Secretory tissues.
- Reproduction in vegetables. Reproduction in vegetables. Types of vegetative reproduction. Sporulation and sporogony. Sexual reproduction. Ontogenetic cycles. The flower of the angiosperms. Evolution of the flower. Androecium. Gynoecium. Double fertilization. The fruit.
- Plant organography. From seed to seedling. The sprout. Types of branching. The gem. The stem in the apex-base sense. Stem cross section. Stem cross section in secondary structure. The root. Cross section of the root. The leaf.
- The main families of agricultural plants.
- Plant physiology: the absorption and transport of solutions. Some basis on plant hormones. Photosynthesis. Didactic methods
- Frontal lectures, supported by streaming links, for working students or those unable to attend in-person classes.
Learning assessment procedures
- The objective of the exam consists in verifying the level of knowledge and in-depth study of the topics of the course program and the reasoning ability developed by the student. The evaluation is expressed in thirtieths (minimum score 18).
The examination method is generally written in computer mode, however the possibility of oral tests is not excluded.
The test consists of questions concerning each part of the program (plant cytology, histology, reproduction, organography, agricultural plants, notions of plant physiology). For multiple choice test, score 1 for correct answers; score 0 for incorrect answers. For open questions, the maximum score for each answer is 5, the minimum score is 3.
The exam allows you to ascertain the achievement of the objectives in terms of knowledge and understanding.
The exam also aims to understand communication skills in relation to the use of specific language. Reference texts
