Course contents
LEARNING MODULE I_PLANT BIOLOGY
INTRODUCTION: Articulations of plant biology and historical milestones. Study methodologies. Main characteristics and utility of plants. Plant nutrition (autotrophy and eterotrophy). Chemical components of living organisms (water, micronutrients, sugars,proteins and lipids).
CITOLOGY:Plant cell of vascular plants (morphology, dimension and organization).Peculiar aspects of fungal and algae cells. Structure and function of organelles. Plastids: ontogenesis and transformation of plastids. Non green plastids (leucoplast, cromoplast ed etioplast) and chloroplast (morphology, dimension, ultrastructure, pigments, plastidial genome). Algae plastids. Vacuols. Golgi. Microcorps. Cell wall and its modifications. Cell growth (mitosis, cytodieresis, cell elongation, differentiation).
HISTOLOGY AND ANATOMY of vascular plants: Kind of tissue and their functions. Root, stem, leaf, flower, fruits anatomy and organography. Primary structure of stem and root.
PHYSIOLOGY: Carbon cycle. Photosynthetic pigments (chemical structure, functions and light absorbance). Photosynthetic unit. Carbon organication: light and dark photosynthetic phase; C3 and C4 cycles; CAM. Photorespiration. Nitrogen cycle. Noitrogen organication. Secondary metabolites (their function in plant and main utilizations by humans). Water absorption and transport.
RIPRODUCTION vascular plants. Embriogenesis. Seed and seed germination. Vegetative propagation.
MORPHOGENESIS: Differentiation, growth and development. Programmed cell death. Plant hormons. In vitro coltures. Biotechnologies and plant.
LEARNING MODULE II_BIODIVERSITY: Origin and evolutionary history of life on Earth. Taxonomy and systematics. Phylogenetic classification. Monophyletic, paraphyletic, and polyphyletic group (clade). Cyanoprokaryotes (and Prochlorophytes). Endosymbiosis. Characterization and life cycles of the main groups of plant-like organisms (photoautotrophs) and fungi. Overview of algae and algal groups believed to be ancestors of terrestrial plants. Green algae. Lichens. Red algae. Dinoflagellates. Algal blooms. Diatoms. Brown algae. Bryophytes. Pteridophytes. Gymnosperms. Angiosperms: origin, basal groups, central groups. Insights on Magnoliaceae, Asteraceae, Rosaceae, Apiaceae, Lamiaceae, Fabaceae, Brassicaceae, Liliaceae, Solanaceae, Poaceae.

Teaching methods
Oral presentations preliminary to the practical laboratories by observations at the microscope.
In consideration of the type of activity and the teaching methods adopted, the attendance of this training activity requires the prior participation of all students in the training modules 1 and 2 on safety in the study places, in e-learning mode.
Assessment methods
The exam, combined for the two modules, consists of a first written part and an oral part.
The written part consists of a test with 2 questions, one related to the module of plant diversity and one related to the module of plant biology (open-ended questions with recognition of a microscopic image related to plant tissues and organs).
It is necessary to pass the test to be admitted to the oral examination, that will consist in the recognition of a microscope image and, possibly, in the evaluation of a report on the laboratory part of the course, as well as some questions on the topics addressed during the lectures of the course. The photoautotroph diversity part consists in the discussion of the open answer to the question in the written test supplemented by another question on a topic covered in the lectures of the module.
The final mark results from the overall evaluation of the different parts. If a fundamental topic will be not sufficiently known, the entire examination will be negatively evaluated.
