Learning outcomes

This course aims to give to the student the basic knowledge about plant cytology, histology and organography and some basic knowledge of plant physiology. In particular, the student will be able to recognise cytological and anatomical structures and plant morphology.


Course contents

Cytology - Life origins. Prokaryotic and eukaryotic organisms. Cell structure of prokaryotics. Eubacteria and cyanobacteria. Cell structure of eukaryotic organisms. The plant cell. Plant cell wall chemical structure (cellulose, hemicellulose, pectic substances and glycoproteins). Primary and secondary cell wall; modifications of the secondary cell wall. Primary and secondary metabolism. Vacuole: structure, formation, differentiation and functions. Plastids. Chloroplast structure. Chemical structure and functions of starch. Leucoplasts and chromoplasts. Theories on the origin of plastids.

Morphological organization of plants - Outline of sistematics in plants

Histology – Primary and secondary meristems. Parenchyma. Epidermal tissues (stomata and tricomes). Mechanical tissues (collenchyma and schlerenchyma). Transport tissues (xylem and phloem). Secretory cells and tissues. Vascular bundles

Anatomy – Morphology and anatomy of the stem, root and leaf and their morphological modifications. Primary and secondary structures. Structure of wood. Structure of Spermatophytes (Gymosperm and Angiosperm both Monocots and Dicots). Flower, fruit and plant reproduction.

Elements of Plant Physiology - Photoautotrophy and chemioautotrophy. Autotrophy and heretrotrophy: symbiosis and parasitism. Photosynthesis: pigments, light and dark phase. C3, C4 and CAM plants. Photorespiration. Nitrogen metabolism and cycle. Mineral nutrition. Plant hormones: auxins, cytokinins, gibberellins, abscissic acid, ethylene, brassinosteroids, jasmonates, polyamines.
