INTRODUCTION Characteristic of the living. Plants and animals. Notion of vegetal organism. Classification of vegetals : Thallophyte and Cormophyte. Importance of vegetals.

CYTOLOGY Cellular theory. Prokaryotic and eukaryotic cell. Vegetal eukaryotic cell : shapes, sizes and compartmentalizations. Meristematic cell and adult cell. Cell wall in Plants : formation, growth, chemical composition, structure, functions; middle lamella, primary wall, secondary wall; secondary mo difications of wall; bordered pits, poro channel and plasmodesma; phragmoplast, symplast and apoplast. Cell wall in Algaes and Mushrooms. System of vacuoles : origin, development, structure and functions; tonoplast and cell sap; including solids and products of secondary metabolism. Plastids : origin, development, structure, types and functions. Chloroplasts, Chromoplasts, Leucoplasts, Gerontoplasts. Primary and secondary starch. Starches of F.U.I. Cellular components of pharmaceutical interest and diagnostic character.

HISTOLOGY Colonies, pseudo-tissues, tissues. Meristematic tissues (primary and secondary); tegmenic tissues (rhizoderm, epidermis, endoderm, esoderm, cork); Stomas and Stomatic Index of F.U.I.; parenchymatic tissues (chlorophyllian parenchyma, reserve parenchyma, conducting parenchyma, air parenchyma, water parenchyma); mechanical tissues (collenchyma and sclerenchyma); conducting tissues (xylem and phloem). Histological diagnostic characters.

ORGANOGRAPHY The whole plant; herbaceous planta, woody plants (trees and shrubs); vital cycle of plants. Root : functions and external organization; anatomy : meristematic zone, primary structure zone and secondary structure zone; metemorphosis of root.
