The modern concepts on the primary cell walls of angiosperm plants

The modern view on polysaccharide composition of the primary cell wall of angiosperm plants was considered, and five classes of structural proteins were characterized. The model which shows location of enzyme complex synthesizing cellulose, as well as structural model of primary cell walls of the most flowering plants were presented. Besides, there were shown cell wall reactions to environmental factors which have contradictory character and have to be deeply and thoroughly analyzed.
