During the maturation process of an ovule, the internal walls of the embryo sac becomes gradually thinner from the poles to the central cell. The thinning process results in an association of two plasma membranes with no polysaccharide structure betwen them. The presence of one disymmetrical ER cistern along the walls during the thinning process permits to anticipate a turn-over of carbohydrates
