In Lithuania project “Standardized assessment of student achievement and self-assessment tool for schools of general education development” (Phase I) has been carried out for three years. It is the first time testing specialists’, specialists’ in didactics and teacher’s experience have been merged and statistical and expert information have been systematised and generalized. Standardized grade 8 math programme was created, in which for the first time three students’ achievement levels descriptions and illustrated tasks’ examples are presented. Creation of the programme and programme’s presentation to mathematics community gave rise to many discussions about the different students’ achievement levels abilities and reasons for it. Extra-large ability differences emerged in the field of geometry, which encouraged the authors to go deep into the problems of this area. Authors took advantage of the project database and completed geometry tasks and their solutions deep analysis. This article presents the summarized results of the study.

It was found that the growth curve of the rape embryo axis is of triple sigmoid type. Embryo growth occurs in 3 phases corresponding to 3 different periods of development. Phase I includes growth of the apical cell up to it's division into two layers of octants. Phase II comprises the increase of the spherical proembryo to the change of its symmetry from radial to bilateral. Phase III includes, growth of the embryo from the heart stage up to the end of embryogenesis. In each phase the relative growth rate increases drastically and then diminishes. The differences in growth intensity during the same phase are several-fold. The growth intensity maximum of the embryo axis occurs in phase II. The phasic growth intensity maxima occur: in phase I during apical cell elongation, :before its division, and in phases II and III in the periods of cell division ;growth in globular and torpedo-shaped -shaped embryos.
