The adaptive structural and functional strategies enable plants to survive in variable biotopes. The intensity of some parameters of abioticfactors can be estimated from the environment on the basis of anatomic studies. In this research paper there are histo-anatomical studiesof the leaf blades and stems of 10 angiosperm species which have populations growing in both open and shaded places from mountainousbiotopes in the Ciuc-Basin¸ with the application of methods for making microscopical preparations. The qualitative evaluation of thehisto-anatomical properties was combined with determination of stomata density and biometric data. Up to the present, there have beenno histo-anatomical studies in plants distributed in these areas. The studied species possess histological structures adapted to utilizingmore efficiently the light energy and humidity accessible to plants in their habitats. The structural adaptations to illumination conditionsof the studied species can be distinguished in the structure, types and development rate of the assimilatory and mechanic tissues.
