Abstract: 
The comparative analysis of structural parameters of mesophyll ceils and C02-assimilation rate for the control and cllnorotated plants revealed the essential alterations in growth and development of Arabidopsis. This influence resulted in increase of mesophyll cells volume and intercellular space, in decrease of starch inclusion in the mesophyll subepidermal chloroplasts, which may be partialy due to their higher respiration rates and growth activation of experimental plants.
