AbstractSpace and clinostatic experiments revealed that plant cell structure and metabolism rearrangements depend on taxonomical position and physiological state of objects, growth phase and real or simulated microgravity influence duration. It was shown that clinostat conditions reproduce only a part of microgravity biological effects. It is established that various responses occur in microgravity: 1) rearrangements of cytoplasmic organelles ultrastructure and calcium balance; 2) physical-chemical properties of the plasmalemma are changed; 3) enzymes activity is often enhanced. These events provoke the acceleration of growth and differentiation of cells and their aging as a result; at the same time some responses can be considered as cell adaptation to microgravity.
