Space 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.
空间和回转器实验表明，植物细胞结构和代谢重排取决于实验对象的分类地位和生理状态、生长阶段以及实际或模拟微重力影响的持续时间。结果表明，回转器条件仅再现了部分微重力生物学效应。现已确定，微重力下会出现各种反应：1）细胞质细胞器超微结构和钙平衡的重排；2）质膜的物理化学性质发生变化；3）酶活性常常增强。这些事件会导致细胞生长、分化加速以及衰老；同时，一些反应可被视为细胞对微重力的适应。
