：细胞凋亡是动物细胞的一个特征，它解释了植物细胞程序性死亡的某些方面。植物和动物细胞发育的差异要求重新审视概念，以表明植物细胞是如何进化的，需要在分生组织的生长习性、生命周期和世代交替中消除细胞。这一主题的中心是有丝分裂、减数分裂、无融合生殖及其相关的有性和无性生殖过程的分裂周期的调节。细胞凋亡依赖于调控细胞周期和凋亡途径的基因的协调表达，从而发生不可逆转的胞核和胞质消除。细胞降解产物被回收以维持适应、生存、结构功能和个体发育。细胞壁通常被保留，并进一步分化或消除。为了比较植物和动物细胞之间的差异，提出了一个包含细胞分裂周期中检查点的易导致细胞凋亡的因素模型。
: Apoptosis is a feature of animal cells that explains some aspects of programmed cell death in plants. Differences between plant and animal cell development require that concepts be reexamined to signify how plant cells have evolved the need for cell elimination in the meristematic growth habit, life cycle, and alternation of generations. Central to this theme is the regulation of divisional cycles for mitosis, meiosis, apomeiosis, and their related sexual and asexual reproductive processes. Apoptosis depends on the coordinated expression of genes regulating divisional cycles and apoptotic pathways so that irreversible nuclear and cytoplasmic elimination occurs. Cellular degradation products are salvaged to sustain adaptation, viability, structural function, and ontogeny. The cell wall is usually retained and further differentiated or eliminated. A model of factors predisposing apoptosis and comprising checkpoints in cell divisional cycles is presented for comparisons among plant and animal cells.
