6、SUITANGYANLIAN隨堂演練ZHONGNAN JVJIAO重難聚焦ZHISHI SHULI知識梳理一二二、細(xì)胞分化的基礎(chǔ)1.全能性的概念:細(xì)胞的全能性是指生物體已經(jīng)分化的細(xì)胞仍具有發(fā)育成完整新個體的潛能。植物細(xì)胞具有全能性,動物體細(xì)胞的細(xì)胞核具有全能性。2.細(xì)胞具有全能性的原因受精卵中蘊(yùn)含著個體發(fā)育全部過程的“藍(lán)圖”完整的基因組,所以在發(fā)育潛能上受精卵屬于“全能”細(xì)胞。高等生物體所有不同類型的體細(xì)胞,都是由受精卵細(xì)胞分裂和分化而來的,所以生物體的每個體細(xì)胞都具有保持該物種遺傳性的全套遺傳物質(zhì)。3.細(xì)胞的全能性是細(xì)胞分化的基礎(chǔ),是植物組織培養(yǎng)技術(shù)的理論依據(jù),在理論和實(shí)踐上具有重大意義。M
