          （6分）據(jù)圖回答下列問題：

          （1）據(jù)圖1，若某植物幼苗已表現(xiàn)出向光性，且測(cè)得其向光面的生長素濃度為m，則背光面生長素濃度范圍是             。
          （2）據(jù)圖1可知，除草劑滅草的原理是使雜草的生長素濃度大于       （填圖1中字母）。
          （3）在探究生長素促進(jìn)插條生根的最適濃度時(shí)，一名技術(shù)人員用幾種不同濃度生長素溶液處理插條基部，然后在沙床中培養(yǎng)，觀察生根情況。圖2為生長素促進(jìn)枝條生根的情況。請(qǐng)結(jié)合圖1判斷，在下列各項(xiàng)濃度值中，最好選用（   ）
          A．3mg·mL-1B．6 mg·mL-1C．9 mg·mL-1D．4.5 mg·mL-1
          （4）生長素的主要作用是促進(jìn)細(xì)胞縱向伸長，其作用機(jī)理如圖3所示，請(qǐng)回答下列問題：

          ①生長素作用的第一步是與細(xì)胞膜上的受體結(jié)合，形成“激素—受體復(fù)合物”，這一過程體現(xiàn)了細(xì)胞膜的              功能。
          ②實(shí)驗(yàn)發(fā)現(xiàn)，細(xì)胞在持續(xù)生長過程中，細(xì)胞壁將發(fā)生一定變化，出現(xiàn)這種現(xiàn)象的原因是由于              （填細(xì)胞器）為細(xì)胞壁添加了新的成分。
          ③此外，Ca2+ 還能激活細(xì)胞中的轉(zhuǎn)錄因子，它進(jìn)入細(xì)胞核后，能引起         酶催化mRNA的合成。
