【題目】( 2015四川卷)植物側(cè)芽的生長(zhǎng)受生長(zhǎng)素(IAA)及其他物質(zhì)的共同影響。有人以豌豆完整植株為對(duì)照進(jìn)行了以下實(shí)驗(yàn):

實(shí)驗(yàn)一:分組進(jìn)行去除頂芽、去頂并在切口涂抹IAA處理后,定時(shí)測(cè)定側(cè)芽長(zhǎng)度,見(jiàn)下左圖;

實(shí)驗(yàn)二:用14CO2飼喂葉片,測(cè)定去頂8h時(shí)側(cè)芽附近14C放射性強(qiáng)度和IAA含量,見(jiàn)下右圖。

(1)IAA是植物細(xì)胞之間傳遞______________的分子,頂芽合成的IAA通過(guò)_______方式向下運(yùn)輸。

(2)實(shí)驗(yàn)一中,去頂32 h時(shí)組側(cè)芽長(zhǎng)度明顯小于組,其原因____________________________。

(3)實(shí)驗(yàn)二中,14CO2進(jìn)入葉綠體后,首先能檢測(cè)到含14C的有機(jī)物是_______,該物質(zhì)被還原成糖類需要光反應(yīng)提供_____________________。a、b兩組側(cè)芽附近14C信號(hào)強(qiáng)度差異明顯,說(shuō)明去頂后往側(cè)芽分配的光合產(chǎn)物_____________________。

(4)綜合兩個(gè)實(shí)驗(yàn)的數(shù)據(jù)推測(cè),去頂8h時(shí)組和組側(cè)芽附近的IAA濃度關(guān)系為:_______(大于/小于/等于)組;去頂8h時(shí)組側(cè)芽長(zhǎng)度明顯大于組,請(qǐng)對(duì)些結(jié)果提出合理的假設(shè):____________________________。
