34.(13分)根据图示装置(其中NaHCO3溶液可为植物提供CO2),利用学过的知识,简要回答下列问题:

(1)若将这个装置用来探究CO2是光合作用的原料,则还应该再增加一个装置,做法是其他条件同这个装置                       。若用于探究SO2对植物生长的影响,则烧杯中的NaHCO3溶液应换成                    

(2)若将这个装置用来探究元素X是否为植物的必需矿质元素,则还应该增加一个对照装置,做法是                                      。为确保实验获得成功,则还应该适时地向培养液中通入空气,目的是            。若研究的化学元素是镁元素,当其缺乏时,植株的    (老、幼)叶首先表现出症状,原因是                     

(3)若参照此装置,只去掉其中大NaHCO3溶液,设置同样的两套装置,其中一套装置培养一株菠菜(C3植物),另一套装置培养一株苋菜(C4植物),每天都照光12h。一星期后,菠菜死亡,而苋菜依旧存活,其原因最可能是
