29.(除注明分值外,其它每空1分,共10分)(1)类囊体薄膜色素和酶类囊体薄膜转移到叶绿体基质(2)酶、糖蛋白受体、载体蛋白、磷脂农田土壤中氮的含量往往不足以使作物高产,加之农产品源源不断地自农田生态系统输出,其中氮元素并不能都归还土壤(或人们从农田生态系统中收获粮食等农作物,会导致农田生态系统氮元素的输出比输入多,答案合理即可)(2分)(3)①a~b作物群体光合速率不变,但群体呼吸速率仍在增大(2分)②合理密植【解析】(1)叶绿体内部增大膜面积的结构是类囊体薄膜,其上分布有与光合作用有关的色素和酶;ATP在叶绿体中的类囊体薄膜上合成,在叶绿体基质中参与暗反应中C3的还原,所以其由转移途径是类囊体薄膜转移到叶绿体基质。(2)细胞膜上的含氮元素的有机物有酶、糖蛋白受体、载体蛋白、磷脂等;人们要不断地往稻田施用的氮肥,原因是农田土壤中氮的含量往往不足以使作物高产,加之农产品源源不断地自农田生态系统输出,其中氮元素并不能都归还土壤或人们从农田生态系统中收获粮食等农作物,会导致农田生态系统氮元素的输出比输入多。(3)①据图分析,在叶面积系数在a~b时,作物群体干物质积累速率最大,即作物产量最大。当叶面积系数再增大时,作物群体光合速率不变,但群体呼吸速率仍在增大,干物质积累速率在下降,产量将下降。②合理密植,控制一定的作物叶面积系数,可以获得最大的群体干物质积累速率,从而获得最大产量。
