高考生物重点易错题
(每日一练)高考生物重点易错题单选题1、下列关于动植物体内物质运输的说法错误的是（）A．胚芽鞘尖端的生长素极性运输导致其向光弯曲生长B．甲状腺激素经体液运输可作用于下丘脑内分泌细胞C．神经递质经突触间隙的组织液运输后能作用于肌肉或腺体D．唾液淀粉酶由内质网→高尔基体→细胞膜以囊泡形式运输答案：A解析：向光生长的原因是由于尖端在单侧光的刺激下，生长素发生了横向运输，导致背光侧生长素含量多于向光侧，使背光侧生长速度快于向光侧，A错误；甲状腺激素的靶细胞为全身的细胞，甲状腺激素可通过反馈调节作用于下丘脑的内分泌细胞，B正确；效应器是由传出神经末梢及其支配的肌肉或腺体构成的，神经肌肉接点类似突触结构，细胞之间的液体为组织液，故神经递质经突触间隙的组织液运输后能作用于肌肉或腺体，C 正确；唾液淀粉酶为分泌蛋白，由附着在内质网上的核糖体合成，经过内质网的加工后，由内质网形成囊泡运输到高尔基体，经过高尔基体的进一步加工、分类和包装后，由高尔基体形成的囊泡包裹运输到细胞膜，通过胞吐的方式分泌到细胞外，故唾液淀粉酶由内质网→高尔基体→细胞膜以囊泡形式运输，D正确。
所以答案是：A。
生物向性运动的6个警示点：①生长素的产生部位——胚芽鞘尖端。
②发挥作用的部位——尖端下面一段。
③感光部位——胚芽鞘尖端。
④生长素的作用——促进生长。
⑤弯曲生长的原因——生长素分布不均匀，导致生长不均匀。
⑥引起生长素分布不均匀的原因——单侧光照、地心引力等。
2、以测定的CO2吸收量与释放量为指标，研究温度对某绿色植物光合作用与细胞呼吸的影响，结果如图甲所示，下列分析正确的是（）A．光照相同时间，在20℃条件下植物积累的有机物的量最多B．光照相同时间，35℃时光合作用制造的有机物的量与30℃相等C．如果该植物原重Xkg，置于暗处4h后重（X-1）kg，然后光照4h后重（X+2）kg，则总光合速率为3/4kg．h D．若将乙装置中NaHCO3溶液换成蒸馏水，则在黑暗条件下可测得B曲线答案：B解析：A、图甲中的曲线A表示净光合速率随温度的变化，因此有机物积累最多即净光合速率最大时的温度是25℃，A错误；B、在光照时间相同的情况下，30℃时光合作用的总量为3.50mg／h（净合成量）＋3.00mg／h（呼吸消耗量）＝6.50mg／h，35℃时光合作用的总量为3.00mg／h（净合成量）＋3.50mg／h（呼吸消耗量）＝6.50mg／h，二者相同，B正确；C、该植物原重Xg，置于暗处4h后重（X-1）g，说明4h的呼吸消耗是1g，然后光照4h后重（X＋2）g，说明4h的净光合积累是3g，则总光合速率为则总光合速率为（1+3）g/4h=1g/h，C错误；D、将乙装置中 NaHCO3溶液换成氢氧化钠溶液，则在黑暗条件下，植物只进行呼吸作用，不进行光合作用，氢氧化钠溶液可吸收呼吸作用产生的二氧化碳，通过水滴移动的位置可测得B曲线，D错误。
