A.a神经元兴奋时，兴奋部位Na通道只容许与自身通道的直径和形状相适配、大小和电荷相适宜的Na通过，故A项错误B.一个神经元轴突末梢与另一个神经元或其他细胞相接触的部位，都可称为突触，故图中所示部分共有7个突触，故B项错误。C.由“肌肉被重物牵拉引起肌梭兴奋，通过α神经纤维和Y神经纤维导致梭外、梭内肌纤维收缩”可知，肌梭既能感受兴奋，也能传递兴奋。从反射弧结构组成的角度分析，肌梭既是感受器，也是效应器；据图可知，A神经元上有神经节，因此，A神经元属于传入神经元；由于Y神经元兴奋引起梭内肌纤维收缩，从而提起重物，且图中突触释放的神经递质均为兴奋性递质，因此，Y神经元兴奋，最终会使骨骼肌收缩的力量增强。故C项正确。D.根据图2，只有当刺激达到一定值(S)时，膜电位才发生改变，神经元才开始兴奋；且S增强到S的过程中，兴奋强度不随刺激强度增强而增强。动作电位过程中膜电位的去极化是由钠通道开放所致，因此刺激引起膜去极化，只是使膜电位从静息电位达到阈电位水，而与动作电位的最终水无关。因此，阈刺激与任何强度的阈上刺激引起的动作电位水是相同的，称之为“全或无”。故D项正确。20.ACA.少数植物的种子（如烟草和莴苣）需要在有光的条件下才能萌发，但是此时的种子没有叶绿素，不能进行光合作用；故A项说法错误。B.树木年轮的形成是树木形成层受外界季节变化产生周期性生长的结果。春夏季温度较高，细胞分裂快，细胞体积大，形成的年轮颜色较浅；秋冬季温度较低，细胞分裂慢，细胞体积小，形成的年轮颜色较深；故B项说法正确。C.植物的根、茎中具有感受重力的物质和细胞，可以将重力信号转换成运输生长素的信号；故C项说法错误。D.在长期进化的过程中，某些植物形成了需要低温来诱导其开花的特性，一般认为，在春化作用过程中，植物感受低温的部位是茎端分生组织或某些能进行细胞分裂的部位，可能诱导产生了赤霉素；故D项说法正确。三、非选择题（共55分）21.（10分，除标注外，每空1分)(1)下丘脑含GLUT4的囊泡进行细胞间信息交流和控制物质进出细胞(2分，答对1点得1分)甲状腺和肾上腺（答全才得分）(2)内质网蔗糖(3)①中心②核孔③物理信息、化学信息和行为（答全才给分）22.（12分，除标注外，每空1分)(1)增加光照强度升高温度或CO2浓度(2)光光反应速率比暗反应快，增加暗期可以促进ADP(和P)和NADP+的再生，从而影响光合作用速率(2分)低光照强度（或叶绿素含量低）(3)①C3植物C3植物CO2饱和点更高，能够固定更多的CO2(2分)【高三生物学·参考答案第7页（共8页）】·25-129C·
