题目:

青州蜜桃之所以香甜可口,与其生长后期的气候变化有一定的关系.下列解释中,正确的是(  )

A.后期昼夜温差大,白天光合作用强,夜晚呼吸作用弱,积累的有机物多

B.后期雨水多,生长旺盛制造的有机物多

C.后期呼吸作用强,得到的能量多

D.后期气候潮湿,桃树叶的蒸腾作用强,物质运输快

答案:

光合作用是指在叶绿体里利用光能,把二氧化碳和水合成有机物,储存能量的过程,可见光合作用必须在光下才能进行.青州地区秋季白天温度高,能促进光合作用,光合作用强,使其充分进行光合作用合成更多的糖类等有机物,同时,夜间温度低,在一定范围内,温度越低,呼吸作用越弱,减少有机物的分解,使更多的有机物得以积累,提高了青州蜜桃的甜度.因此,青州蜜桃之所以香甜可口,与其生长后期的昼夜温差大,白天光合作用强,夜晚呼吸作用弱,积累的有机物多有关.
