點解2005年Q53係B唔係D？

[@workhardplaycards]

因為頭幾日植物未有葉，呼吸作用respiration會快過光合作用photosynthesis，所以乾質量Dry mass會先下降。

係咪寫分解同水解都得

HKCEE2006 (ii)個題有冇答案

[@workhardplaycards]

唔知點解黑左…好奇怪
答案：
The average dry mass of the seedlings grown in daylight increases from day 12 to day 18, while that of seedlings grown in darkness continues to decrease (1)
because under daylight, the seedlings have developed green leaves (1)
for photosynthesis (1)
The rate of food production is faster than the rate of food consumption (1)
resulting a net gain in dry mass
在 12 至 18 日，在日照下生長的幼苗乾質量增加，
但在黑暗中的幼苗乾質量則持續減少 (1)
因爲在日照下，幼苗已長出葉子 (1)
進行光合作用 (1)
當食物生產速率高於速率食物消耗速率 (1)
乾質量因而有淨增長
