申論題

5.某本植物學教科書在描述種子萌發的條件時，有下列這段文字：「As a result of desiccation, metabolism within the seed decreases to an almost imperceptible（不可察覺的）level, allowing the embryo to remain viable for long periods. Following desiccation, the seeds of some plants then enter a quiescent (“resting”) state; those of other plants become dormant.」文中提到種子萌發之前可能的二 種狀況，分別是靜止（quiescent）與休眠（dormant）。請問靜止與休眠的定義分別為何？（4分）
