Question

Quizplus · Accepted Answer

Leaf abscission refers to the process of separation of leaves from stems. This process is a natural phenomenon that occurs in deciduous plants during the autumn season or under adverse environmental conditions. The separation of leaves from stems involves the differentiation of specialized cells, called abscission zones, that cause the detachment of leaves. This process allows plants to conserve energy and resources and protect themselves from harsh environmental conditions.
