Which of the following statements accurately describes the process of leaf abscission?
A: The abscission layer consists of fiber cells that strengthen the connection between the leaf and the stem.
B: An aging leaf increases auxin production, making the abscission layer less sensitive to ethylene.
C: The primary function of the protective scar formed by cork is to attract animals for seed dispersal.
D: Ethylene's influence on the abscission layer leads to the production of enzymes that digest cell wall components.
Explanation
The text states: 'As the influence of ethylene on the abscission layer prevails, the cells produce enzymes that digest the cellulose and other components of cell walls.'
