Question

Why do leaves or fruits fall on the ground after breaking from the tree​

Answer 1

Explanation:

Detachment can occur when layers of parenchyma cells secrete cell wall enzymes to self-digest the middle lamella, which holds the cell walls together at the abscission zone. This causes the cells of the abscission zone to break apart and the leaf or other plant part to fall off.
