Why is endocytosis found in animals only?

(N/A) Endocytosis is the process by which cells engulf materials from their surroundings by forming vesicles from the plasma membrane.
In animal cells,the plasma membrane is the outermost boundary because a rigid cell wall is absent.
This flexibility allows the plasma membrane to fold inward and engulf external substances.
In contrast,plant cells possess a rigid,protective cell wall outside the plasma membrane,which prevents the membrane from invaginating or engulfing large particles,thus making endocytosis impossible in plant cells.
