Becoz in animal cells, cell wall is absent. hence plasma membrane is in direct contact with the external environment. the plasma membrane is flexible in nature and helps in swallowing up of food and foreign particles by active transport. plants have rigid cell wall and cannot perform endocytosis.

Answer:
Endocytosis is swallowing up of food and other substances from external medium by the plasma membrane. This is possible only when plasma membrane is in direct contact with external medium. It occurs only in animal cells. In plant cells, a cell wall is present on the plasma membrane. Therefore, their plasma membrane cannot perform endocytosis.
