What is the difference between pinocytosis and phagocytosis?
Pinocytosis is the process where substance is directly ingested as it is in dissolved form and ready for cellular absorption. It is done by the process of invagination.
Phagocytosis is the process where particles are broken down into simpler substance with the help of enzymes for absorption. It is mainly done by pseudopodia.
