Detailed explanation-1: -Pinocytosis (“pino” means “to drink”) is a process by which the cell takes in the fluids along with dissolved small molecules. In this process, the cell membrane folds and creates small pockets and captures the cellular fluid and dissolved substances.

Detailed explanation-2: -Pinocytosis Is an Active Transport Mechanism for Reabsorption of Proteins. Some parts of the tubule, especially the proximal tubule, reabsorb large molecules such as proteins viapinocytosis, a type ofendocytosis.

Detailed explanation-3: -Answer and Explanation: Phagocytosis, pinocytosis, and exocytosis are all examples of active transport. Active transport is a type of transport that uses energy. During phagocytosis, cells use their membrane to take in large molecules from the external environment.

Detailed explanation-4: -Endocytosis takes particles into the cell that are too large to passively cross the cell membrane. Phagocytosis is the taking in of large food particles, while pinocytosis takes in liquid particles. Receptor-mediated endocytosis uses special receptor proteins to help carry large particles across the cell membrane.

Detailed explanation-5: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated. Illustration of osmosis. A beaker is divided in half by a semi-permeable membrane.
