___________________ is also called cell drinking and is an example of an endocytic process.

Verified step by step guidance

1. Identify the term that describes the process of a cell taking in liquid from the surrounding environment.
2. Recall that this process involves the engulfing of extracellular fluid, including dissolved solutes, into small vesicles.
3. Understand that this process is a type of endocytosis, which is a broader category of cellular processes used to internalize substances from the external environment.
4. Recognize that this specific type of endocytosis is distinct from phagocytosis, which involves the engulfing of larger particles or cells.
5. Conclude that the term for this process, which is also known as 'cell drinking,' is pinocytosis.

Key Concepts

Endocytosis

Endocytosis is a cellular process in which substances are brought into the cell by engulfing them in a membrane-bound vesicle. This process is crucial for nutrient uptake, signaling, and maintaining cellular homeostasis. It includes various forms, such as phagocytosis and pinocytosis, which differ in the size and type of material being internalized.

Pinocytosis

Pinocytosis, often referred to as 'cell drinking,' is a specific type of endocytosis where the cell engulfs extracellular fluid along with dissolved solutes. This process allows cells to sample their environment and take in small molecules and nutrients. It is a non-specific mechanism, meaning it does not target specific substances.

Vesicle Formation

Vesicle formation is a critical step in endocytosis, where the cell membrane invaginates to form a pocket that eventually pinches off to create a vesicle. This vesicle then transports the ingested material into the cell. The dynamics of vesicle formation are essential for understanding how cells regulate their internal environment and respond to external stimuli.
