Phagocytosis
When a cell engulfs a particle, it is called phagocytosis. Certain white blood cells phagocytize and digest infectious particles like bacteria to kill them.
Large molecules enter a cell through a process called endocytosis. This involves the cell engulfing the molecule by forming a vesicle around it, which is then brought into the cell. There are different types of endocytosis, such as phagocytosis (engulfing solid particles) and pinocytosis (engulfing liquid particles).
Phagocytosis Added: A more precise answer here is that this is a form of endocytosis. Phagocytosis usually is particle engulfing without the vesicle, necessarily.
Phagocytosis is called 'cell eating' because it is a process in which a cell engulfs and digests particles or other cells by forming a vesicle around them. This process is similar to a cell 'feeding' on external material by actively engulfing it.
Endocytosis is a cellular process in which cells absorb molecules (such as proteins) by engulfing them into vesicles formed from the cell membrane. There are different types of endocytosis such as phagocytosis (engulfing solid particles), pinocytosis (engulfing liquid components), and receptor-mediated endocytosis (specific molecules are taken up after binding to receptors on the cell surface). Once the vesicle is formed, it moves to the interior of the cell for further processing.

A bacterium has a cell membrane, not a cell wall.

Bacterium is a prokariyote.Others are eukariyotic cells.

Bacterium has prokaryotic cells- cells that have no membrane-bounded organells.
exocytosis- particles are expelled from a cell or body- vessicles (sacs) containing the particles fuse with the cell membrane and the contents are expelled endocytosis- particles are induced within a cell- cell membrane forms around them and takes them in: * pinocytosis: engulfing of liquid particles * phagocytosis: engulfing of solid particles (such as a white blood cell engulfing a pathogen)

In scientific terms, "engulfing" refers to the process by which a cell or organism surrounds and internalizes a substance, typically through mechanisms like phagocytosis or endocytosis. This process allows cells to ingest larger particles, such as pathogens or debris, and is crucial for immune responses and nutrient uptake. Engulfing is an essential function in various biological contexts, including cellular maintenance and the immune system's defense against infections.
