Phagocytosis
, meaning "cell eating," is similar to pinocytosis
, but the cell takes in solids rather than liquids. Certain kinds of white blood cells are called phagocytes because they can take in solid particles such as bacteria and cellular debris.
When a phagocyte first encounters a particle, the particle attaches to the phagocyte's cell membrane. This stimulates a portion of the membrane to project outward, surround the particle, and slowly draw it inside the cell.
The part of the membrane surrounding the particle detaches from the cell's surface, forming a vesicle that contains the particle.

3. Vacuole Formation- vacuole contains microbe
4. Digestion- vacuole merges with enzymes to destroy microbes
5. Exocytosis- microbial debris is released
--this is all occurring within a macrophage.

∙ 8y agoWhite blood cells called Macrophages (phagocytes) identify foreign antigens on bacteria and engulf and destroy them. The correct sequence of events in phagocytosis contains five events. They are, in order, chemotaxis, adherence, ingestion, digestion, and killing.

∙ 7y agoThe phagocyte adheres to the pathogen or debris., forming pseudopods that that engulf the particle which leads to the formation of a phagosome. Lysosome then fuses with the phagocytic vesicle to form a phagolysome. The lysosomal enzymes then digest the particle and leaves behind a residual body. The indigestible and residual material is then removed by the exocytosis of the vesicle.

When does Phagocytosis occur?
When Pathogen-associated molecular patterns, or PAMPS as they are referred to, attach themselves to immune cells within the body of a mammal Phagocytosis is activated in these immune cells. This then leads to the activation of NF-kB.
A defense cell engulfing a bacterium illustrates?
Phagocytosis
An organism with a cell wall would have the most difficulty doing which process?
Phagocytosis.
What are the benefits and drawbacks of phagocytosis?
The main benefit of phagocytosis is that it is a natural defense against bacterial infection. Drawbacks are that you can get coiling phagocytosis and it could destroy good bacteria.
What is the name of the process where a white blood cell engulfs a pathogen?
The process by which white blood cells engulf bacteria is termed phagocytosis. In some organisms, phagocytosis is how food is absorbed.

What are white blood cells called that engulf and destroy bacteria?
exocytosis, phagocytosis,pinocytosis, osmosis,
A defense cell engulfing a bacterium illustrates?
Phagocytosis
An organism with a cell wall would have the most difficulty doing which process?
Phagocytosis.
Where does phagocytosis happen?
Phagocytosis takes place in the blood.
Which is a method of avoiding phagocytosis?
Inducing phagocytosis.
What is the movement of particles into the cell?
The movement of large particles of solid food or whole cells into the cell is called phagocytosis. Phagocytosis occurs in three separate steps.
Phagocytosis is a form of exocytosis?
No, phagocytosis is a form of endocytosis.
An amoeba engulfs food by?
Surrounding the food with pseudopod.
What are the benefits and drawbacks of phagocytosis?
The main benefit of phagocytosis is that it is a natural defense against bacterial infection. Drawbacks are that you can get coiling phagocytosis and it could destroy good bacteria.
What is the name of the process where a white blood cell engulfs a pathogen?
The process by which white blood cells engulf bacteria is termed phagocytosis. In some organisms, phagocytosis is how food is absorbed.
What is another name for cell eating?
The word that means the same thing as cell eating is phagocytosis. The outcome is the ingestion of particulate matter, such as bacteria, from the extracellular fluid.
