Question

what is phagocytosis in amoeba ? Does any other organisms follow phagocytosis?
​

Answer 1

$\LARGE{ \underline{ \bf{ \purple{Required \: answer}}}}$

The Amoeba ingests its prey as its food by the process of Phagocytosis. When it comes in contact with food particles or any smaller organism, it forms a Pseudopodia or False feet which engulf the prey by forming a cup around it. This is how Phagocytosis occurs.

✹ What happens after Phagocytosis?

• The tips of Pseudopodia touches each other and capture the food inside a food vacuole.
• This acts as a temporary stomach where digestive enzymes and juices are secreted.
• This is absorbed and assimilated into the cytoplasm evenly and this increases the size of Amoeba.
• Here, the digested food was absorbed and now it will be used for the production of energy, helps in repair and initiate growth.
• The left over undigested food is then thrown out of the body of the Amoeba.

✹ Another cell that show Phagocytosis?

Likewise Amoeba, White blood cells also show phagocytosis during the protection of the body from pathogens. When White blood cells detect foreign particles & germs, it engulf it by the process of phagocytosis and forms a phagosome. This destroy the content by acidifying. Later, Lysosome dissolves and destroy the harmful contents.

Answer 2

${ \sf{ \underline {\blue {What \: is \: Phagocytosis \: in \: amoeba:-}}}}$

"Phagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it. "

The process of phagocytosis often happens when the cell is trying to destroy something, like a virus or an infected cell, and is often used by immune system cells.

${ \mathfrak{ Steps \: involves \: in \: Phagocytosis:-}}$

✍Activation of the Phagocyte.

✍ Chemotaxis of Phagocytes (for wandering macrophages, neutrophils, and eosinophils) .

✍Attachment of the Phagocyte to the Microbe or Cell.

✍ Ingestion of the Microbe or Cell by the Phagocyte.

${ \sf{ \underline{ \blue{Other \: cell \: that \: follow \: Phagocytosis:-}}}}$

◐White blood cell also follow phagocytosis.

◐They bind to pathogens and internalise them in a phagosome, which acidifies and fuses with lysosomes in order to destroy the contents.
