Question

Give a simple explanation of how an Amoeba moves.

Answer 1

Amoeba:

1. Amoeba is unicellular organisms that are capable of changing shape.
2. They are commonly found in reservoirs such as ponds, lakes, and slow-moving rivers.

Mechanism of Amoeba:

1. Phagocytosis is a mechanism in which an amoeba consumes the food it intends to ingest.
2. Holozoic nutrition describes the process by which an amoeba consumes food.
3. It causes food material to be consumed, digested, and ejected.
4. Amoeba constantly changes its shape and position.
5. It pushes out one or more finger-like projections, called pseudopodia or false feet for movement and capturing food.
6. The Amoeba's locomotion mechanism is as follows:

• Plasmasol is moving towards the pseudopodia while the plasma gel is contracting.
• Due to the turgidity of the semipermeable membrane, plasma gel expands, resulting in pseudopodia.
• Plasmasol gelation causes pseudopodia to grow bigger.
• Adherence to food particles.
