Answer:
The amoeba is a single-celled organism that can change its shape.
Explanation:
- Ponds, lakes, and slow-moving rivers are common places where they can be found.
- These unicellular organisms can sometimes find their way into the human body and cause a variety of ailments.
Structure of Amoeba:
- Pseudopodia are projections created when the cytoplasm pushes the plasma membrane outward or inward, resulting in blunt, finger-like projections.
- Because many pseudopodia can exist at the same time, the shape of the pseudopod quickly changes.
- The cytoplasm, plasma membrane, and nucleus are the three main components of an amoeba's structure.
- The cytoplasm is divided into two layers: the ectoplasm on the outside and the endoplasm on the inside.
- The plasma membrane is a double-layered membrane made up of protein and lipid molecules that is exceedingly thin.
- Other cellular organelles seen in amoeba include a contractile vacuole, mitochondria, the Golgi apparatus, and fat globules.
- The phagocytosis or pinocytosis processes are used by amoebae to consume food.
- Asexual reproduction, such as binary fission, is used to reproduce.
- A typical amoeba has a lifespan of two days, but because it performs binary fission, the resultant daughter cells are identical to the parent cell, and amoebas are technically immortal.
- An amoeba may essentially change itself into a protective ball called a microbial cyst when living conditions aren't perfect.
- It can revert to its trophozoite stage when living conditions improve, allowing it to resume feeding.
