Question

* List the characteristic features of amoeba

Answer 1

Amoeba

1. Amoeba is a unicellular organism that has the ability to change its shape.
2. They are usually found in water bodies such as ponds, lakes, and slow-moving rivers.

Structure of Amoeba

1. Movement occurs through the use of pseudopodia, where the cytoplasm pushes the plasma membrane outward or inward, creating blunt, finger-like projections.
2. There can be multiple pseudopodia at one particular instance, hence, its shape rapidly changes.
3. Structure of Amoeba primarily encompasses 3 parts – the cytoplasm, plasma membrane and the nucleus.
4. The cytoplasm can be differentiated into 2 layers – the outer ectoplasm and the inner endoplasm.
5. The plasma membrane is a very thin, double-layered membrane composed of protein and lipid molecules.
