Question

How does the shape of an amoeba differ from the shape of a paramecium?

Answer 1

Amoeba is a single-celled protozoan that moves with the help of pseudopodia while Paramecium is a freshwater animal which moves by beating the cilia.

Complete answer:
Amoeba and paramecium are both single-celled eukaryotes belonging to the Protista Kingdom. They are heterotrophs, which possess special feeding processes. In its single-celled body, the Amoeba cell comprises a membrane-bound nucleus, food vacuoles and contractile vacuoles. Amoeba’s cell division occurs by division of the cytoplasm . Amoeba allows the formation of pseudopodia to proceed slowly. A false foot is also called a pseudopodium.

Another unicellular eukaryote that lives in freshwater and rotting organic matter is Paramecium. It has a shape similar to a slipper with a length of 0.3 mm. There are cilia covering the outer surface of the paramecium. A large macronucleus and a micronucleus with food vacuole and contractile vacuoles contain a paramecium cell. Under favorable conditions, Paramecium asexually reproduces by binary fission.

Note: 1.Reproduction takes place by binary fission in both amoeba and paramecium.
2.Water moves in them by osmosis.
3.They synthesize their protoplasm using amino acids.
4.They do respiration by diffusion.
5.Under unfavourable conditions amoeba forms spores for reproduction.
