Answer #1

Answer: Pseudopodium

Reason: The micrographical image of the organism shows clearly that there are no cellular extensions or appendages present in the organism directly involved in motility such as cilia, flagella etc. This organism moves by the means of formation of cellular cytoplasmic extensions like structures called the false feet or pseudopodia. These pseudopodia are not clear physical structures for movement and locomotion but help in motility by extending the cytoplasmic membrane forward and pulling the cell in forward direction. This type of motion is normally seen in simple organisms like Amoeba.

    4) Studying the motility of the pathogenic bacteria Listeria and Shigella, which cause food poisoning and dysentery, respectively, significantly advanced our understanding of actin polymerization. These bacteria escape immune surveillance by entering one cell’s cytoplasm and then spreading from cell to cell without exposing themselves to the outside environment. They harness actin polymerization to push themselves against the plasma membrane, generating a membrane protrusion that is engulfed by a neighboring cell, giving them direct access to that cell’s cytoplasm. The...
