2024年9月19日 · Here’s an explanation of the key components of an amoeba’s structure: The cell membrane encloses the amoeba, providing shape and protection. It is flexible and allows the amoeba to change shape as it moves and engulfs food particles. The cytoplasm is the gel-like substance within the cell membrane.

2024年1月9日 · Amoeba is a colourless uni-nuclear or single-cell organism that can change its shape with the pseudopodia. Pseudopodia are generally an arm-like temporary structure of cytoplasm that consists of a cell membrane.
