Answer:
The cell of amoeba is shaped differently than the classical round or boxy shape seen in textbooks.
Explanation:
Amoebas are unicellular organisms i.e consisting of a single cell. The amoebic cell can change its shape due to pseudopods. Pseudopods are structures in the amoeba that allow movement of the cell as well as help the amoeba to trap food by engulfing the particles. The species of amoeba are differentiated based on pseudopods. Amoeba also possess contractile vacuoles that helps it to get rid of the extra water.
Selective permeability, made possible in cells by the phospholipid bilayer that makes up the plasma membrane, is basically monitoring and regulating what can and can't enter the cell. It is carried out by a series of membrane proteins that act as channels to polar molecules, opening to allow them in and closing to prevent their entry. This is possible because the hydrophobic tails of the phospholipid molecules repel polar molecules and so prevent their entry unless through a channel.
