Full Answer

The structure of the amoeba is that of the protozoan. They are microscopic organisms. The type of amoeba studied in labs is the amoeba proteus, which is only 0.3 mm in diameter.

The creature is made up of only a single cell, and it has only a nucleus and cytoplasm. The amoeba has no chlorophyll or cell walls, so it takes in and digests solid food. It's possible to find these creatures in ditches, ponds, soil and moist locations.

The outer layer of the amoeba's cytoplasm is called an ectoplasm. It is a clear gel. The rest of the creature is primarily made up of endoplasm, which is more like a fluid that contains minute structures and granules. Uniquely, an amoeba does not have a typical shape and changes all the time; it changes particularly often when needing to move or feed.

Surprisingly, amoebas do not have flagella or cilia to help them move. They instead move by flowing the cytoplasm over mud, soil or other surfaces. When they need to eat, amoebas surround the microscopic plant or food source with pseudopodia. The food is then digested with enzymes produced by the amoebas.

    What is the difference between the cell wall and the cell membrane?

    A:

    Unlike the cell membrane, the cell wall is not common to all types of cells. A protective layer that surrounds the cell membrane, one of its main functions is to prevent over-expansion of a cell.

  • Q:

    What is an analogy for the cell wall?

    A:

    A good analogy for the cell wall is a sturdy fence or wall surrounding a castle, protecting the structure from harm and only allowing entrance by outsiders through specified gates and openings. In this scenario, the wall also keeps inhabitants safe inside, preventing them from venturing out into potential danger.
