Question

A plasma membrane and a cell wall _____.

Answer 1

Answer;

D. Have different structures and different functions

A plasma membrane and a cell wall have different structures and different functions.

Explanation;

• Plasma membrane is a structure that is found in both animal cell and plants cells. It is made up of a bi-layer consisting of lipid and proteins. Plasma membrane are semi-permeable which means the allow selective movement of materials in and out of the cell.

• Cell wall, on the other hand is a structure that is found on plant cells and lacks in animal cell. It contains cellulose in its structure which enables it to be rigid and enhances it protect the cell from mechanical damage from harsh conditions such as pressure in the outside environment.

Answer 2

A plasma membrane and a cell wall have different structures and different functions.

Further Explanation:

Plasma membrane present in all the animals and plants. A cell wall covers the plasma membrane in plants. The plasma membrane is mainly made up of lipid bilayer which is semi-permeable to some molecule, ions and gases. Through this, the plasma membrane regulates the efflux and influx of a molecule.

Major functions of a plasma membrane are:

• Maintain the structure of a cell.
• Help in interaction with other cells.
• Protect outside.
• Help in the transport of toxic and nutrient substances or chemicals out of the cell.

The cell wall is the outermost covering of the cell. They are made up of hemicelluloses and cellulose, which provide the plant cell with extra support and protection. The cell wall is not present in an animal cell. The prokaryotic cell wall provides more protection than the eukaryotic cell wall. They help to maintain the shape of a cell and provide defense against dehydration.
