Question

Which of the following are not characteristics of the plasma membrane? Select all that apply.
cellulose
phospholipids and protein
increased strength to the cell
selective membrane

Answer 1

phospholipids and increased strength to the cell selective membrane

Answer 2

Answer:

The characteristics of the plasma membrane are not the cellulose and increased strength of the cell.

Explanation:

The plasma membrane is the cell membrane that set the boundary between cell and cell organelles.

The functions of the plasma membrane in a cell are:

• To protect the cell and cell organelles from injuries.

• Acts as a surface for the exchange of materials in and outside the cell.

The components of the plasma membrane are:

• Phospholipid bilayer
• Protein (glycoproteins, peripheral membrane proteins)
• Carbohydrates
• Cholesterol

Here, cellulose is the characteristic of the plant cell wall not of the plasma membrane.

Hence, cellulose and the increased strength of the cell are not characteristics of the plasma membrane.
