3.2   True/False Questions 1) All eukaryotic cells have a plasma membrane

Question : 3.2   True/False Questions 1) All eukaryotic cells have a plasma membrane : 1402889

 

3.2   True/False Questions

 

1) All eukaryotic cells have a plasma membrane composed of a phospholipid bilayer.

2) Based on all the characteristics of living organisms, a cell nucleus should be considered to be a living organism.

 

3) The genetic material of a prokaryotic cell is stored in a small nucleus located adjacent to the plasma membrane.

 

4) All waste, raw materials, and sources of energy for a cell must enter and leave the cell by passing through the plasma membrane.

 

5) The phospholipids, proteins, and cholesterol in the plasma membrane are firmly bonded to each other via covalent bonds, lending strength and appropriate rigidity to the membrane.

 

6) The plasma membrane is constructed in layers, with the protein layer innermost, the cholesterol layer in the middle, and the phospholipid layer outermost.

 

7) Water moves via osmosis from an area with a lower solute concentration to an area with a higher solute concentration.

 

8) Polar molecules cannot pass across a plasma membrane through the lipid bilayer because they are not soluble in lipids.

 

9) Receptors are membrane-bound proteins typically located on the cell surface that function to bind other molecules based on shape or structure.

10) Cells surrounded by plasma membranes and no cell wall need to maintain a certain cell volume because an influx of water would cause the cell to explode. In order to reduce cell volume, these cells increase the activity of their sodium-potassium pumps.
