Question

1. which types of cells have a cell membrane?
2. true or false: the phospholipid bilayer is also referred to as the fluid mosaic model.

Explanation:

1. All cells, whether prokaryotic or eukaryotic, have a cell membrane. It is a fundamental structure that encloses the cell and regulates the movement of substances in and out of the cell.
2. The fluid mosaic model describes the structure of the cell membrane. The cell membrane is composed of a phospholipid bilayer with embedded proteins. The phospholipid bilayer provides a basic structure, and the proteins are scattered throughout, giving the membrane a mosaic - like appearance. The fluidity comes from the ability of the phospholipids and some proteins to move laterally within the membrane.

Answer:

1. All cells (prokaryotic and eukaryotic) have a cell membrane.
2. True.
