Even the surface of the cell membrane wasn't actually clear if you looked at it directly.

Forget about the cell membrane - ways to get things in and out of it must also have developed later.

This process actually occurs at the cell membrane of the bacteria.

They bear much of the basic features provided by cell membranes.

The cell membrane also changes, and it reacts first to the impact of heavy water.

There are several ways for proteins to be attached to a cell membrane.

Exit is likely to be by budding from the cell membrane.

Little compartments are created by using many cells, each with its own cell membrane.
