Flagella are the structures that allow certain bacteria to attach to surfaces. In comparison, the cytoplasmic membrane inhibits phagocytosis allowing bacteria to escape death.

The statement provided seems to be a mix of correct and incorrect information. Let's clarify:

1. Flagella: These are long, whip-like structures that protrude from the cell body of certain bacteria and other microorganisms. They are primarily used for locomotion, or movement. They do not typically function to attach bacteria to surfaces; that role is more commonly associated with structures called pili or fimbriae.

2. Cytoplasmic membrane: This is a semi-permeable membrane that surrounds the cytoplasm of a cell, regulating the entry and exit of substances. It doesn't directly inhibit phagocytosis. Phagocytosis is a process used by certain cells of the immune system to engulf and destroy foreign bodies, including bacteria. Some bacteria can resist phagocytosis, but this is typically due to factors like the presence of a capsule, not the cytoplasmic membrane.

So, to correct the original statement: Flagella are structures that allow certain bacteria to move, while the ability of bacteria to resist phagocytosis and escape destruction by immune cells can be due to several factors, but is not directly related to the cytoplasmic membrane.
