The Cell Membrane

Identify the phospholipids

There are two layers of phospholipids that form the cell membrane. Therefore, another name for the cell membrane is the

• cytoskeleton

• homeostasis

• phospholipid bilayer

• cholesterol

The cell membrane is made of moving parts; therefore another term for it is the ​ (a)  

• fluid mosaic model
• semipermeable
• transport proteins

The cell membrane is made of biomolecules, including ​ lipids , ​ (a)   and carbohydrates.

• nucleic acids
• mitochondria
• proteins

• Allow passage of molecules

• Proteins

• Keeps the membrane fluid

• Phospholipids

Reorder the following

Which part of the phospholipid is HYDROPHILIC (loves water)?

Which part of the phospholipid is HYDROPHOBIC (fears water)?

Which part of the cell membrane is always on the OUTSIDE of the cell?

• Cholesterol

• Carbohydrates

• Proteins

• Phospholipids

Only some molecules may pass through the cell membrane. This characteristic is called
