Cell Membrane & Cell Transport

Front

What does 'Hydrophilic' mean?

Back

Hydrophilic refers to substances that are attracted to water and can easily dissolve in it.

Front

What does 'Hydrophobic' mean?

Back

Hydrophobic refers to substances that repel water and do not dissolve in it.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration.

Front

What are the two parts of a phospholipid?

Back

The two parts of a phospholipid are the Hydrophilic Head and the Hydrophobic Tail.

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.

Front

What does 'selectively permeable' mean?

Back

Selectively permeable means that the cell membrane allows certain substances to pass while blocking others.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane assist in transport, act as receptors, and provide structural support.

Front

What are lipids?

Back

Lipids are a group of organic compounds that are insoluble in water and include fats, oils, and phospholipids.

Front

What is the function of carbohydrates in the cell membrane?

Back

Carbohydrates in the cell membrane are involved in cell recognition and signaling.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
