Daily Review Flashcard - Cell Membrane Structure (Task 11)

Front

What is the hydrophilic part of a phospholipid molecule?

Back

The 'head' of the phospholipid is hydrophilic.

Front

What do the tails of phospholipids in a cell membrane do?

Back

The tails of the phospholipids face inward towards each other.

Front

How does a cell maintain homeostasis?

Back

A cell maintains homeostasis by regulating what enters and leaves the cell.

Front

What does the suffix -philic mean?

Back

The suffix -philic means 'loving'.

Front

What is a primary component of the cell membrane?

Back

Phospholipids are a primary component that makes up the cell membrane.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic 'head' and two hydrophobic 'tails'.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane assist in transport, communication, and structural support.

Front

What is the function of carbohydrates in the cell membrane?

Back

Carbohydrates serve as recognition sites for cell signaling and communication.

Front

What is the fluid mosaic model?

Back

The fluid mosaic model describes the cell membrane as a flexible layer made of lipid molecules with embedded proteins.

Front

What is the significance of the cell membrane's selective permeability?

Back

Selective permeability allows the cell to control its internal environment by regulating the movement of substances.
