Cell Transport

Front

What is the structure of the Cell Membrane?

Back

The Cell Membrane is composed of two layers of phospholipids, known as the phospholipid bilayer.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, a cell will swell and may burst due to the influx of water.

Front

What is a Channel Protein?

Back

A Channel Protein is a type of protein that allows specific molecules to pass through the cell membrane.

Front

What does A2 represent in a phospholipid?

Back

A2 represents the Hydrophobic lipid tail of the phospholipid.

Front

Why can animal cells burst in a hypotonic solution?

Back

Animal cells can burst in a hypotonic solution because they lack a rigid cell wall, unlike plant cells.

Front

What is the function of the Cell Wall in plant cells?

Back

The Cell Wall provides structural support and protection to plant cells.

Front

Define Osmosis.

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their concentration gradient.

Front

What role do phospholipids play in the cell membrane?

Back

Phospholipids form the basic structure of the cell membrane, creating a barrier that separates the interior of the cell from the external environment.

Front

What is a Marker Protein?

Back

A Marker Protein is a protein that helps identify the cell type and is involved in cell recognition.
