Cell Transport Chapter 6 Part 2 Test

Front

What is endocytosis?

Back

Endocytosis is a type of transport that involves the engulfing of substances by the cell membrane, forming vesicles to bring materials into the cell.

Front

What does it mean if a solution is hypotonic to a cell?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to flow into the cell, leading to an increase in cell volume.

Front

What happens to skin cells when they are placed in dishwater?

Back

Skin cells are hypertonic to the hypotonic dishwater, causing water to flow into the cells, leading to swelling and wrinkles.

Front

Describe the movement of water molecules when a concentrated salt solution is on one side of a membrane and a dilute salt solution is on the other side.

Back

Water molecules tend to move from the dilute salt solution to the concentrated salt solution.

Front

What occurs to a plant cell in a hypotonic solution?

Back

In a hypotonic solution, a plant cell will increase in turgor pressure as water enters the cell, making it firm.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, while a hypotonic solution has a lower concentration of solutes.

Front

What is turgor pressure?

Back

Turgor pressure is the pressure exerted by the fluid inside the central vacuole of a plant cell against the cell wall, helping maintain the cell's shape.

Front

What is osmosis?

Back

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

Front

What role do vesicles play in cellular transport?

Back

Vesicles transport materials into and out of the cell, facilitating processes like endocytosis and exocytosis.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles that fuse with the cell membrane, releasing their contents outside the cell.
