Cell Membrane & Passive Transport Review

Front

What happens to a cell in an isotonic solution?

Back

A cell in an isotonic solution will stay the same size.

Front

What type of solution can animal cells survive in?

Back

Animal cells can survive in isotonic solutions.

Front

What is the name of the water channel protein in a cell?

Back

The water channel protein in a cell is called aquaporin.

Front

Which part of a phospholipid is hydrophobic?

Back

The lipid 'tails' of a phospholipid are hydrophobic.

Front

What type of solution is characterized by a lower concentration of solutes compared to the cell?

Back

A hypotonic solution is characterized by a lower concentration of solutes compared to the cell.

Front

What is the primary function of the cell membrane?

Back

The primary function of the cell membrane is to regulate what enters and exits the cell.

Front

Define passive transport.

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What occurs during endocytosis?

Back

During endocytosis, the cell engulfs material from the outside environment.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher concentration of solutes than the cell, while hypotonic solutions have a lower concentration.
