7.3 Cell Boundaries and Transport (use for Unit 3 Flashcard 2)

Front

Phagocytosis

Back

Cell 'eating' - a process where the cell engulfs large particles or cells.

Front

What controls what substances enter or exit the cell?

Back

Cell membrane - a selective barrier that regulates the movement of substances.

Front

The cell membrane is made up of a

Back

Lipid bilayer - a double layer of phospholipids that forms the basic structure of the cell membrane.

Front

What type of solution is this cell in?

Back

Isotonic - a solution where the concentration of solutes is equal inside and outside the cell.

Front

Endocytosis moves large material

Back

Into the cell - a process where the cell membrane engulfs material to bring it inside.

Front

What is the function of the cell membrane?

Back

To protect the cell and control the movement of substances in and out.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane from an area of low solute concentration to high solute concentration.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell, causing the cell to swell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of the cell, causing the cell to shrink.
