Cell Transport Flashcard 11/2

Front

What part of the cell regulates what can enter and leave the cell?

Back

Cell Membrane

Front

What type of transport is characterized by the cell taking in materials by engulfing them?

Back

Endocytosis

Front

What type of transport involves the movement of molecules from an area of higher concentration to an area of lower concentration without energy?

Back

Diffusion

Front

What type of transport uses transport proteins to move substances across the cell membrane?

Back

Facilitated Diffusion

Front

What is the term for the movement of water across a selectively permeable membrane?

Back

Osmosis

Front

What type of solution has the same concentration of solutes as the cell, resulting in no net movement of water?

Back

Isotonic Solution

Front

What type of transport requires energy to move substances against their concentration gradient?

Back

Active Transport

Front

What is the process called when the cell expels materials by vesicle fusion with the cell membrane?

Back

Exocytosis

Front

What is the primary function of the cell membrane?

Back

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

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell shrinks as water moves out.
