Biology: Cell Transport: Kahoot

Front

What is exocytosis?

Back

Exocytosis is an active transport process where cells expel materials, such as waste, by vesicles fusing with the plasma membrane.

Front

What is osmosis?

Back

Osmosis is the 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 happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrivel due to loss of water.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a passive transport process that uses protein channels to help move substances across the cell membrane without energy.

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 require energy and moves substances down their concentration gradient.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What role do cell membranes play in transport?

Back

Cell membranes regulate the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas, which drives the movement of that substance.

Front

What is endocytosis?

Back

Endocytosis is an active transport process where cells engulf materials from the outside environment by enclosing them in a vesicle.
