Cellular Transport Study Check

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell engulfs a large substance from inside the cell and moves it outside, using energy.

Front

What happens to water when a cell is placed in a hypertonic solution?

Back

Water moves from the inside of the cell to the hypertonic solution.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

Is the cell membrane solid and rigid?

Back

False, the cell membrane is flexible and fluid.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process where particles that are too large to enter the membrane need help from channel proteins, and no energy is required.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.
