Cell transport

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, moving with the concentration gradient.

Front

What direction do molecules move during passive transport?

Back

Molecules move down or with the concentration gradient.

Front

What is active transport?

Back

Active transport is the movement of molecules against the concentration gradient, requiring energy.

Front

What is endocytosis?

Back

Endocytosis is a type of active transport that moves particles into a cell by enclosing them in a vesicle made from the plasma membrane.

Front

What is exocytosis?

Back

Exocytosis is the process of vesicles fusing with the plasma membrane to release their contents outside the cell.

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via a protein channel.

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 enter the cell.

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 leave the cell.
