Cell Transport

Front

What is active transport?

Back

Active transport is the movement of particles from an area of lower concentration to an area of higher concentration, requiring energy input.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically from an area of higher concentration to an area of lower concentration.

Front

What is endocytosis?

Back

Endocytosis is a type of active transport where cells engulf substances from the outside environment, bringing them into the cell.

Front

What is exocytosis?

Back

Exocytosis is a type of active transport where cells expel substances to the outside environment.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a greater solute concentration outside the cell compared to the inside, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

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

Front

What is an isotonic solution?

Back

An isotonic solution has equal solute concentrations inside and outside the cell, resulting in no net movement of water.

Front

What is homeostasis?

Back

Homeostasis is the state of stable internal and external conditions in a cell, essential for maintaining life.

Front

What role does the cell membrane play in transport?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is diffusion?

Back

Diffusion is the passive movement of particles from an area of higher concentration to an area of lower concentration.
