Cell Transport

Front

What is cell transport?

Back

Cell transport refers to the movement of substances into and out of cells, which is essential for maintaining homeostasis.

Front

What is endocytosis?

Back

Endocytosis is a type of cell transport where the cell engulfs substances to bring them inside.

Front

What is exocytosis?

Back

Exocytosis is a process where substances are expelled from the cell.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, moving from high to low concentration.

Front

What is active transport?

Back

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

Front

What does the cell membrane do?

Back

The cell membrane controls what substances can enter or leave the cell, helping to maintain homeostasis.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.

Front

What happens during facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport where substances move across the cell membrane with the help of transport proteins.

Front

What is the role of transport proteins?

Back

Transport proteins help move substances across the cell membrane, especially those that cannot easily pass through.
