Cell Organelles & Transport

Front

What is osmosis?

Back

The diffusion of water through a selectively permeable membrane.

Front

What happens in a hypotonic environment?

Back

Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell.

Front

What is the cytoplasm?

Back

The jelly-like substance that is located between the cell membrane and the nucleus.

Front

How does water move in a hypotonic solution?

Back

The water level will increase on the left side.

Front

What is the cell wall?

Back

The rigid, outermost layer of the plant cell.

Front

What is the function of the cell membrane?

Back

It controls the movement of substances in and out of the cell.

Front

What are mitochondria?

Back

Organelles that produce energy through cellular respiration.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane proteins.

Front

What is active transport?

Back

The movement of molecules across a cell membrane using energy, usually against a concentration gradient.

Front

What is a vacuole?

Back

A storage organelle in cells that can hold various substances, including nutrients and waste products.
