Prokaryotes, Eukaryotes, Diffusion, Osmosis

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 osmosis?

Back

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

Front

What type of cell is a bacterium?

Back

Bacteria are examples of prokaryotic cells.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a simple, unicellular organism that lacks a nucleus and membrane-bound organelles.

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a complex cell that contains a nucleus and membrane-bound organelles.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus, while eukaryotic cells do.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, including processes like diffusion and osmosis.

Front

What is active transport?

Back

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

Front

What organelle is only found in eukaryotic cells?

Back

The nucleus is only found in eukaryotic cells.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell.
