TEST REVIEW: Cells & Cell Transport

Front

What is a Eukaryotic Cell?

Back

A Eukaryotic Cell is a type of cell that has a nucleus and membrane-bound organelles. Examples include plant and animal cells.

Front

What is Passive Transport?

Back

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

Front

What is Active Transport?

Back

Active Transport is the movement of solutes against the concentration gradient, requiring energy (ATP) to move substances into or out of the cell.

Front

What structure is found in plants but not in fungi or animal cells?

Back

Chloroplast, which is responsible for photosynthesis.

Front

What is Facilitated Diffusion?

Back

Facilitated Diffusion is the process by which large molecules move across the cell membrane from high to low concentration through a protein channel.

Front

What is the function of the cell membrane?

Back

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

Front

What is Osmosis?

Back

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

Front

What are the main differences between Prokaryotic and Eukaryotic Cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while Eukaryotic cells have both.

Front

What is the role of Mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is a Concentration Gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, which drives diffusion.
