Unit 2 Review

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells have free floating DNA while eukaryotic cells have DNA contained in a nucleus.

Front

What structures do both prokaryotic and eukaryotic cells have in common?

Back

Cell membrane, cytoplasm, genetic material (DNA).

Front

What type of cellular transport moves from low concentration to high?

Back

Active Transport.

Front

What type of cell transport is represented by endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them.

Front

What is the function of the Golgi apparatus?

Back

It processes, packages, and secretes proteins; proteins are transported in vesicles.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is osmosis?

Back

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

Front

What is the role of the cell membrane?

Back

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

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is the site of many metabolic processes.
