Unit 2 - AP Biology Exam Review

Front

What is the primary reason small cells are more efficient at obtaining nutrients?

Back

Small cells have a larger surface area-to-volume ratio, allowing for more efficient nutrient absorption.

Front

What structure is found only in plants and prokaryotes that gives them a rigid shape?

Back

Cell wall.

Front

What is the main difference between passive and active transport?

Back

Active transport involves moving solutes against the concentration gradient using ATP, while passive transport moves solutes with the concentration gradient without using ATP.

Front

What does the hydrophilic head of a phospholipid do in relation to water?

Back

It loves to interact with water and is polar.

Front

How can you identify eukaryotic cells based on their structures?

Back

Eukaryotic cells have membrane-bound organelles.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the role of the plasma membrane?

Back

The plasma membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

Define osmosis.

Back

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

Front

What is the significance of ATP in cellular processes?

Back

ATP provides the energy required for various cellular processes, including active transport.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

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