Unit 2 AP Biology Insta-Review (Cell Structure & Function)

Front

What happens to water potential as solute concentration increases?

Back

The water potential decreases.

Front

What is the formula for calculating the volume of a cube?

Back

Volume = side length³

Front

Which organelle is responsible for synthesizing proteins for secretion or membrane-bound?

Back

Rough Endoplasmic Reticulum (Rough ER)

Front

How are thylakoids organized in chloroplasts?

Back

Thylakoids are organized in stacks called grana.

Front

Which molecule passes through the cell membrane easily?

Back

Carbon Dioxide (CO₂) passes through easily.

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 function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the primary function of ribosomes?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between rough and smooth endoplasmic reticulum?

Back

Rough ER has ribosomes on its surface and synthesizes proteins, while Smooth ER lacks ribosomes and is involved in lipid synthesis.

Front

What is the role of the plasma membrane?

Back

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