Unit 2: Cell Structure & Function Review

Front

What is the primary function of rough endoplasmic reticulum (Rough ER)?

Back

Rough ER synthesizes proteins and compartmentalizes the cell.

Front

What is the primary function of smooth endoplasmic reticulum (Smooth ER)?

Back

Smooth ER functions in detoxification and lipid synthesis.

Front

What type of solution causes red blood cells to shrink the most?

Back

A hypertonic sucrose solution.

Front

Where do the light-dependent reactions of photosynthesis occur?

Back

In the grana/thylakoid membrane.

Front

Which cube has a faster material exchange at the center: a 10cm cube or a 50cm cube?

Back

A 10cm cube because it has a larger surface area to volume (SA:V) ratio.

Front

What effect does a greater proportion of unsaturated phospholipids have on membrane fluidity?

Back

It increases membrane fluidity.

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 role of ribosomes in the cell?

Back

Ribosomes are responsible for protein synthesis.

Front

Explain the significance of the surface area to volume ratio in cells.

Back

A higher surface area to volume ratio allows for more efficient exchange of materials with the environment.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.
