What is a common trait of both chloroplasts and mitochondria?

Back

Both have their own DNA.

Front

How do small, nonpolar molecules interact with a cell membrane?

Back

They easily pass through a membrane's lipid bilayer.

Front

Which organelle is abundant in salivary glands that produce enzymes?

Back

Golgi apparatus.

Front

What solution can be used to lyse red blood cells while preserving white blood cells?

Back

Hypotonic solution.

Front

What process is used to move large molecules out of the cell?

Back

Exocytosis.

Front

Define exocytosis.

The process by which large molecules are transported out of the cell via vesicles.

Front

What is the function of the Golgi apparatus?

Back

To modify, sort, and package proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes synthesize proteins by translating messenger RNA (mRNA).

Front

What is the difference between passive diffusion and facilitated diffusion?

Back

Passive diffusion does not require transport proteins, while facilitated diffusion does.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution, causing cells to swell.
