AP Biology Unit 2 Review

Front

Which substance would most easily pass through the cell membrane?

Back

Oxygen is a small, nonpolar molecule that can easily diffuse through the lipid bilayer of the cell membrane.

Front

What is found in both plant and animal cells but is much larger in plant cells?

Back

Vacuole - a storage organelle that is much larger in plant cells, used for storing nutrients and waste products.

Front

Complex cell. Can be plant or animal. Contains membrane bound organelles.

Back

Eukaryotic Cell - characterized by the presence of a nucleus and other membrane-bound organelles.

Front

I am packing and shipping machine! Who am I?

Back

Golgi apparatus - an organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

Which statement about cholesterol molecules is true?

Back

Cholesterol molecules alter the fluidity of the membrane, helping to maintain its structure and function.

Front

What is the primary function of the cell membrane?

Back

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

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

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

Front

What is osmosis?

Back

Osmosis is the diffusion 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 mitochondria?

Back

Mitochondria are the powerhouse of the cell, generating ATP through cellular respiration.
