Honors Biology First Semester Exam Review 2024

Front

What is a hypotonic solution?

Back

A solution that has a lower concentration of solutes compared to another solution, causing cells to swell and potentially burst.

Front

What is chemosynthesis?

Back

The process by which certain organisms create glucose from inorganic substances (like hydrogen sulfide) in the absence of light.

Front

What is osmosis?

Back

The movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

Where does photosynthesis occur in cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is a nucleotide?

Back

The monomer unit of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is an isotonic solution?

Back

A solution that has the same concentration of solutes as another solution, resulting in no net movement of water into or out of cells.

Front

What is active transport?

Back

The process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What are ribosomes?

Back

Cellular structures that synthesize proteins by translating messenger RNA.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane proteins.

Front

What is a monosaccharide?

Back

The simplest form of carbohydrates, consisting of a single sugar molecule, such as glucose or fructose.
