CP Biology First Semester Exam Review 2024

Front

What process is being shown in the image?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

The cell membrane is ______________, it regulates what can enter and leave the cell.

Back

Selectively permeable means that the cell membrane allows certain substances to pass while blocking others.

Front

Identify the tonicity of the solution in blue?

Back

Hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to enter the cell.

Front

During the light reactions of photosynthesis, _______ molecules absorb light energy.

Back

Chlorophyll is the green pigment in plants that absorbs light energy for photosynthesis.

Front

Identify this monomer:

Back

Amino acid is the building block of proteins, consisting of an amino group, a carboxyl group, and a unique side chain.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is a monosaccharide?

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What is a nucleotide?

Back

Nucleotides are the building blocks of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.
