Quiz Study Guide: Measurement, Cell Structures, and Transport

Vocabulary flashcards generated from the Quiz Study Guide covering ruler measurements, tonicity definitions, cell structures, and membrane transport processes.

Millimeter (mm)

A unit of measurement indicated by the small divisions on a ruler, where there are $10\,\text{mm}$ in $1\,\text{cm}$.

Centimeter (cm)

A unit of measurement indicated by the larger numbered markings on a ruler, equal to $10\,\text{mm}$.

Isotonic Solution

A solution that has the same concentration of solutes as another solution, leading to no net movement of water across the membrane.

Hypertonic Solution

A solution with a higher concentration of solutes compared to another solution, causing water to move out of the cell, potentially leading to cell shrinkage.

Hypotonic Solution

A solution with a lower concentration of solutes compared to another solution, causing water to move into the cell, potentially leading to cell swelling or bursting.

Cell Membrane

A cellular structure that controls the movement of substances in and out of the cell and provides structure and protection.

Mitochondria

The powerhouse of the cell, where energy (ATP) is produced through cellular respiration.

Osmosis

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