Page 1: Cell Structure and Transport

A collection of vocabulary flashcards covering the key cell biology and cellular transport topics outlined on Page 1.

Cell structure

The internal organization, components, and organelles that make up a biological cell.

Specialised Cells

Cells that have developed specific structural adaptations to carry out particular functions within an organism.

Using a microscope

The laboratory technique of preparing, mounting, and magnifying biological specimens for visual examination.

Magnification

The degree to which the visible image of an object is enlarged compared to its actual size, calculated as $\text{Magnification} = \frac{\text{Image size}}{\text{Actual size}}$.

Diffusion

The passive net movement of particles from an area of higher concentration to an area of lower concentration down a concentration gradient.

Osmosis

The diffusion of water molecules from a dilute solution to a more concentrated solution across a partially permeable membrane.

Active Transport

The movement of substances across a cell membrane against a concentration gradient, requiring energy transferred from respiration.
