Definitions

calculated by multiplying the magnification of the eyepiece by the magnification of the objective lense

light microscope that has two lens systems: the objective and the eyepiece

Lens that stays in focus when magnification/focal length is changed.

the object in the center of view will remain in the center when the objective is rotated

adapting for or using both eyes

• the distance between the nearest and the furthest objects that give an image judged to be in focus in

The extent of the visible image field that can be seen

distance between the front lens of the objective and the coverslip

Process by which molecules of a solvent pass through a semipermeable membrane, equalizing the concentrations on each side

process of passive transport which molecules diffuse across membranes with the help of transport proteins

the movement of ions across a cell membrane into a region of higher concentration assisted by enzymes which require energy

transport of a substance across a cell membrane by diffusion that does not require energy
