Q

Vacuoles

A

Membrane-bounded sac, larger than a vesicle; usually functions in storage and can contain a variety of substances. In plants, the central vacuole fills much of the interior of the cell

Q

Resolving Power

A

Resolving power is the ability of an imaging device to separate distinctive points of an object; it is important because the more resolving power a microscope has the better we can see the cell and its structures
