A lens through which the eye views the image formed by the objective.

A microscope that uses light to view close ups of a specimen.

A unit of measurement equivalent to one thousandth of a millimetre or one millionth of a metre.

A unit of measurement equivalent to one billionth of a metre.

The part of the cell containing genetic material and bound by the nuclear membrane.

A lens that receives rays from the specimen and forms an image in the focal plane of an eyepiece.

A specialised part of a cell that has a specific function.

A sample to be examined or observed.

a small molecule is a low molecular weight organic compound that may regulate a biological process, with a size on the order of 1 nm. Most drugs are small molecules

An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.

A member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some which can cause disease.

The action of magnifying something or the process of being magnified.

Disease causing micro-organisms.

The ability to clearly distinguish between two separate but adjacent structures.

Scanning Electron Microscope

A microscope in which the specimen is examined using a moving electron beam from which the electrons are reflected to form a magnified three dimensional image.

Transmission electron Microscope

A microscope that passes beams of electrons rather than light through the specimen to view it at very high magnification.

An area of which there is reduced number of air particles.

A chemical within the substance that does the work

Without sex; involves only one parent.
