Microscopy. Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues. [2][3][4][5] Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. [5][6] Although one may divide microscopic anatomy ...
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
Giovanni Faber. Lincean, naming the microscope. Giovanni Faber (or Johann Faber, sometimes also known as Fabri or Fabro; 1574–1629) was a German papal doctor, botanist and art collector, originally from Bamberg in Bavaria, who lived in Rome from 1598. He was curator of the Vatican botanical garden, a member and the secretary of the Accademia ...
In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all living organisms and also the basic unit ...
Optical microscope. The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
Robert Hooke FRS (/ hʊk /; 18 July 1635 – 3 March 1703) [4][a] was an English polymath who was active as a physicist ("natural philosopher"), astronomer, geologist, meteorologist and architect. [5] He is credited as one of the first scientists to investigate living things at microscopic scale in 1665, [6] using a compound microscope that he ...
Organelle. In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive. Organelles are either separately enclosed within their own lipid ...
