Light Microscope correct answers An optical instrument with lenses that refact visible light to magnify
images of specimens
Light Microscope correct answers An optical instrument with lenses that refract (bend) visible light to
magnify images of specimens.
Organelles correct answers A membrane-enclosed structure with a specialized function within a cell.
Electron Microscope correct answers Microscope that forms an image by focusing beams of electrons
onto a specimen.
Transmission Electron Microscope correct answers An electron microscope used to study the internal
structure of thin sections of cells
Scanning Electron Microscope correct answers An electron microscope used to study the fine details of
cell surfaces
Scanning Electron Microscope correct answers SEM
Transmission Electron Microscope correct answers TEM
Cell Fractionation correct answers Technique in which cells are broken into pieces and the different cell
parts are separated
Prokaryotic Cell correct answers A type of cell lacking a membrane-enclosed nucleus and membrane-
enclosed organelles; found only in the domains Bacteria and Archaea. "Before Neculeus"
Eukaryotic Cell correct answers A type of cell with a membrane-enclosed nucleus and membrane-
enclosed organelles. Examples of organisms with these cells are protists, plants, fungi, and animals.

Cytoplasm correct answers A jellylike fluid inside the cell in which the organelles are suspended
Plasma Membrane correct answers A selectively-permeable phospholipid bilayer forming the boundary
of the cells
Nucleus correct answers Control center of the cell. Contains DNA.
Nuclear Envelope correct answers A double membrane that surrounds the nucleus in the cell
Nuclear Lamina correct answers A netlike array of protein filaments lining the inner surface of the
nuclear envelope; it helps maintain the shape of the nucleus.
