Researchers use fluorescent labels and light microscopy to.

a
.
produce movies of cells as they grow, divide, and develop.
b
.
scan cells with laser beams.
c
.
follow molecules moving through the cell.
d
.
build three-dimensional images of cells.

Researchers can use fluorescent labels and light microscopy to follow molecules moving through the cell. Confocal light microscopy, which scans cells with a laser beam, makes it possible to build three-dimensional images of cells and their parts.
