The ______________________states that living organisms are made up of basic units of
structure and function, called cells. Today, cells are classified in two groups according to
whether they contain membrane-bound ________________________.
_________________________ cells contain these membrane-bound structures, but
____________________________ cells do not. All cells contain a ___________________,
which controls what can enter and exit the cell.
Cell structures are located within a jellylike fluid called the _____________. Each structure
carries out a specific function. For example, the ______________________ is the control center
of the cell’s activities. The ______________________ are bean-shaped structures in the
cytoplasm that convert food energy to cellular energy or ATP. Other structures, called
______________________, contain enzymes that break down large molecules.
Within the cytoplasm is a system of membranes called the _____________________. Within
the folds of some of these membranes are tiny structures called ______________________,
where proteins are synthesized or made. Those membranes that contain these structures are
called ___________ endoplasmic reticulum. If they do not have the structures, they are called
____________ endoplasmic reticulum. Once proteins are made, they are often sent to the
_________________ _______________, where they are repackaged and distributed from one
part of the cell to another.
Plant cells differ from animal cells…
 First, plants have a rigid ______________________ made up of cellulose outside their cell
membranes.
 Second, plant cells contain ______________________, which converts light energy into
chemical energy.
 Third, they have one large central storage ______________________ that often occupies
most of the space inside a plant cell.
 Fourth, plant cells never have ________________ or ____________, though some animal
cells do!
