Cells fall into two broad categories, depending
on whether they contain a __(1)__. The
nucleus controls many of the cell’s __(2)__.
__(3)__ are cells that contain nuclei. __(4)__
are cells that do not contain __(5)__.

Cells come in a great variety of shapes and amazing
range of __(1)__. Although typical cells range from
5 to __(2)__ micrometers in diameter, the tiniest
mycroplasma bacteria are only 0.2 micrometers
across. The giant __(3)__ Chaos Chaos may be 1000
micrometers in diameter, large enough to be seen
with the __(4 – two words)__. All cells have two
characteristics in common. They are all surrounded
by a barrier called a __(5 – two words)__ and they
contain __(6)__.

In the same way that the main office controls a
large factory, the __(1)__ is the control center of
the cell. The nucleus contains nearly all of the
cell’s __(2)__ and with it the coded instructions
for making __(3)__ and other important
molecules. Most nuclei also contain a small,
dense region known as the __(4)__. The
nucleolus is where the assembly of the __(5) __
begins.

One of the most important jobs carried out in
the cellular “factory” is making __(1)__.
__(2)__ are assembled on __(3)__.
Ribosomes of small particles of RNA and

instructions that come form the __(6)__.

Eukaryotic cells also contain an internal
membrane system known as the __(1)__ or
__(2)__. It is the site where lipids and __(3)__
are assembled and exported from the cell.
Rough ER is given this name because of the
__(4)__ found on its surface. The other
portion of the ER is known as __(5)__ because
ribosomes are not found on its __(6)__.

Even the neatest, cleanest factory needs a
__(1)__, and that’s what lysosomes are.
Lysosomes are small organelles filled with
__(2)__. One function of lysosomes is the

Every factory needs a place to store things, and
cells contain places for __(1)__ as well. Some
kinds of cells contain saclike structure called
__(2)__ that store materials such as __(3-four

single, large central vacuole filled with
__(4)__. Vacuoles are also found in some
__(5)__ and some __(6)__ cells.
