1. Centrioles
are only found in __________________ cells.
They function in cell _____________________. They have _____ groups of _____ arrangement of the protein
fibers. Draw a picture of a centriole
in the box. |
Centriole |
2. Lysosomes
are called ______________________ sacks. They are produced by the
________________ body. They consist of a single membrane surrounding powerful
_______________ enzymes. Those lumpy brown structures are digestive
_____________. They help protect you
by __________________ the bacteria that your white blood cells engulf. _______________ act as a clean up crew for
the cell. Zoom in and draw what you
see. |
Lysosomes |
3. Chloroplasts
are the site of ______________________.
They consists of a __________ membrane. The stacks of disk like
structures are called the ______________. The membranes connecting them are
the _________________ membranes. Zoom in and draw a picture. |
Chloroplasts |
4. Mitochondrion
is the _______________________ of the cell.
It is the site of _______________________. It has a ____________________ membrane. The inner membrane is where most
_______________ respiration occurs.
The inner membranes is __________ with a very large surface area.
These ruffles are called ___________.
Mitochondria have their own ________ and manufacture some of their own
_______________. Draw a picture of
the mitochondrion with its membrane cut.
|
Mitochondrion |
5. Endoplasmic Reticulum (ER) is
a series of double membranes that ________ back and forth between the cell
membrane and the _______________.
These membranes fill the ____________________ but you cannot see them
because they are very ___________________. The rough E.R. has
__________________________ attached to it. This gives it its texture. These
ribosomes manufacture __________________________ for the cell. The ribosomes are the
______________________________ which manufacture proteins. Draw the rough ER with a ribosome. |
Endoplasmic
Reticulum (ER) |
6. Smooth E.R.
____________ ribosomes. It acts as a __________________________ throughout
the cytoplasm. It runs from the cell membrane to the nuclear ________________
and throughout the rest of the cell.
It also produces ___________________ for the cell. Draw a picture of
the smooth ER. |
Smooth
ER |
7. Cell Membrane
performs a number of critical functions for the ________. It regulates all that _____________ and
leaves the cell; in multicellular organisms it allows _________
recognition. Draw and shade the cell
membrane. |
Cell
Membrane |
8. Nucleus is called the
______________________ of the cell. It is a large __________ spot in
eukaryotic cells. It _________________ all cell activity. The nuclear membrane has many
____________________. The thick ropy
strands are the _____________________________. The large solid spot is the
_____________________. The nucleolus
is a spot of __________________ chromatin.
It manufactures __________________________. The chromatin is _______________ in its active form. It is a
__________________________________ of DNA and histone proteins. It stores the
information needed for the manufacture of ____________________. Draw a picture of the nucleus and its
nucleolus. |
Nucleolus |
9. Golgi Body
is responsible for packaging _________________________ for the cell. Once the proteins are produced by the
______________ E.R., they pass into the _______________ like cisternae that
are the main part of the Golgi body.
These proteins are then squeezed off into the little _________________
which drift off into the cytoplasm.
Draw a picture of the Golgi Body as it is squeezing off the proteins. |
