Coloring—In all 3 diagrams, color the cell part whose structure & function
is described, & name it. Not every cell part will be found in every cell!
Color
Name of
Structure
coding
color
function
coded part
Brown
Structure—a rigid shell that lies outside of the cell
membrane
Function—provides extra protection for cells,
particularly preventing cells from bursting due to
taking in too much water.
Navy
Structure—a thin flexible layer that surrounds
EVERY cell
Function—controls movement of materials in and out
of the cell
Yellow
Structure—a gel that fills the volume of a cell
between the cell membrane and the nuclear
membrane
Function—supports the organelles and bathes them
in a chemical solution that serves as the cells
circulatory system
Red
Structure—2 layers of membrane that surrounds the
DNA & nucleolus in eukaryotic cells, but not
prokaryotic cells
Function—protects the DNA by controlling what
materials can enter and leave the region of the cell
Pink
Structure—a stack of membrane enclosed sacs that
looks like a stack of pancakes
Function—adds “shipping labels” to molecules made
in the endoplasmic reticulum so that they are
delivered to the correct organelles or even to plasma
membrane if they are to be exported from the cell
Orange
Structure—openings in the nuclear membrane can
be opened or closed
Function— selectively permit or block passage of
materials in and out of the nucleus so that the DNA
is protected
Black
Structure—rod like structures made of either
microtubules or microfilaments
Function— provide the framework of the cell,
2
providing its shape, allowing cells to move by
changing shape, and providing a set of “highways”
for moving organelles from place to place within the
cytoplasm.
Dark
Structure—tiny bundles of proteins and RNA made
purple
of 2 subunits and assembled in the nucleolus
Function—read genetic information (RNA) that
provides a pattern from which it assembles proteins
Dark
Structure—found only in autotrophic/producer
green
eukaryotic cells, these organelles are surrounded by
a two membranes and contain smaller membrane
enclosed sacs inside
Function—make sugars using sunlight energy,
carbon dioxide, & water, allowing cells to make food!
Light
Structure—found in all eukaryotic cells, these
green
organelles are surrounded by two membranes, the
inner of which is folded.
Function—release energy from sugar molecules to
that they can produce a different energy-storing
molecule called ATP; ATP is the form of energy used
by nearly all the proteins of a cell
Leave
Structure—these membrane sacs may be very large V_____
these
in plant cells, but are present in smaller forms in
uncolored other eukaryotic cells; some are given another
Or
name because they are carried along the
cytoskeleton to other locations
V______
Function—Those that are stationery are used for
storage in a eukaryotic cell; those that are carried
from place to place on the cytoskeleton are used to
deliver materials from one part to another w/in cells
Light blue Structure—these are long tubes from by folded
membranes inside all eukaryotic cells; some are
termed “smooth” because they are not coated in
ribosomes. Others are termed “rough” because they
are covered in ribosomes.
Function—the smooth form contains enzymes that
destroy toxins, as well as other enzymes that build
carbohydrates and lipids; the rough form contains
enzymes used to modify the proteins made by the
ribosomes on the surface. Vesicles bud off these
tubes to deliver their contents either to other
organelles or the membrane or to the golgi.
