CELL PART ANALOGIES
Parts of a Cell
Cell Membrane
• The cell membrane
controls what goes in
and out of the cell.
• The cell membrane is
like a screen door,
because a screen
door holds things out
but lets air in.
Cytoplasm
• The cytoplasm holds
cell parts in place.
• The cytoplasm is like
nails or glue because
it holds things
together.
Nucleus
• The nucleus controls
all of the cells
activities.
• A nucleus is like a
tour guide because
they control all of the
places people go on
tours.
Lysosome
• A lysosome digests
and recycles
materials.
• A lysosome is like an
engine because an
engine recycles oil.
• It is the cell’s garbage
disposal.
Endoplasmic Reticulum
• The endoplasmic
reticulum is like a
road way in the cell.
• The endoplasmic
reticulum is like a
freeway, because it
gets people from
place to place.
Golgi Apparatus
• The Golgi apparatus
assembles, packages
and delivers.
• The Golgi apparatus
is like a post office,
because the whole
point of a post office
is to package and
deliver things.
Chromosome
• A chromosome stores
information.
• A chromosome is like
a flash drive or a book
because they store
information.
Centriole
• A centriole helps
organize the cell
when it is divided.
• A centriole is like a
secretary because
they organize things.
Cytoskeleton
• The cytoskeleton
holds the shape of the
cell.
• The cytoskeleton is
like the beams of a
house because they
help the house hold
it’s shape.
Mitochondria
• The mitochondria
burns food for energy
• The mitochondria is
like a fire because
fires burn wood for
energy.
Vacuole
• The vacuole is used
for storage (mostly for
water).
• The vacuole is like a
cupboard because
you store things in it.
Chloroplast
• The chloroplast turns
energy from the sun
into energy the cell
can use.
• A chloroplast is like a
solar panel because it
uses the sun’s energy
for other things.
Cell Wall
• The cell wall
surrounds the plant
cell and protects it.
• It is made of a hard
non-living substance
called CELLULOSE.
