Transcript Functions of Parts of a Cell

Cell Function Sheet
• Have your sheet ready to write notes in.
• Read and understand each slide before
going to the next.
• The most important information is IN
PURPLE.
• Check off if the organelle is found in a plant
cell, animal cell, or both.
What are the functions of the organelles?
• LAPTOP/iPAD activity:

Find this presentation for today’s date.
Read each slide together.
Take notes by filling in blanks on your sheet.
AFTER ALL NOTES ARE DONE, get your
sheet of picture clues (from the basket on
demo table) to cut out and glue in the
appropriate box on your sheet.
Here come the organelles…!
Cell Wall
• Plant cells only
• Give plants their shape,
structure, support, and
protection
• Surrounds the cell
membrane
• Allows H2O, O2, and CO2,
to pass in and out of the
cell
Cell Membrane
• A continuous, almost
invisible structure
surrounding the cell
• Supports & protects
the cell
• Controls movement
of materials in and
out of the cell
Chloroplasts
• Plant cells only
• Uses energy from the sun to
make food for the plant
through photosynthesis
• Where photosynthesis takes
place
• Power generator for the plant
• Give plants their green color
Cytoplasm
• The cell’s environment or
inner space.
• Mostly made of water and
contains organelles
• The jellylike material
outside the cell nucleus.
Mitochondria
• Powerhouse of the
cell. Supplies
energy that the cell
needs.
• Breaks down sugar
molecules into energy
• Need oxygen to make
energy and give off
carbon dioxide as
waste
Nucleus
• The cell’s computer, brain,
or manager. Uses DNA to
control the cell’s activity
• Contains all the information
the cell needs to do specific
jobs, grow, and divide
• Information is stored in
DNA molecules
• Contains the nucleolus which
makes ribosomes
• Determines what proteins
will be made
Lysosomes
• Cell’s recycler. Breaks
down large food and
digests old cell parts.
• Contains enzymes which
break down the proteins
Ribosomes
Protein
• Produces protein which
is the Product of the
cell
• Cells need protein to
survive and grow
Protein
Vacuoles
• Storage bubbles found
in cells.
• Much larger in plant cells.
Store food or nutrients a
cell might need to
survive.
• Store waste products so
the rest of the cell is
protected from
contamination.
Packs
Golgi Bodies
• Packs and carries
proteins in little
bubbles that separate
and float into the
cytoplasm.
• Prepares the proteins
for use or delivery
outside the cell
Endoplasmic Reticulum (E.R.)
• Transportation system of
the cell. Carries
material through the
cell.
• Rough ER has ribosomes
attached to it so the
proteins they make can be
released directly into the
ER for transport
• Smooth ER collects things
and contains them
Nuclear Membrane
• Protects and guards the
nucleus. Allows materials
to pass in and out.
• Keeps the DNA inside the
nucleus
• Allows other materials to
pass in and out of the
nucleus
OBSERVE THE DIFFERENCES
BETWEEN ANIMAL & PLANT CELLS
Now get your sheet of pictures!
Protein
Cut out the symbols and glue them next to the
correct cell part, to help you remember the function
of the organelle. Hint: Go back to the slide to see
which picture goes with it!

Cell Functions
Answer Key
* Check if you
have all the
symbols in the
right boxes.
* Check if the
organelle is in
animal cells,
plant cells or
both.
* Then quiz a
partner about
the function of
each of these
organelles, by
taking turns
and using your
paper.

Clean-Up Directions
Shut down your laptop, or sign out on your iPad.
Return your device.
Put glue sticks back on the demo table.
Check the floor for scraps, and throw out.
View microscope specimens if you are all done!
