energy (indicate which is
short-term and which is longterm)?


understand the functions and
structures of 8 organelles
HW: Graphic Organizer, Organelles Classwork (Wed.)
Organelles Project due Friday 3/3
The cell is the basic unit of life.
Cell Theory
1. All living things are
composed of cells.
2. Cells are the basic
units of structure and
function in living
things.
3. New cells are
produced from existing
cells.
Comparing the Cell to a Factory
Just like a factory, a cell
must:
• have a source of energy
• make a product(s)
• maintain, repair
themselves, and grow
• try to expand to new
locations
Organelles are specialized structures in cells that
perform specific functions.
Nucleus
The nucleus is the control center of the cell
• contains nearly all the cell’s DNA, or
instructions for the cell
main office of
the factory
Cytoplasm
The cytoplasm is the portion of the cell outside
of the nucleus.
• gel-like substance in which many chemical
reactions occur
(tiny dots)
Ribosomes
Ribosomes are where proteins are assembled.
• follow directions from the nucleus
assembly line
in the factory
Vacuole
The vacuole is a saclike structure that stores
materials such as water, salts, proteins, and
carbohydrates.
much larger in plants that in
animal cells
storage closet
in the factory
Mitochondria
Mitochondria convert the chemical energy
stored in glucose into a usable form (ATP).
• enclosed by a double
membrane
• powerhouse of the cell
the factory’s
power source
Chloroplast
Chloroplasts capture the energy from sunlight
and store it in the bonds of glucose.
• chloroplasts do photosynthesis
the factory’s
• only found in plants
solar panels
• contain green pigment
Cell (Plasma) Membrane
The outer border of every cell that regulates
what enters and leaves.
Cell Wall
The tough outermost layer of plant cells that
provides support and protection for the cell.
the cell wall is outside of
the cell membrane and is
made of cellulose

Which organelle regulates what enters and
leaves the cell?
Write on your board…
Where would a plant cell store the sugars it
makes during photosynthesis?
Write on your board…
Which organelle performs photosynthesis to
store energy in the bonds of glucose?
Exit Ticket
Match each organelle to its function (1 pt each):
1. ___ chloroplast
A. control center of cell
2. ___ ribosome
B. storage center
3. ___ nucleus
C. does photosynthesis
4. ___ vacuole
D. boundary of cell
5. ___ cell membrane
E. makes proteins
6. Describe 3 differences between plant and animal
cells (3 pts).
1. Cell Analogies Book
• Individually
• Choose plant or animal cell
• Write children’s book comparing organelles to
everyday objects
2. 3D Cell Model Project
• In pairs or individually
• Make a model of plant or animal cell
• Need organelle key & list of functions
3. The Organelle Rap
•
•
•
•
2-4 people
Mention 8 organelles and function of each
At least 10 lines
**BONUS POINTS if present to class on
Friday**
4. Visiting the Cell – Travel Brochure
• Individually
• Describing cell as attraction (zoo, mall, farm,
etc.)
• Ex) “Come to the ribosome, we’ll make
whatever kind of ice cream sundae you like!”
5. Cell Song Video Project
• 2-4 people
• Choose 1 of 3 songs (lyrics provided)
• All people in video at some point
