Do Now
1. Cells
2. Eukaryotes
3. Eukaryotic, since they have a nucleus. EU = You!
4. Animal cells can be round (or another shape),
while plant cells are generally square
5. Mitochondria is a cell organelle that is the
“powerhouse” of the cell and provides energy

SWBAT analyze the processes carried out by the
organelles in plant cells

WRITE-PAIR-SHARE
 List the organelles you learned yesterday that
appear in animal cells. Then, circle the ones you
think also appear in plant cells.
Organelles
 Organelles that are in both plant and animal cells:

Nucleus

Plant Cell Organelles
Plant Cells.
 Cellulose Cell Wall: a rigid
wall structure around the
cell that gives the cell a
rectangular and structural
support
Plant Cells.
 Large Central Vacuole: a
large “tank” in the middle of
the cell that holds water for
long periods of time.
 WRITE-PAIR-SHARE:
Animal cells have vacuoles
too, but much smaller. What
do you think led to this
difference?
Plant Cells.
 Chloroplasts: small organelles
in each cell that contain
chlorophyll responsible for
making energy during
photosynthesis
WRITE-PAIR-SHARE
 So, plant cells have mostly the same organelles as
animal cells, but also have a few extra organelles (as
well as a much, much larger vacuole). Why do you
think plant cells need more organelles?
PLANT CELLS
 Plant cells are more
complicated and have
more organelles than
animal cells, since plants
have to make their own
food (photosynthesis)
instead of eating it (like
animals)

3 Important Facts
 Complete the bottom box on your notes page to
sum up what you think were the most important
parts of today’s lesson
Partner Practice
 Complete the sheet labeled “Partner Practice” with
your partner at a noise level of 1
Broken Heart
 Today, you are going to become independent, literally
 You are playing the role of a plant cell who has decided
to breakup with your partner, an animal cell
 You will be writing an informal letter
 Use the knowledge of informal writing that you are
learning in ELA
 Use only scientific knowledge we’ve covered
 No “I’m breaking up with you because you never call!” or
“I don’t like the way you were flirting with the prokaryotic
cell!”
Break Up Letter: An
Example
Dear Prokaryotic Cell,
I know we had a lot of similarities. We both are
cells, which is the basic building block of living things. But
besides that, we are just too different. I am make up
multicellular organisms, and you are just a lonely, single
cell. I am complicated and made up of many organelles,
like a nucleus, mitochondria, and a cell membrane. You, on
the other hand, are just TOO BASIC! Finally, I have a
nucleus, and you don’t! Because of these differences I am
sorry to tell you that I think we need to break up. I hope
you understand.
Best, Eukaryotic Cell
