LAUNCH • Pick two organelles from
yesterday, describe their function and draw a quick sketch
![Page 2: Organelles](https://reader035.vdocument.in/reader035/viewer/2022062703/5555218eb4c9058b2f8b562f/html5/thumbnails/2.jpg)
LAUNCH • What are the differences and
similarities between a prokaryotic and eukaryotic cell? What are examples of each?

ANALOGY!
Organelles perform the functions of the cell just like different people and places
perform the functions of LPS!
If the nucleus of a cell is analogous to Ms. Klaffky, the principal, what function do you think the nucleus does?
