organelles
TRANSCRIPT
LAUNCH • Pick two organelles from
yesterday, describe their function and draw a quick sketch
LAUNCH • What are the differences and
similarities between a prokaryotic and eukaryotic cell? What are examples of each?
Parts of the Cell
Plant vs Animal Cells
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?
Control CenterHolds genetic
material
Nucleus
Nu
cleu
sLily Parenchyma Cell. Note the large nucleus and nucleolus in the center of the cell, mitochondria and plastids in the cytoplasm.
Nucleus
• Function: Control center of the cell, holds genetic information of DNA
• Found: In all Eukaryotic Cells (both plant and animal cells have nuclei)
• Analogy: Ms. Klaffky (principal)
Power Station Produces Energy
Mitochondria

Mitochondria
Mitochondria
• Function: convert chemical energy stored in food into compounds which cell can use for energy
• Found: In All Eukaryotic Cells in the cytoplasm
