

Identify and describe cell structures and functions.
Define organelles by their functions.
Nucleus

Analogy:




“The Control Center”
“The Boss”
“The Mayor”
Function: Contains DNA
and controls the cell.

DNA is the coded
instructions for making
proteins.
Ribosomes


Analogy: “Factory
Machines”
Function: Site of protein
synthesis.

Found both on rough ER
and throughout the
cytoplasm.
Endoplasmic Reticulum


Analogy: “Highway of the
cell”
Function: Site where
proteins/lipids are
assembled and delivered
through the cell.


Rough ER: studded with
ribosomes; it makes
proteins
Smooth ER: no ribosomes;
it makes lipids
Golgi Apparatus

Analogy:



“The Mailroom”
“UPS”/ ”Fed-Ex”
Function: Modifies, sorts,
and packages materials
for transport
inside/outside the cell.
Lysosomes

Analogy:



Function:



“Clean-up Crew”
“Janitors” (Custodial
Technician)
Breakdown materials so
the cell can use them.
Breakdown useless
organelles and dispose of
them.
Contain strong digestive
enzymes.
Mitochondria

Nickname:


“The Powerhouse”
Function: Creates energy
from the food you eat.


Has it’s own strand of DNA.
Almost all mitochondria
comes from the cytoplasm
of the egg cell (all
mitochondria came from
your mom).
