1. What does pro mean?
CLASS TIME
Pro means before. Prokaryotic cells came before
other cells.
2. What does eu mean?
Eu means true. Eukaryotic cells are considered
true cells because they have a true nucleus.
3. What are the 2 main differences between prokaryotic
and eukaryotic cells?
Eukaryotic cells have a nucleus and other
membrane-bound organelles, which prokaryotic
cells lack.
4. What is an organelle?
A small structure found
within a cell that carries
out a specific task.
Organelles
A small structure within a eukaryotic cell (plant or
animal) that has a particular job or function.
Ribosomes School Metaphor
• The ribosomes are like factories because they
make/build proteins like a factory builds cars!
• (cars are the proteins! They are the product
the factory wants to make!)
Nucleus
•
•
•
•
Only Eukaryotic cells have them
Contains genetic material (DNA)
Controls cell processes
Like a “brain” because a brain controls your
body
Endoplasmic Reticulum Function
• Specializes in the synthesis
& transport of lipids and
membrane proteins
• Synthesis= to make or
produce
• Rough ER has ribosomes
(MAKES PROTEIN)
• Smooth ER lacks ribosomes
(MAKES LIPIDS)
Endoplasmic Reticulum: Cell Type
• All Eukaryotic cells (plant and animal)
ER School Metaphor
• The ER is like the hallways of a school because
it transports students and teachers from class
to class.
Golgi Apparatus
Golgi Function
• aka Golgi Bodies
• Where proteins are packaged and sent out or
exported from the cell.
Golgi: Cell Type/Picture
• All Eukaryotic cells (PLANT AND ANIMAL)
Golgi School Metaphor
• The Golgi bodies are like the UPS of a city
because this is where items (proteins) can be
packaged and shipped.
Vacuole
Vacuole Function
• Storage site for food and water
• Much larger in plant cells than in animal cells
Vacuole: Cell Type/Picture
• All Eukaryotic cells (PLANT AND ANIMAL)
• Plant= large
• Animal=small,
contractile
Vacuole School Metaphor
• The vacuoles are like the water towers of a
city because a water tower can store/keep
water for the city in case of a shortage.
Lysosomes
Lysosomes Function
• Contains digestive enzymes
• Breaks down large molecules and wastes
inside the cell
Lysosome: Cell Type/Picture
• All Eukaryotic cells (PLANT AND ANIMAL)
Lysosome School Metaphor
• Think Lysol, the cleaner
• The Lysosomes are like the landfills of a city
because this is where all the trash and waste
goes that keep the city clean.
Mitochondria
• 1= mitochonrion
• Multiple= mitochondria
Mitochondria Function
• Power house of the cell
• The site where energy is released from
glucose in the form of ATP
– We will learn more about this next unit!
Mitochondria: Cell Type/Picture
• All Eukaryotic cells (PLANT AND ANIMAL)
Mitochondria School Metaphor
• The mitochondria are like power plants of a
city because this is how we get energy!
Centriole
Centriole Function
• cell reproduction
Chloroplast
• Found in all plants and some protist (algae).
Cytoskeleton: Cell Type/Picture
• All Eukaryotic cells (PLANT AND ANIMAL)
Cytoskeleton School Metaphor
• The cytoskeleton is like the walls of a school
because this they support the building and
hold everything in place.
Group Work
• Work in your groups on your Cell City Project
• Due Tuesday!
• You are accountable…
– I expect you to be using this time wisely!
– Your entire group will receive a check if someone
leaves your group without permission
