First Five
In your notebooks silently answer the following:
Perform a self evaluation on yourself in regards to the quiz we took.
Did you study?
How did you study?
How well do you think you did?
If you think you did poorly why do you think you should do next time?
If you think you did well, explain why.Slide2
Announcements
Past Due:
Kingdom Classification
Lizard Phylogeny
Check your gradesSlide3
Presentation Time
Presentations should last roughly 2 minutes.
You will receive a graded rubric next class.
Once presentations are done everyone needs to perform an evaluation on themselves and their group members. This will be part of your rubric.
Did everyone contribute?
If no, who didn’t
If yes, what was the contribution.Slide4
Key Ideas of Cells
Cells are highly organized
Different parts of the cells have specific functions
Today, we will be focusing on “Eukaryotic” cells, meaning plant and animal cells. Slide5
Variation in Cells
Important for nowSlide6
What are
organelles
?
Definition:
Organelles
are specialized cell parts that carry out a specific job
You have a body that has organs that do specific things so your whole body will work. An organelle is a little organ for the cell.
Slide7
Nucleus
“The Control Center”; a large organelle in the center of the cell that controls everything that happens in the cell
Stores and protects all genetic material (DNA) needed to make proteinsSlide8
Control center for plant and animal cells:
Chromosome
= coiled DNA: contains
instructions
for
characteristics
of an organism.
Chromatin
=
protein composing chromosomesSlide9
Let’s use an analogy:
The cell is like a nightclub!
Nucleus is the DJ
The DJ controls what music gets played at the club and also holds all the CDs/ mp3 songs at his booth
The Nucleus is like a control center for the cell and stores all the DNA (genetic information) for the entire cell!Slide10
Cytoplasm
Jelly-like fluid that holds all the organelles outside of the nucleus
Provides support for the cell and structures
Slide11
Cell Analogy:
The Nightclub
Cytoplasm is the air inside the club
All dancers in the club need air that contains all the gases to survive and have a good time
The cytoplasm in the cell supports all the organelles and has all the needed molecules for the cell to surviveSlide12
Cell membrane
Partially permeable barrier that surrounds the cytoplasm
Controls what goes into and out of the cellSlide13
Cell Analogy: The Nightclub
The cell membrane is the bouncer at the door of the club
The bouncer decides who gets to enter the club and who should be kicked out
The cell membrane protects the cell by controlling what enters and leaves the cell Slide14
Stop-and-jot
What is a body part that is similar to each of the cell parts we just discussed?
Nucleus
Cytoplasm
Cell membraneSlide15
Ribosome
a tiny organelle that helps the cell make protein by linking amino acids together. It floats freely in the cytoplasm
Function
:
Links
amino acids together to form proteins for the cellSlide16
Cell Analogy: The Nightclub
Ribosome is like the snack machine
The snack machine in the club is there to feed hungry dancers and is usually small and out of sight from everyone. It takes the code you enter and gives you a snack. Most snacks contain protein to satisfy your hunger.
The ribosome is very small and helps make proteins which fuel all the cells’ processes.Slide17
ENDOPLASMIC
RETICULUM (ER):
Network of tubes that produces, processes, distributes proteins
Rough or smoothSlide18
Endoplasmic Reticulum
“
Rough” with Ribosomes
for protein synthesis
“Smooth” =
Membrane “highway”
For transport of materials Slide19
Cell Analogy: The Nightclub
The chef/bartender of the club
Takes protein materials (food or drink) and modifies it to meet the need of the customerSlide20
GOLGI APPARATUS:
Membrane bound sacs that process, package, sort, and deliver proteinsSlide21
Cell Analogy: Golgi Apparatus
Waitress at the club that makes sure to deliver your order to your tableSlide22
Mitochondria
a bean-shaped organelle that creates all the energy the cell needs to survive
Second-largest organelleSlide23Slide24
Cell Analogy: The Nightclub
Mitochondria are like the speakers of the sound system.
The speakers play all the music in the club which gives dancers the energy to have a good time. Music is similar to energy!
The mitochondria supply all the energy needed for the cell to surviveSlide25
Chloroplast
= absorbs light, changes light energy into chemical energy for photosynthesis = Gr
EEN SacksSlide26
VACUOLE:
Sac-like structure in the middle of the cell that stores water, food, enzymes that the cell needsSlide27
Vacuole
=
storage for food and water
Why are plant vacuoles larger than animal vacuoles?
Plant VacuoleSlide28
Do you see 2
Contractile vacuoles
in this
Paramecium
?
Some Animal cell vacuoles pump water out by contracting
:Slide29
Cell Analogy
Storage basement beneath the club to hold extra equipment, food, drinks, and tablesSlide30
Lysosome:
Contains digestive enzymes
Breaks down large moleculesSlide31
First Five
Silently review today's worksheet and grab a computerSlide32
Cell Structure Web Activity
Get
a computer and
the handout
Complete the first side of the handout using the laptop
Use colored pencils to color the pictures on the back
Answer the questionsSlide33
Review TimeSlide34
Name that Organelle!
Choose the name that matches the organelle being described:
Nucleus
Cytoplasm
Cell membrane
Ribosome
Mitochondria
Endoplasmic reticulum
Vacuole
ChloroplastSlide35
Round 1
Jelly-like material that supports the cell and holds all molecules needed by the cell Slide36
Contains enzymes to digest and breakdown material Slide37
Links amino acids together to form proteins for the cell Slide38
Stores water, food, enzymes that the cell needs Slide39
Thin layer that controls what materials can move in and out of the cell Slide40
Contains enzymes that process, package, sort, and deliver proteins Slide41
Stores and protects all genetic material (DNA) needed to make proteins Slide42
Produces, processes, distributes proteins Slide43
Creates all the energy the cell needs to survive Slide44
Bonus: Label this diagram
First, on your whiteboard, number from 1 to 10. Then, you will write down the names of the cell parts next to each number.Slide45
