Vocabulary -
1. Cell Membrane -the phospholipid bi-layer that covers a cells surface and acts as a barrier between the inside of a cell and the cells environment
2. Cell Wall - rigid outer layer of the cell. Found in plant cells and some bacteria (prokaryotes)
3. Chloroplasts - an organelle found in plant cells where photosynthesis occurs capturing sunlight and converting it to food
4. Cytoplasm - region of the cell within the membrane that includes the fluid, the cytoskeleton, and all the organelles except the nucleus.
5. Eukaryote - an organism made up of cells that have membrane bound organelles, eukaryotes included protists, animals, plants, and fungi.
6. Homeostasis - the ability of living things to maintain a balanced environment internal environment in response to external conditions. ex - shivering when its cold, drinking water when you are dehydrated.
7. Mitochondria - the organelle found in eukaryotic cells that is the site of energy release, the "powerhouse " of the cell
8. Nucleus - a membrane bound organelle that contains the cells DNA (genetic material) and controls the cells processes like growth, metabolism and reproduction.
9. Prokaryote - a single celled organisms that does not have a nucleus or membrane bound organelles, include Archaebacteria and Eubacteria
10. Vacuole - a fluid filled structure found in the cytoplasm of eukaryotic cells.

HOT Questions
1. How do the structures and processess of the cell work toghether to maintain homeostasis?
2. How does the stucture of the cell wall contribute to it's function?
3. Why can't animal cells make their own food?
4. What do animal cells have to have or be able to do in the absence of a large central vacuole, chloroplasts, and a cell wall?
CELLS CELLS
Original Rap by Ms. Quitmeyer
Today's the day were gonna learn about the cell,
If I teach it okay, you'll know it very well
So listen up 6th graders-
-no room left for haters
lets talk about the building blocks of life- cells that make us.
Cells, cells they're made of organelles
Try to pull a fast one, the cytoplasm gels
The nucleus takes over controllin' everything
The party don't stop 'till the membrane blocks the scene
Inside the vacuole we can float around for hours
Running round with chloroplasts, lovin' sunlight showers
Cells, cells, they're made of organelles
First things first, there's two different types
animal and plant cells that make up all life.
The little things that make up microscopic cells,
The main structures- yeah, we call them organelles.
Now let's break it down and get some information
How do cells work? It's a crazy combination!
Cells, cells they're made of organelles
Try to pull a fast one, the cytoplasm gels
The nucleus takes over controllin' everything
The party don't stop 'till the membrane blocks the scene
Inside the vacuole we can float around for hours
Running round with chloroplasts, lovin' sunlight showers
Cells, cells, they're made of organelles
The cell membrane is the border patrol,
Who can cross over?
The membrane lets 'em know
The gooey stuff inside, is called the cytoplasm
It holds the organelles- don't worry, plasm-has 'em!
In the middle of the cell you'll find the big brain,
The nucleus surrounded by nuclear membrane
Don't forget the vacuole filled up with water
It's a basic need for life when this rap keeps getting hotter!
Cells, cells they're made of organelles
Try to pull a fast one, the cytoplasm gels
The nucleus takes over controllin' everything
The party don't stop 'till the membrane blocks the scene
Inside the vacuole we can float around for hours
Running round with chloroplasts, lovin' sunlight showers
Cells, cells, they're made of organelles
The mitchondria's something every cell needs,
Breaking down the food and releasin' energy.
There's a place inside the cell where chemicals are stored, the squiggly golgi bodies,
releasin' even more.
Yo hangin' in the cell is endoplasmic reticulum, synthesizin' enzymes for respiration, and um...
If you still think that this rap is whack, remember ribosomes making proteins gettin' jacked! –
Cells, cells they're made of organelles
Try to pull a fast one, the cytoplasm gels
The nucleus takes over controllin' everything
The party don't stop 'till the membrane blocks the scene
Inside the vacuole we can float around for hours
Running round with chloroplasts, lovin' sunlight showers
Cells, cells, they're made of organelles
Lookin at the plant cell, weird and green
two more parts is all it takes you see?
Cell wall knows what's up when it comes to keepin' structure
Strong with cellulose, this cell can't get much tougher.
C-H- L-O- R-O -- Plast,
These little green machines are havin' a blast
Photosythenisizing- filled with chlorophyll –
they hit the cell club, runnin' up a high bill-
Cells, cells they're made of organelles
Try to pull a fast one, the cytoplasm gels
The nucleus takes over controllin' everything
The party don't stop 'till the membrane blocks the scene
Inside the vacuole we can float around for hours
Running round with chloroplasts, lovin' sunlight showers
Cells, cells, they're made of organelles
Essential Questions
1. How are plant and animal cells alike in structure and function and how are they different? Animal cells and plant cells share some similar structures. The nucleus of eukaryotic cells controls all of the cells functions. The mitochondria converts nutrients into energy the cell can use to carry out its functions. The cytoplasm, a gel like substance, is found within the cell membrane and is where all of the cell's organelles are contained. Plant cells contain unique structures that animal cells do not. The cell wall supports the plant's rigid structure. The chloroplast contains chlorophyll, which captures sunlight to aid in photosynthesis.
2. Explain how the functions of organelles work together within a cell to maintain Homeostasis. Organelles maintain homeostasis inside the cell by regulating the amount of water entering and exiting the cell, as well as taking in nutrients and removing wastes as needed.
3. Explain why some scientists say that plant cells are more complicated than animal cells. Plants create their own food and have a cell wall and large vacuoles for water storage.
