The 4 main components of the building blocks of DNA are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).
3. Where in the eukaryotic cell is the DNA found?
In the eukaryotic cell DNA is found in the nucleus, the mitochondria, and the chloroplasts
4. List and describe as many functions of DNA in living things that you can think of (at least three!)
The main function/ role of DNA is the storage of information.
5. List each color that is represented for the nitrogenous bases located within the center of the molecule.

We have discussed the three jobs of the cell which are;
generate energy
making proteins and
creating more cells
Mitosis is the process by which new cells are formed from pre-existing cells in eukaryotes.
Use the Crash Course video on Mitosis to answer the following questions. Please answer the questions directly from the blog and highlight your final answer and skip lines if done on loose leaf. All questions must be answered by the end of class and submitted to jaharris@dc.seedschool.org for full credit. This assignment is one of the very first assignments of the 3rd quarter.

3D Cell Project ( Alaysia & Genai )
for our project Genai and i decided to do a plant cell model . Anyone can tell our model is a plant cell because it has a cytoplasm and a large vacuole . 
Both plants and animal cells have many similarities such as cell wall , lysosomes , mitochondria and vacuole. Unlike plant cells animal cells contain a smaller vacuole and flagella .

3D Cell model project (Dakara and Ashlee)
ANIMAL CELL CAKE
Ashlee and I decided to do an animal cell. You can tell it is an animal cell because animal cells are round VS plant cells that are rectangular.
ANIMAL VS PLANT
1.) Animal cells and plant cells are different in various ways.
•animal cells do not have a chloroplast but plant cells do.
•animal cell has no cell but plant cells do.
•the shapes are different
•an animal cell is smaller than a plant cell
MAJOR JOBS OF THE CELL
The three major functions of a cell are:
1. Make more cells
2. Energy conversion
3. Transport molecules
STEM CELLS
A stem cell is a cell that stores genetic information in the plant tissue.
Stem cells can be useful in these ways:
•increase understanding of how diseases occur.
-watching stem cells mature help doctors see how diseases Develop
•stems cells are a major key in cell regeneration
-helps repair damaged tissue
PHOTO GALLERY
3D Cell Model Project Jared Benjamin- Writing is Thinking
1. I created a plant cell and three distinguishable characteristics are the Cell Wall, which only are in plant cells. it also has chloroplast and a large vacuole that are exclusive to plant cells.
2. The Three basic functions of a cell are transport of molecules, conversion of energy and reproduction.
3. A stem cell is a cell that stores the genetic info inside the plant tissue.
4. Potential uses for stem cells are macular degeneration, heart disease and diabetes.

PROKARYOTIC vs. EUKARYOTIC
----------------------------------------
-Unicellular - Nucleus
-Bacteria - Multicellular
Both
------
-cell membrane
-ribosomes
-DNA
1. Plant cells are different from animal cells because they don't have as many organelles as the cell of animal. Also There are some things that plant cells have that animal cells don't such as,
-cell wall: help keep the cells shape and structure.
-large vacuole: where waste is composed
2. 3of the cells most important jobs are to:
make more cells
make proteins
&
make energy
3.the stem cells are in the tissues and organs of the plant.
4. Stem cells are used to make plants and make more of the same type of plant.
3D Cell ( Jamilya & Larry )
1. What kind of cell did you make and what are three distinguishing characteristics(cell parts, shape, etc) that made your cell different from the other types of cells? Make sure that you include the functions of the cell parts that you mention for full credit.
1A. I did a plant cell. It is square, it has a cell wall- a structural layer that surrounds some types of cells also outsided the cell membrane, and a large central vacuole- a large container that holds waste.
2. All cells have three major jobs that are needed in order to sustain homeostasis. What are theses three basic functions?
2A. To reproduce, make proteins, and make energy.
3. What is a Stem Cell and where do stem cells come from?
3a. A Stem Cell is a cell that has genetic information in the plant tissue.
4. What are some potential uses of Stem Cells?
4a. Stem Cells are directed to differentiate into specific cell types. The tissues treat burns, diabetes, and degeneration.

3D Cell Model Project (Daisha Thompson) - Writing is Thinking
1. What kind of cell did you make and what are three distinguishing characteristics that made your cell
different from other types of cells.
1a. I made a Plant Cell. Cell wall is one, Chloroplast is another and lastly the large vacuole. All of these represent the three distinguishing characteristics that made my cell different from the animal cell. The function of the cell wall is a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants. The function of the chloroplast is a plastid that contains chlorophyll and in which photosynthesis takes place. Lastly the large vacuole is the storage area for water and other substances.
2.All cells have three major jobs that are needed in order to sustain homeostasis. What are these three basic functions?
2a. The three basic functions are Transport of Molecules, Conversion of Energy and lastly Reproduction.
3. What is a Stem Cell and where do stem cells come from?
3a. A Stem Cell is a cell that has genetic information in the plant tissue.
4. What are some potential uses of Stem Cells?
4a. Stem Cells are directed to differentiate into specific cell types. The tissues treat burns, diabetes, and degeneration. 
Cell cake (JieJer Patrick)
This is a plant cell. A plant has a rectangular/square like shape. A pant cell is way different from a animal cell. A plant cell has a chloroplast and a big vacuole unlike the animal cell. The animal cell has a small vacuole and no chloroplast.
A cell wall is wall the surround the cell. The cytoplasm is a green pigment its what gives the plants it's green color. The chorolplast captured energy.
The Jobs of a cell is to make protein, make energy,and lastly make more cells
A stem cell is a cell that is capable of giving rise to indefinitely more cells of the same type.
3D Cell Model Project(Tyler Butler)
1. I made a eukaryotic cell called a plant cell and it is different from others because it is a square or rectangler shape and has a cell wall,which is a rigid layer lying outside the plasma membrane. A vacuole , which is a large water container and it also has centrioles, which is a cylindrical cell structure composed mainly of a protein.
2.Three Major Jobs that cells have are
Reproduction
Transport of Molecules
Conversion of Energy
3. A stem cell is an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. It comes from embryos which has about 150 cells.
3D Cell Model Project (Girnae Johnson)
1. I had made a prokaryotic cell. My cell is different from others because it has a chloroplast , cell wall, and a Large Vacoule. The cell wall is a structural layer that surrounds the cell outside the cell membrane. Chloroplasts works to convert light energy of the sun into sugars that can be used by cells. Lastly the Large Vacoule , the large Vacoule stores water and other substances.
2. The three basic functions of a cell are
Transport of Molecules
Conversion of Energy
Reproduction
3. A stem cell is a cell that mimics genetic information and it is located in the plant tissue
Cell cake(London Seace)
1. I made a plant cell cake which was re
ctangular just like a plant cell and it had all the organelles that a plant cells are supposed to have. A plant cell is different from a animal cell because it has a cell wall and a bigger vacuole it also has a centrosome in addition to the other organelles a plant cell also does not have lysosomes.
Centrosome :organizing center
Larger vacuole: to hold materials and waste
Cell wall: hold the structure and shape of the cell
2.A cells major job is to
•make protein
•make energy
•make more cells
3. The stem cells are located in the meristems and plant tissue
4. Stem cells in plants are used to recreate plants . It's like a process of cloning.
