Eukaryote- This is a plant cell because it has a cell wall and very large vacuoles for water storage. Plant cells also have chloroplasts which are used for photosynthesis to absorb energy from the sun.

Prokaryote- This is a bacterial cell because it does not have a nucleus. The genetic material is in the center but not surrounded by a membrane. It also has a cell wall just as a plant cell.

This is a prokaryote cell.

Muscle types. eukaryote- Eukaryote is an organism whose cells contain complex structures inside the membranes. A Eukaryote cell division is different than that of a prokaryote.It involves separating the duplicated chromosomes, through movements directed by microtubules.

Sydney This is a bacteria cell. It doesn't have a nucleus, so it's a prokaryot.

4. What do the cells do? Your body is made up of around 200 different types of cell, all working together, day and night. Each cell must make the molecules it needs to survive, grow, multiply and do its job. http://www.sciencemuseum.org.uk/exhibitions/lifecycle/122.asp Wikipedia.

=Elodea Cell= This is a picture an elodea cell. You can see the cell wall, chloroplasts, and the cell membrane. The size of each cell is 75 microns. 1.There both plant cells. The onion cell is almost twice the size of the elodea cell. They’re both rectangular. The elodea is can also be box like in shape.

2. The cell shrunk and this happen because it is a hypertonic solution. This happens because of osmosis.

3.What is an elodea? The elodea is a genus of aquatic plants and theory is often called water weeks. http://en.wikipedia.org/wiki/Elodea

This is a picture of an elodea cell after salt was put on it. You can still see the chloroplasts, cell wall, and cell membrane. The size of the cells is still 75 microns.

=Onion Cell= This is a picture of onion cells. You can see a nucleus, the cell wall, and a vacuole. The size of the of a single is 187.5 microns. 1) The onion cells are rectangular shaped. They are tightly arranged next to each other. 3) The purpose of adding iodine was so that the nucleus would be visible. 4) Q- Why are some cells bigger than others? A- Some cells are bigger than others because of available food and moisture. Sources: [] 5) When salt is added to a cell, the water rushes out of the cell due to osmosis, which is the diffusion of water. Water diffusion is how water moves from high concentrations to low concentrations to even water concentrations inside and outside of the cell. The cell would shrivel up and die because it would be a hypertonic solution, since there would be more salt outside of the cell than inside. It wasn't a hypotonic solution because that would be there is more salt inside the cell than outside.

=Cheek Cell= This is a cheek cell. You can see the cell membrane, the nucleus, and the vacuole. The cell's size is 37.5 microns. 1.The shape is circular. They are scattered in all directions. 2.The cheek cell is the only non-plant and non-rectangular cell of the three. It also has no cell wall. The onion and elodea cells have chloroplast. 3.What is a cheek cell? A cell that specifically makes up the cheek inside of your mouth. Cells have many different functions. These cells are like skin that is able to stay in your mouth and withstand saliva and food. http://wiki.answers.com/Q/What_is_the_importance_of_cheek_cells

=Cell Inquiry=

This is a picture of the apple slide. You can see the cell membrane, cell wall since it is a plant cell, and the nucleus. Some things may be hard to see because the stain of the drop.

This is a picture of the potato slide. You can see the cell membrane which is somewhat circular. You cant make out the components of the cell but you can see the outside of it.

Yes, fruits and vegetables are made of cells. This has to be true since all living things are made of cells. In order to prove this, we’ve conducted an experiment. Previous to this experiment, we had conducted other procedures on cells. We compared plant cells to human cheek cells to see the difference in shape. The plants we used were an onion and an elodea leaf. We saw that plant cells have a cell wall, chloroplasts and are rectangular or square, while animal cells are round with no cell wall. This relates to our experiment because if square or rectangular cells were seen, then you were looking at a plant cell.

=Cell Transport=

2. Why are diffusion and osmosis considered to be passive processes?

Osmosis is a specialized case of diffusion that involves the passive transport of water because it doesn’t require energy.

Because it does not require the input of any energy for it to take place. Diffusion is just the movement of particles from a region of higher concentration to a region of lower concentration, something they tend to do on their own.

3. Compare and contrast passive cell transport with active cell transport. You are responsible for discussing at least 3 similarities and/or differences. They are alike because they both transport. They are different because active requires energy to move material through a cell membrane and the passive does not require energy. Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more too less. Active transport occurs in the opposite direction, from less too more. They both have the job of transporting a substance across a membrane and the change in concentrations on different sides of a membrane. Both are crucial to the function of a cell. Another difference between the two is that active transport requires a special protein to make the transport occur. Passive does not need this.

4) Why does it take longer for water to diffuse in different objects of the same size? The equation for figuring out diffusion is //t= x2// ///2D//. D is the diffusion coefficient of a solute in a free solution. X is the mean distance traveled by the diffusing solute along one axis after elapsed time //t//. T is the elapsed time since diffusion began. Knowing this, you could perform an experiment with different kinds of objects that are of the same size and shape and soak them in a colored solution for the same amount of time. Whichever was diffused through the furthest would be the solution that a solution can diffuse through the easiest.

Brody Morgan Period 7 Garrett Neal and Brody Morgan DNA AND RNA

DNA is a coil like matter. It is also like a ladder. DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide. Two DNA strands form a helical spiral, winding around a helix axis in a right-handed spiral The two polynucleotide chains run in opposite directions The sugar-phosphate backbones of the two DNA strands wind around the helix axis like the railing of a spiral staircase.

DNA is the blueprint of life. It dictates eye color, bone structure, blood type, basically everything about you. You get one half of your genome from your mother's egg cell and the other half from your father's sperm cell. This blueprint then controls how you, as an embryo develops, and further down, how you as a baby will also develop. The purpose of DNA is to not only control development, but it is also pass down information as well. Most advantages in the genome will be passed down to the next descendant, causing the general population to eventually evolve, providing life with ever-changing beings. DNA controls the structure and function of the entire body. It’s in every cell. It contains genes that control protein production. The proteins they get shipped to there appropriate destination in the body.
