Cells

Michael. Gianna, Noelle;
 * Hypothesis:** If a,b and c have cells they all must be living. Then a and b only shows the characteristics of a living organism

Cells are defined as living organisms. All living things are composed of one or more cells. There is unicellular and multicellular organisms. Unicellular consists of one cell, while multicellular consist of many cells.
 * Characteristics**: needs energy: sunlight, glucose (sugar), water. Cells have structure, functions, they reproduce, and have DNA.
 * Protocol**: We could take a cell from a living thing and observe the behavior of how it reacts to a stimulus under neath a microscope. Keep the cell underneath the microscope and see if it is a multicellular or unicellular organism, while seeing its structure.


 * Materials**:

Several particles of Substance A, B and C. Microscope slides Cover slip 50 mL of water Microscope Eyedropper


 * Procedures:**

1. Set up your microscope. 2. Take several particles of a substance and place it on a microscope slide. 2. Place one-two drops of distilled water on the substance, to create wet mound. 4. Then place the cover slip on top of the substance. 5. Observe under the microscope. 6. Repeat for the other two substances.


 * Observations:**
 * Substance A:** Looks like brown specks. 3 different shades of brown. All look almost the same except for two black circles in the center.
 * Substance B:** Too much of the substance combined with water, turns into a liquid.
 * Substance C:** Doesn't look to be living because the Substance C is dark, not moving and **i**sn't made up of cells**.**


 * Conclusion:**

Since Substance B was the only one that react to the stimulus, Substance B is the only living substance between the three.

Substance A:



Substance B:



Substance C:
