Mitosis Experimental Design
I. Problem/Question
According to page 258 in the California Prentice Hall Biology Textbook, number 28 gives us a question explaining that a student in class believes that temperature can have an affect on the rate of mitosis in plant cells. Below, I have designed an experiment to test the hypothesis given and provided my own hypothesis along with the results I would expect to see.
II. Hypothesis
I believe that temperature may affect mitosis and if I'm correct, I will see an increase in the amount of cells when it gets hot and decrease when it gets cold as
measured by the height of the plant.
measured by the height of the plant.
III. Variables

IV. Experimental GroupsExperimental group: experimental groups can be the temperature where the plants are placed. Example: desert-like environment, 5 degrees Celsius hotter than ideal temperature, and an environment with ideal temperature.
Control groups: a control group can be that the plants are all the same species and in a greenhouse in an ideal temperature. |
V. Experimental Procedure
- Make three groups, each group containing five plants. Make sure the plants are all the same species.
- Isolate all three groups by placing group one in a 5 degree Celsius environment hotter than ideal. Put group two in ideal temperature, and put group three in an environment 5 degrees Celsius colder than ideal.
- The plants will be watered everyday, as recommended.
- Observe and record any changes seen. Measure the height of the plant once a day (mornings) for six weeks.
VI. Materials List
- Water
- Ruler for measuring the plants
- Same brand of soil
- Fifteen of the same plants for experimentation
- Pencil and paper for recording observations
- Three locations with the three different types of temperatures
VII. Expected Results
I would expect to see the amount of cells increase in the plants that are in 5 degrees Celsius hotter than ideal temperature because temperature can affect mitosis.
If my hypothesis that temperature will affect mitosis is true, I will see the amount of cells in the plants increase due to the 5 degrees Celsius hotter than ideal temperature as measured by the height of the plant and it being taller than those in the ideal and 5 degrees Celsius colder temperature.
