Learning Objectives
1. Explain how the bodies of plants are structure and specialized to store food molecules and
reproduce.
- Plants are unique among the eukaryotes, organisms whose cells have membrane-enclosed nuclei and organelles, because they can manufacture their own food. Chlorophyll, which gives plants their green color, enables them to use sunlight to convert water and carbon dioxide into sugars and carbohydrates, chemicals the cell uses for fuel.
2. Explain how plants have adapted to allow for reproduction.
- Many possess vascular tissues for transport of water and nutrients and also the generations of plants have evolved
3. Identify and explain the reactions of photosynthesis.
- is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities. (google.com)
4. Describe the goals for genetic engineering of crop plants.
- Developing plant varieties expressing good agronomic characteristics is the ultimate goal of plant breeders. (http://isaaa.org/resources/publications/pocketk/17/default.asp)
5. Explain the basic steps creating a genetically modified organism.
- A. Isolate gene of interest
B. Insert gene into transfer vector
C. Plant transformation
D. Selection of modified plant cell
E. Regeneration into plants via tissue culture
F. Test plant performance

6. Evaluate the risks of genetic engineering in terms of safety, economy, effectiveness, and ethics.
- Harm a person's health, new allergens in food supply, antibiotic resistance, increased weediness, gene transfer to wild or weedy relatives, poisoned wildlife

Photosynthesis Lab
Gatorade vs Mountain Dew with spinach test and results
Question: Will spinach with Mountain dew or Gatorade with spinach go through more cellular respiration?
Hypothesis: The spinach leaves soaked in Gatorade will go through more cellular respiration due to a high O2 production
Materials: LabQuest, Bio Chamber, Gatorade, Mountain Dew, Beaker, Spinach leaves, Oxygen gas sensor, and CO2 Sensor
Procedure:
1. Cover the bottom of the bio chamber with spinach leaves
2. Pour the liquid to 50 in the beaker and then pour into the bio chamber
3. Connect the labquest sensor
4. Secure the lid on the chamber
5. Insert the CO2 sensor into one of the holes and the oxygen sensor in the other
6. Wait five minutes for the sensor to calibrate, then click to begin the 900 second data collection and record data
7. Clean and dry then put equipment away
8. Compare and analyze results
