| Explore | We understand process photosynthesis and understand that plants both need and produce glucose which is the main idea of photosynthesis. We also know that the plants need sunlight, CO2, O2, H2O, Nutrients which is found within the soil. Some plants can produce fruits while others don ´ t. They can also adapt to different environments in order to survive like how some plants in the desert can survive off of little amounts of water. |

| Research Question | Do traits that are the most common benefit the plant? How are the plant genes affected by the environment and life cycle? Such as color and length We came up with this research question based on our activities outside and our brain storming questions prior. |
| Predictions | we think that if our high fertilizer were to grow we believe it would have grown faster than the low fertilizer did and since we replanted hopefully soon enough we ´ ll know for sure. The reasoning behind this is because fertilizer improves the supply of nutrients in the soil, directly affecting plant growth. |
| Experimental Design | We will test how the nutrients affect the plant by having a control and test variable, control being low fertilizer and test being high fertilizer. However, UV lights, temperature, CO2, and H2O will be in constant conditions. |
| Conclusion | Can phenotypes be affected by a changing environment? Yes, from our 2 sets of plants we have seen a big difference between the high fertilizer and low. We predicted that since fertilizer supplies nutrients and the soil and roots help retain water it would help the plant be healthier and live longer. We can see that with our high fertilizer that it did in fact live longer and healthier. After all our results we can see the plant's genes are also affected. This is because there is so much nutrients in the high fertilizer that it turns off the original/ inherited genes from our F2 generation plants. This shows that the environment in which it contains so much protein, affects the genes which then affects the phenotype, the traits. We can see that with most of our graph data for instance the leaf and stem ratio. We see that the low fertilizer ( normal environment ) has more Purple Stem and Green leaves than the high fertilizer. While in the high fertilizer it has more Green leaves and Green stems, therefore proving our conclusion. |
