CONCLUDING REMARKS

Based on our observations and tests, we predict that this plant uses UV patterns to lure insects into its trap. We predicted that the bulb near the opening of the trap may have some type of nectar to attract prey, but we were unable to test this. The hairs inside the trap grow downward making it difficult for the insect to crawl out. The liquid in the bottom of the trap is highly basic, and dissolves the prey. Since the traps are pretty small, it makes sense that the prey would also have to be small. UV patterns to attract and trick insects  small hairs pointing down to guide the insect into the trap and make it hard for them to climb back up

TESTING FOR PH

The pH of our plant was an average of 10. A pH of 10 means that the plant tested more basic than acidic. We got our pH through testing the liquid that was inside of the main leaf of the plant. Most plants have a pH of 5.5, so a pH of 10 is more basic than usual. The pH of a plant varies by the type of plant and the environment it lives in. Roots will take in either more acid or more basic substances depending on the food available, the temperature of roots, or intensity of light. Photo by Emma Cain

MORPHOLOGICAL DATA

Qualitative Observations: Plant is green, purple, and brown. Traps contain small hairs on the outside and the inside. A portion of the plant appears to be dead The traps all grow out from one point Quantitative Observations: There are four main traps The alive trap (tallest) is 6.5 cm tall. Photo by Emma Cain

TESTING FOR SUGAR

               We predicted that our plant might use sugar to attract prey, so we tested for monosaccharides. We cut off part of the main leaf to test, but the test turned out negative. We predicted the the bulb at the top of the leaf may have contained sugar for the insects, but decided not to test in case removing the bulb would harm the plant. Photo by Emma Cain

UV IMAGES

Our plant had UV marking on the inside leaf that is shaped like a cup. UV can be used for growth and trigger colorful petals and leaves. Our plant having UV markings lead us to believe that the UV is a critical part of attracting prey. UV markings are vital to some carnivorous plants. Insects that see in UV are attracted to plants with special UV markings. Our plant uses UV to trick insects, especially pollinators, that think their strip of UV light leads to food. They mirror the patterns of flowers that use UV to attract insects to pollinate them. Photo by Emma Cain
