Morphological Data

Image
This tube-like structure is how our plant traps its prey. The first time we observed the plant, we found a small bug (about 4 mm) drowning within a sticky liquid at the base of the interior of the tube. The tube itself is 7 centimeters tall and about 2 centimeters wide.

Conclusion

Based on our research, we believe this plant lures prey through the contrasting colors present on the tubes. The tube is green with contrasting red dots, which may lure prey to it. When tested under a UV light, we found that the red dots emitted the unique purple light. These contrasting colors and light properties may be responsible for luring prey. The plant most likely traps the plant inside the tube, possibly with the sticky coating it possesses. Looking at the pH of the liquid found inside the tube, we can guess that it kills and digests its prey in the tube with the liquid. It is extremely acidic, and burned our teacher's hand when she touched it. Based on this, we believe that whatever prey this plant catches would be killed very quickly. The size of the tube lead us to believe that the prey of this plant is primarily small insects no longer than one centimeter long. When we first saw the inside of the tube, there was an insect of about that size floating dead in the liqui...

Sugar Tests

We removed some of the liquid from the plant tube, then put it on a slide. The slide was placed on a hot plate and heated up. The color of the liquid did not change, indicating that there was no sugar present. If there were sugar, the color would have turned a different color.
