Chapter 35, Problem 16

The carnivorous plant Nepenthes bicalcarata ('fanged pitcher plant') has a unique relationship with a species of ant—Camponotus schmitzi ('diving ant'). The diving ants are not digested by the pitcher plants, but instead live on the plants and consume nectar. Diving ants also dive into the digestive juices in the pitcher, swim to the bottom, and capture and consume trapped insects, leaving uneaten body parts and ant feces behind. What nutritional impact do the ants have on fanged pitcher plants? Do the pitcher plants derive any nutritional benefit from this relationship? Carnivorous plants and legumes (e.g., peas, soybeans) both absorb key nutrients directly from other organisms. How is nutrient acquisition in pitcher plants similar to that in legumes? How is it different?

Hello everyone here We have a question asking us to identify the correct similarity between a picture plant and a pea plant. A pitcher plant is a carnivorous plant. A pea plant is a lagoon, so our first answer choice is a Both are carnivorous plants. This is incorrect. Only the pitcher plant is carnivorous. Be bacteria grow in the root nodules of both plants, bacteria only grow in the root nodules of lagoons, which would be the pea plants. So B. Is incorrect. See the primary nutrient that both types of plants typically absorbed is nutrient. Both pitcher plants and P plants acquire nutrients from soil or directly from other organisms. Nitrogen tends to be the key nutrient absorbed from other organisms or the soil in both plants. So C. Is correct. D both plants capture insects and digest them to obtain nutrients. This is only the picture plant. So our answer here is C. Thank you for watching. Bye.

Textbook Question

There is a conflict between van Helmont's data on willow tree growth and the data on essential nutrients listed in Table 36.1. According to the table, nutrients other than C, H, and O should make up about 4 percent of a willow tree's mass. Most or all of these nutrients should come from soil. But van Helmont claimed that the soil in his experiment lost just 60 g, while the tree gained 74,000 g. Calculate the percentage of the added mass accounted for by soil, and compare it to the predicted 4 percent. State at least one hypothesis to explain the conflict between expected and observed results. How would you test this hypothesis?

Nitrogen is a key nutrient often obtained by carnivorous plants from the insects they digest. Are the results presented here what would be expected if nitrogen is a limiting nutrient? Explain.
