Question
Chapter 37.2, Problem 2EQ
Summary Introduction
To determine: Whether four seedling tips are enough to conclude the general response of such seedling tips in the experiments performed or not.
Introduction: An organism’s response to an external or an internal stimulus is known as its behavior. Plant movement is one of the examples of plant behavior. Chemical signals which are transported within the body of a plant are known as plant hormones. Some of the examples of plant hormones are auxins, cytokinins, gibberellins, ethylene, abscisic acid, and brassinosteroids.

- The data that is attached below was collected during a lettuce seed ecotoxicity assay. Lettuce seed assays are used to compare the ecotoxicity of methanol, ethanol, and isopropanol by these alcohols' effects on germination rate and root elongination. Using the attached data, help answer which alcohol seems to be the most toxic to lettuce seeds. Why or why not would your results be expected? What does this information tell you about using ecotoxicity data to estimate human toxicity?arrow_forwardA team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 μmol, and Groups 3 and 4 were exposed to 500 μmol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below. Group 1(200 μmol, no P) Group 2(200 μmol, + P) Group 3 (500 μmol, no P) Group 4 (500 μmol + P) Average Dry weight (g) 0.8 1.1 1.5 6.2 Describe the effects of light and phosphorous on the growth of the plants in this study. Explain how the metabolic processes associated with the plant kingdom likely influenced these results.arrow_forwardUnder which of the following conditions would pollen from an S2S5 plant successfully pollinate an S1S5 flower? a. Using pollen from a carpelate flower to fertilize a staminate flower would be successful. b. If the plants used gametophytic self-incompatibility, half of the pollen would be successful. c. If the plants used sporophytic self-incompatibility, half of the pollen would be successful. d. Pollen from an S2S5 plant can never pollinate an S1S5 flower.arrow_forward
