Chapter 38.1, Problem 3R
Summary Introduction
To review:
The responses of the plant when a researcher makes a small cut in the plant’s leaf and apply salicylic acid at the site of the incision.
Introduction:
Salicylic acid (C7H6O3) is a phenolic acid, which is colorless, crystalline, and acts as a plant hormone. The production of salicylic acid is activated by both general and specific immunity and protects plants from pathogens.

Before being treated with 50 percent Clorox for 20 minutes, all explants were properly cleansed with distilled water. After that, the explants were washed with distilled water before being cultivated on Murashige and Skoog (MS) basal medium plates.For each type of explant, a total of five plates were created, each with ten explants. Table shows the findings obtained after a week. Discuss and draw conclusions from the findings.arrow_forwardGrowers often wrap potted plants in plastic sleeves prior to shipping.

Use fully annotated diagrams to support your answer.

One version of this device, called a leaf chamber, is shown below. When a scientist uses this device on a plant, they don’t need to break the leaves off the branch or stem they are attached to. The leaf chamber makes an airtight seal around the stem or branch even though it is sticking out of the chamber. Using this device, scientists detected the most change in O2 and CO2 levels inside the chamber when a leaf is in the chamber. They only detected a small change in O2 and CO2 levels in the chamber when a green stem was placed in the chamber. No change was detected when a root or a brown stem was placed in the chamber. Why do you think a scientist would prefer not to remove the leaves from a tree or a plant in order to take these sorts of measurements?arrow_forward
