Question
Chapter 19, Problem 13WIO
Summary Introduction
To determine:
The reason it might be advantageous for the plant to prevent mammals, but not birds from eating its fruits. The spurge-laurel is a species of shrub that produces berries and causes internal bleeding and death in humans but is harmless for the birds.
Concept introduction:
The spurge laurel shrubs are the species having poisonous contents in their berries, especially in the sap, bark and stem. The seeds of berries are dispersed by birds in different areas.

Some angiosperm species have exclusive relationships with just one species of pollinator. How would this relationship benefit the plant? What are the risks to the plant?
Bees do not eat pollen. They only inadvertently transport pollen to pollinate angiosperms.

- Another issue for these trees is fire. Giant redwood trees are very adapted to tolerate fire. The mature trees have thick bark which helps them survive most fires. Younger trees are still at risk. The seeds can remain dormant in cones for many years (estimated 20) and germinate best after the cone is exposed to fire. However, highintensity fires (hot temperatures) are risky for seeds and trees of all ages. What are two things you could do to try and mitigate (reduce) the risk of fire damage but still allow for good seed germination in forests?arrow_forwardThe immature fruit of the opium poppy produces many chemicals that affect animal nervous systems.

- As you learned in this chapter, many prescription drugs are derived from natural plant products. Numerous other plant substances, including caffeine and nicotine, have effects in the human body, as well. There is also a wide array of plant products, in the form of pills, powders, or teas, marketed as herbal medicines. Some people prefer taking these “natural” products to pharmaceuticals. Others use herbal supplements to boost energy, promote weight loss, strengthen the immune system, relieve stress, and more. The U.S. Federal Drug Administration, which approves pharmaceuticals, is also responsible for regulating herbal remedies. What does the label “FDA-approved” on an herbal remedy mean? How does that compare to FDA approval of a drug? The FDA website http://www.fda.gov/ForConsumers/default.htm is a good place to start your research. (Note that the FDA classifies herbal remedies as dietary supplements.)arrow_forwardUnripe fruits are hard and tart. Ripening is a process that sweetens and softens the fruit to make it more attractive to animals who will eat the fruit and disperse the seeds. A plant hormone, ethylene, leads to the ripening of many fruits. Once ethylene starts being pro- duced, it initiates a feedback loop that causes more ethylene to be produced, increasing the rate of ripening. Which of the following best identifies and describes the feedback loop initiated by the pro- duction of ethylene? A It is a positive feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. B с D It is a negative feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus. It is a negative feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. It is a positive feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus.arrow_forwardWhat is the purpose of the fruit we (and other animals) eat, from the plant's perspective? Group of answer choices To create something attractive to pollinators. To create a food item that ensures humans will continue to farm them. To bring in more than one type of pollinator. To entice us to eat the seeds contained inside the fruit, and thus disperse the seeds.arrow_forward
- A slight change in a plant species’ flower structure might favor a different pollinator. How might such a change in flower structure lead to a new plant species? How does coevolution between flowering plants and animal pollinators help explain the huge diversity of angiosperms?arrow_forwardSome plants in wetter climates release certain chemicals in response to leaf consumption by insects. These chemicals may either repel the leaf-eaters and/or attract other insects that will consume the leaf-eaters. A researcher was interested in whether desert plants emitted the same types of compounds. Desert plants have different kinds of leaves compared to plants from less arid areas. The researcher harvested Coville’s lip fern (Cheilanthes covillei) from deserts in Utah to bring into a greenhouse. The plants were 12 – 15 cm (5 – 6 in) tall. Each plant was placed in a separate pot, and there were 40 pots in all. Each pot was assigned to one of four “leaf eater” treatments: a control (i.e., no insects); 5 hornworms; 5 leaf bugs; or 5 flea beetles. Then the researcher measured the emission rate of a particular repelling compound from each plant once every hour for a total of 8 hours (8:00 am – 4:00 pm).
