Textbook Question
Chapter 39, Problem 10TYU
SCIENTIFIC INQUIRY A plant biologist observed a peculiar pattern when a tropical shrub was attacked by caterpillars. After a caterpillar ate a leaf, it would skip over nearby leaves and attack a leaf some distance away. Simply removing a leaf did not deter caterpillars from eating nearby leaves. The biologist suspected that an insect-damaged leaf sent out a chemical that signaled nearby leaves. How could the researcher test this hypothesis?

A biologist finds that a plant is being attacked by beetle larva, which eats flowers. Later that same day, she observes that the air around the plant has an unusual "chemical" odour. Next day, she sees that there are many wasps stinging the caterpillars on the flowers. Give the most likely explanation for this observation and explain the underlyingconcept clearly.
Using scientific concepts and terms describe how the Bucket Orchid can temporarily “hold” onto the bee’s body while it glues the pollen sacs to the bees back. In other words, what type of plant “movement” (aka. response) would this most likely be described as? Please watch the YouTube link to answer the question.

- Some 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). Based on this scenario, please answer the following questions: a) What is the…arrow_forwardIn your own words - grasses are flowering plants but many do not have colorful flowers.

A new herbicide targets the function of guard cells and prevents them from becoming flaccid and closing the stomata. What effect would the herbicide have on plants? a.Plants would dry out because guard cells protect the epidermis against desiccation. b.Plants would be eaten because guard cells protect leaves against herbivores. c. Plants would dry out because stomata would not be able to close. d.lt would regulate the intake of minerals in the plants.arrow_forward

- Experiment to test how one of the following variables impacts the growth of Brassica rapa: Water, Nutrient Availability, and Herbivory 1) Be thorough, how would you set up an experiment of Brassica rapa? For example, if you plan to decrease the amount of water given to your plants how you would like to do this? If you plan to increase nutrients, think about whether you want to do this once or weekly. If you plan to simulate herbivory, think about how you will do this and how much leaf tissue you want to remove. 2) What variables will be controlled during your experiment? In other words, what variables will be the same across the two groups?arrow_forwardWe say that movement is a characteristic of living organisms but we always don’t see visible movements in plants.
