Question
Chapter 39.1, Problem 3CC
Summary Introduction
To predict: Whether Viagra will be helpful in occurrence of normal de-etiolation in leaves of aurea mutant tomato.
Concept introduction:
In de-etiolation process, the first step is the reception of signals from the light. This reception is done by phytochrome that is present in the plasma membrane. This phytochrome acts as a first messenger that initiates the de-etiolation.

Tens of thousands of such compounds have been discovered, and he estimates that in the United States adults eat about 1.5 g of these compounds each daylevels that are approximately 10,000 times higher than those of the synthetic pesticides present in the diet. For example, cabbage contains 49 natural pesticides and metabolites, and only a few of these have been tested for their carcinogenic and mutagenic effects. a. With the introduction of new foods into the U.S. diet over the last 200 years (mangoes, kiwi fruit, tomatoes, and so forth), has there been enough time for humans to develop resistance to the mutagenic effects of the toxins present in those foods? b. The natural pesticides present in plants constitute more than 99% of the toxins we eat. Should diet planning, especially for vegetarians, take into account the doses of toxins present in the diet?arrow_forward

Plants use CO for 2 photosynthesis, and laboratory studies suggest that increasedCO2 levels could cause a rise in photosynthetic activity. However, as one environmentalist noted, What plants do in environmental chambers may not happen in nature, where there are many other interacting variables. Strictly from the standpoint of physiological effects, what are some possible ramifications of a rapid doubling of atmospheric CO2 on plants in temperate environments? In arid environments?arrow_forward15. The sticky cinquefoil (Potentilla glandulosa) is a small, deciduous plant with bright yellow flowers that lives throughout the American West, and its leaf phenotype can vary depending on environmental conditions. Inland, where there are dramatic seasonal temperature swings and unpredictable droughts, plants shed their large “summer leaves” in autumn when the temperature begins to drop. In the spring new leaves are smaller and develop in a compact rosette. This phenotype persists for several months and is thought to be an adaptation that makes the plants drought-resistant (because less water evaporates from reduced leaf surfaces). By contrast, the leaves of P. glandulosa plants growing in a coastal climate are always large. In their habitat, seasonal temperature swings are not as great and the annual cycle of winter rain and summer drought is highly predictable. Suppose you decide to explore the hypothesis that the coastal population is genetically capable of exhibiting the same seasonal shift in leaf morphology as the inland plants. Would you need access to a greenhouse where you can control variables, or would it be just as easy to do experiments in the wild? Explain your reasoning and outline your experimental design—including the variable or variables you will test in the first experiment.arrow_forward
