WHAT A PLANT KNOWS: A FIELD GUIDE TO THE SENSES PDF, EPUB, EBOOK Daniel Chamovitz | 177 pages | 30 Apr 2013 | Scientific American | 9780374533885 | English | United States What a Plant Knows Quotes by Daniel Chamovitz Choice D is incorrect because it can be inferred from the passage that the advantage of multiple triggers is that they prevent the Venus flytrap from closing on the improper prey rather than from prematurely closing on the proper prey; the passage never implies that when touched by its proper prey, the Venus flytrap is at risk of closing too soon to capture it. The previous question asks what the Venus flytrap gains from requiring multiple triggers before closing. Instead, they describe how the hairs on the Venus flytrap function and how the system of multiple triggers works choices B and C and explain how the plant preserves a memory, as it were, that something has touched the trigger hairs choice D. Therefore, the tone that these phrases establish is best described as informal. Choices A, B, and D are incorrect because the phrases establish a tone that is informal, not academic choice A , melodramatic choice B , or mocking choice D. In the second paragraph lines , the discussion of short-term memory primarily functions to. The first paragraph describes the mechanism that prompts the Venus flytrap to close its trap. The second paragraph makes an analogy of each step of that mechanism to an aspect of short-term memory formation in humans and then poses questions about the precise physiological terms in which those steps are carried out. Choice B is incorrect because it is the third paragraph, not the second, that discusses the function of electric charges in the Venus flytrap; moreover, the passage presents this function as a fact, not as a controversial hypothesis. Choice C is incorrect because rather than stressing the differences between Venus flytraps and humans, the analogy in the second paragraph stresses their superficial similarities. According to the passage, which statement best explains why the Venus flytrap requires a second trigger hair to be touched within a short amount of time in order for its trap to close? Choice D is the best answer. Choices A and B are incorrect because the fourth paragraph explains that the second trigger supplements the action of the first trigger, not that it reverses it choice A or stabilizes its effect choice B. Choice C is incorrect because the third paragraph clearly states that the calcium channels open after the first trigger hair is touched, not the second. Choice B is the best answer. Choice D is incorrect because the last sentence of the fifth paragraph explains that the threshold for the time that can elapse between the touching of the first and second trigger hairs is twenty seconds, meaning that a large insect touching two hairs within ten seconds would almost certainly make the plant close. Based on the passage, in studying the Venus flytrap, Volkov and his colleagues made the most extensive use of which type of evidence? SAT Reading. SAT Writing Language.

The large black hairs on their lobes allow the Venus flytraps to literally feel their prey, and they act as triggers that spring the 10 trap closed when the proper prey makes its way across the trap. If the insect touches just one hair, the trap will not spring shut; but a large enough bug will likely touch two hairs within about twenty seconds, and that signal springs the Venus flytrap into action. If a small ant takes a while to get from one hair to the next, the trap will have forgotten the first touch by the time the ant brushes up against 25 the next hair. How does it 30 remember the first touch in order to react upon the second? Daniel Chamovitz If plants can see, smell, feel, know where they are, and remember, then perhaps they do possess some kind of intelligence. Maybe that is worth reflecting on the next time you casually stroll past a plant. Even a daffodil can detect when you're standing in its light, and a rhododendron knows when you're savaging its neighbor with the pruning shears. With deftness and clarity, Daniel Chamovitz introduces plants' equivalent of our senses, plus floral forms of memory and orientation. When you realize how much plants know, you may think twice before you bite them. This entertaining and educational book is filled with wondrous examples that underscore how the legacy of shared genomes enables plants and animals to respond to their environments. You'll see plants in a new light after reading What a Plant Knows. Chamovitz is a master at translating the science of botany into the language of the layman. After reading this book you will never again walk innocently past a plant or reach insensitively for a leaf. You will marvel and be haunted by a plant's sensory attributes and the shared genes between the plant and animals kingdoms. I commend this engaging text to all who wonder about life on earth and seek a compelling introduction to the lives of plants as revealed through centuries of careful scientific experimentation. It may come as a relief to vegetarians to learn that plants do not feel pain or suffer, in the human sense, when harvested. Nevertheless, after reading What a Plant Knows , we wanted to apologize to our daffodils for the times when our shadows have shielded them from the Sun. Covering touch, sound, smell, sight, and even memory, Chamovitz encourages us to consider whether plants might even be aware. A rare inside look at what life is really like for the grass we walk on, the flowers we sniff, and the trees we climb, What a Plant Knows offers us a greater understanding of botany and science and our place in nature. Additional Product Features Dewey Edition. Like us, a plant that aspires to win the rat race must exploit its environment. Even a daffodil can detect when you're standing in its light, and a rhododendron knows when you're savaging its neighbor with the pruning shears. With deftness and clarity, Daniel Chamovitz introduces plants' equivalent of our senses, plus floral forms of memory and orientation. When you realize how much plants know, you may think twice before you bite them. Backed by new research on plant biology, this is an intriguing look at a plant's consciousness. Chamovitz lets us see plants in a new light, one which reveals their true wonder.

What a Plant Knows: A Field Guide to the Senses (Paperback) | The Book Loft of German Village But now, in What a Plant Knows , the renowned biologist Daniel Chamovitz presents an intriguing and scrupulous look at how plants themselves experience the world—from the colors they see to the schedules they keep. Highlighting the latest research in genetics and more, he takes us into the inner lives of plants and draws parallels with the human senses to reveal that we have much more in common with sunflowers and oak trees than we may realize.
