About Course

For centuries we have collectively marveled at plant diversity and form—from Charles Darwin’s early fascination with stems and flowers to Seymour Krelborn’s distorted doting in Little Shop of Horrors. This course intends to present an intriguing and scientifically valid look at how plants themselves experience the world—from the colors they see to the sensations they feel. Highlighting the latest research in genetics and more, we will delve into the inner lives of plants and draw parallels with the human senses to reveal that we have much more in common with sunflowers and oak trees than we may realize. We’ll learn how plants know up from down, how they know when a neighbor has been infested by a group of hungry beetles, and whether they appreciate the music you’ve been playing for them or if they’re just deaf to the sounds around them. We’ll explore definitions of memory and consciousness as they relate to plants in asking whether we can say that plants might even be aware of their surroundings. This highly interdisciplinary course meshes historical studies with cutting edge modern research and will be relevant to all humans who seek their place in nature. This class has three main goals: 1. To introduce you to basic plant biology by exploring plant senses (sight, smell, hearing, touch, taste, balance). 2. To introduce you to biological research and the scientific method. 3. To get the student to question life in general and what defines us as humans.

Course Syllabus

This week we start a systematic review of a plant's sensory systems by starting with plant responses to light. We will cover an overview of human vision, plant responses to light, Darwin's experiments showing plant responses to light, phototropism, phytochrome and flowering, and modern research on phototropism. In other words, this week we get into more advanced concepts in plant sensory biology. The last module is especially advanced, and will be clearer for those of you with a strong biology background. But do not fret, aside from very basic concepts, this module will NOT be included in the exam (you will not be responsible for understanding the intricacies of the experimental methods, etc.). If you have not already, please review the Course Syllabus for general information about this course.

Course Introduction

Understanding Plants - Part I: What a Plant Knows This course is Part I of a series that explores the meaning of plants, and why we care about them so much. In this course we cover a broad range of topics, including plant biology, plant pathology, common garden pests and diseases, crop rotation and other aspects of plant care. We’ll also cover some myths and misconceptions that often surround plants, and we’ll discuss how we can tell how well a plant is cared for. By the end of this course, you’ll understand what makes plants tick, and how to give them the care they deserve. This course will introduce you to some of the most basic concepts of plants, and you’ll learn a lot about what makes plants tick. We’ll cover topics such as: What a plant sees and experiences: vision, smell, touch, hearing, hearing loss, nervous system, stress, appetite, thirst, stress response, stress management, problems in the body, sunlight, soil and water quality, water resources, urban and agricultural pests, diseases and problems, and the importance of proper care. What a plant eats: carbohydrates, sugars, proteins, water, nutrients, calcium, potassium, magnesium, phosphorus, acids, and alkalinity. What a plant dislikes: cold, strong odors, damp, inedible plant matter, and pesticides and herbicides. What a plant knows: how to say no, defend against those

What a Plant Knows What a Plant Knows is a 2012 popular science book discussing the sensory system of plants.
What No Man Knows What No Man Knows is a 1921 silent film drama produced and directed by Harry Garson and starring Clara Kimball Young.
Thermogenic plant Thermogenic plants are also protogynous. This means that the female part of the plant matures before the male part of the same plant. This reduces inbreeding considerably. The only way the plant could get fertilized is from receiving pollen from different plants. This is why thermogenic plants release pungent odors to attract flies.
Plant The study of plant uses by people is termed economic botany or ethnobotany; some consider economic botany to focus on modern cultivated plants, while ethnobotany focuses on indigenous plants cultivated and used by native peoples. Human cultivation of plants is part of agriculture, which is the basis of human civilization. Plant agriculture is subdivided into agronomy, horticulture and forestry.
Heaven Knows What "Heaven Knows What" received positive reviews from critics. On Rotten Tomatoes, the film has a rating of 84%, based on 56 reviews, with a rating of 7.6/10. The site's critical consensus reads, "Grueling and rewarding in equal measure, "Heaven Knows What" hits hard -- and serves as a powerful calling card for its captivating star, Arielle Holmes." On Metacritic, the film has a score of 75 out of 100, based on 22 critics, indicating "generally favorable reviews".
On Plants The first part discusses the nature of plant life, sex in plants, the parts of plants, the structure of plants, the classification of plants, the composition and products of plants, the methods of propagation and fertilization of plants, and the changes and variations of plants.
Plant morphology The detailed study of reproductive structures in plants led to the discovery of the alternation of generations, found in all plants and most algae, by the German botanist Wilhelm Hofmeister. This discovery is one of the most important made in all of plant morphology, since it provides a common basis for understanding the life cycle of all plants.
Nobody Knows What You Do Nobody Knows What You Do is an album by John Hartford, released in 1976.
On Plants The second part describes the origins of plant life, the material of plants, the effects of external conditions and climate on plants, water plants, rock plants, effects of locality on plants, parasitism, the production of fruits and leaves, the colors and shapes of plants, and fruits and their flavors.
Plant physiology Fourthly, plant physiologists study the ways that plants control or regulate internal functions. Like animals, plants produce chemicals called hormones which are produced in one part of the plant to signal cells in another part of the plant to respond. Many flowering plants bloom at the appropriate time because of light-sensitive compounds that respond to the length of the night, a phenomenon known as photoperiodism. The ripening of fruit and loss of leaves in the winter are controlled in part by the production of the gas ethylene by the plant.
California Native Plant Society The California Native Plant Society (CNPS) is a California environmental non-profit organization (501(c)3) that seeks to increase understanding of California's native flora and to preserve it for future generations. The mission of CNPS is to conserve California native plants and their natural habitats, and increase understanding, appreciation, and horticultural use of native plants throughout the entire state and California Floristic Province.
Plant virus More recently virus research has been focused on understanding the genetics and molecular biology of plant virus genomes, with a particular interest in determining how the virus can replicate, move and infect plants. Understanding the virus genetics and protein functions has been used to explore the potential for commercial use by biotechnology companies. In particular, viral-derived sequences have been used to provide an understanding of novel forms of resistance. The recent boom in technology allowing humans to manipulate plant viruses may provide new strategies for production of value-added proteins in plants.
What No One Knows What No One Knows () is a 2008 Danish political thriller film written and directed by Søren Kragh-Jacobsen, and starring Anders W. Berthelsen, Maria Bonnevie, Ghita Nørby, and Lars Mikkelsen. The film was produced by Nimbus Film.
Narva Oil Plant The oil shale retorting plant (the UTT-3000 refinery) was built in the late 1970s next to the Eesti Power Plant to provide shale oil as a start-up fuel for the power plants. The plant was commissioned in 1980. Since the beginning of the 1990s, the oil plant operated as a part of the Narva Power Plants. In September 2007, the oil plant was separated from the power plants and the separate subsidiary of Eesti Energia was established.
Plant arithmetic Plant arithmetic is a form of plant cognition whereby plants appear to perform arithmetic operations - a form of number sense in plants.
What the Night Knows This novella was written for the Kindle, and saw print in the paperback edition of the novel. It is mainly set prior to the incidents in "What The Night Knows", but also bookends the novel itself. In the initial part of the novella, Alton Turner Blackwood meets a boy named Howie, and the subsequent events of this novella dovetail into the background of the main novel, with a time lapse to the end of the novel.
Plant Land plants are key components of the water cycle and several other biogeochemical cycles. Some plants have coevolved with nitrogen fixing bacteria, making plants an important part of the nitrogen cycle. Plant roots play an essential role in soil development and prevention of soil erosion.
Plant morphology Understanding which characteristics and structures belong to each type is an important part of understanding plant evolution. The evolutionary biologist relies on the plant morphologist to interpret structures, and in turn provides phylogenies of plant relationships that may lead to new morphological insights.
Native plant Native plants form a part of a cooperative environment, or plant community, where several species or environments have developed to support them. That could be a case if a plant exists because a certain animal pollinates the plant and that animal exists because it relies on the pollen as a source of food. Some native plants rely on natural conditions, such as occasional wildfires, to release their seeds or to provide a fertile environment in which their seedlings can become established.
3S Understanding The paradigms are revisited when Henderson talks about standards. Standards are an important topic in education and seeing the Transformative Standards he puts forth shows them in a new light. Received standards stress the importance of “standardized factual knowledge and skills, knowledge and skills that are testable with a large population, and criteria based on a predetermined metric based on counting”. These standards are not based on the students or what they have learned. Henderson’s Transformative Standards are based on student understanding and wisdom. Taking what the student knows of the subject and allowing them to show their understanding through demonstration and performances.
