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.

Introduction
Welcome to "What a Plant Knows (and other things you didn't know about plants)". If you have not already, please review the Course Syllabus for general information about this course.
What a Plant Sees?
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.
What a Plant Smells?
This week we continue our systematic review of a plant's sensory systems by exploring responses to volatile chemicals (in other words, what a plant smells). We start with an overview of the plant cell, briefly review human olfaction (smell), and then explore how fruits know when to ripen. From there we go over three different experiments that explore plant responses to volatile chemicals and start exploring the controversial question, "Do plants communicate with each other?".
What a Plant Feels?
This week we continue our systematic review of a plant's sensory systems by exploring responses to tactile stimulation (in other words, what a plant feels). We start with an overview of the mechano-sensory system that differentiates between different tactile stimulations, briefly review the way electricity is used in neural communication, and then explore how the Venus flytrap knows when to close, and what powers the opening and closing of the Mimosa leaves. We'll learn how plants change their structure to cope with windy conditions, and go over some of the rather complex biology that is involved in the genetic response in plants to being touched. I'll let you know what I think of the question, Do plants feel pain? And then we'll try to understand whether plants hear, and if they do, which music they prefer.

Love the clarity of the instructors deliver which is supported by great explanations and most importantly visual aids & demonstrations. Ps... Especially loved the bloopers at the end. Nice treat! :)
A perfect course to understand all senses of plants in a straightforward way and I must admit the way professor Daniel chamovitz helped me to better acknowledge this course was satisfactory for me.
So far, I'm really enjoying this course. I like the look of it, the professor is engaging and as a layperson I find the content very, very interesting. What a wonderful take on plant biology!
Great course - the professor is enthusiastic, engaging, and teaching complex concepts in a way that makes them easy to understand and remember, even for someone with no biology background.
I started this course with very little knowledge of biology and finished it with a solid foundation in plant biology. I'd recommend it to anybody wanting to learn more about plants.
Daniel Chamovitz is a very good teacher, the material is a clearly presented. There is also a lot of discussion of experiments which underpin the ideas in the course in a nice way.
This was a great course! I loved learning about plants which to be honest i knew very little before completing this course and now I am very well informed and want to know more.
Daniel is a great teacher and he can make complex things easier for understanding, and the course in general intrigues you to continue exploring the wonders of a 'plant world'
the information presented is relatable and makes total sense-largely due to Proffessor Chamovitz' explanations. I thoroughly enjoyed this course, can't wait for part two!
Professor Daniel Chamovitz was wonderful and very interesting. But it was difficult for me as I have very little preliminary information on plants and biology
A great study and very enjoyable.\n\nPlants are food for thought as well as the table; who would have thought it.\n\nThanks for creating this course !
Amazing course, explaining plant evolution on molecular biology level, showing differences and similarities with animal kingdom with amazing clarity.
I think the tests were a bit difficult and the fact that many students taking this course aren't native speakers should be taken into consideration.
Este curso es muy claro. Comienza con los más sencillo y va subiendo poco a poco el nivel de la información.\n\nEntretenido, completo y estimulante.
love it so far. Its informative and fits my schedule. i love that i can watch the videos as much as needed to learn, and that doesnt put anyone out.
This is a great introductory course to Plant Genetics! Be sure to take notes so that you can easily answer the final quiz by the end of the course
I love the content and the instructor. Well put together and easy to understand. I highly recommend for anyone interested in the subject!
This is an informative and enjoyable course by a professor who is passionate about his work and who cares about the world around him.
Wonderful course - Dr. Chamovitz is an excellent teacher with extensive knowledge on the subject and an approachable teaching style.
This course was just awesome and specially the professor is so cool and his method of teaching was so awesome really appreciated...
