Professor Catherine Kleier – Plant Science: An Introduction to Botany

If you look around right now, chances are you’ll see a plant. It could be a succulent on your desk or grasses and shrubs outside your front door or trees in the park. It could be a close-knit friend. to The plants are prone to wilting to make us happy, even if we don’t notice, offering unique pleasures and satisfactions. And of course without plants, we wouldn’t even be here: Not only do plants produce oxygen, they also produce their own food—the food that directly or indirectly supports us and all animal life on the planet.

There were 24 lectures. Plant Science: An Introduction to Botany, Dr. Catherine Kleier We are invited into the unique world of plants and the joy of learning and celebrating the secrets of living nature. Dr. Kleier shares her tremendous depth of knowledge with contagious excitement for her subject—supported by fascinating graphics and in-studio demonstrations—she emphasizes the “stories” Plants themselves: Dr. Dr. Kleier Share with you the joys of being able to identify and understand the workings of that tree just outside your window – and of any other plant you may encounter.

With almost 400,000 known species and thousands more identified every year, the variety of plant life is almost overwhelming—from the microscopic to The largest organism on Earth. In Plant Science: An Introduction to BotanyYou will discover the amazing adaptations that plants can make. to You can live in a wide range of ecosystems from the desert to the ocean floor. to You can see thousands of feet higher than sea level on every continent. You’ll see why there are so many. Three Different types of photosynthesis and how they separate plants from animals. Many plants also rely on the symbiosis between bacteria and fungi as part of their photosynthetic processes.

A New Way to See Plants. A New Way.

Recent research in botany has revealed astonishing insights about the diurnal sleep and waking cycles for trees. A DNA analysis has shown that fungi and humans are more closely related to More people than to plants. These and other discoveries show how taxonomic identification has changed since the advent of DNA sequencing.-Cutting edge scientific breakthroughs that allow us to better understand the world around our bodies, such:

• Scientists are never able to comprehend the complexity of science. to In the laboratory, lichen was grown. It was finally discovered that lichen is not a plant or an animal. “sandwich” There are three distinct organisms
• How plants are no different from beavers building dams. “ecosystem engineers” They are capable of protecting their territory
• Blue plants are rare
• 600 species of plants consume animals for nutrients. Others are poisoned.-injecting hairs
• What plants can you grow? to It can grow to enormous sizes, similar to grass. to 130 feet tall, with leaves over 80 feet in length. Trees that bear 92-Pound fruit
• The science behind genetically modified organisms, and the real issues that GMO technology presents

BotanyStranger than Fiction

Plant Science: An Introduction to Botany Lectures are the first step. We will discuss the common features of plants and how they differ from humans. Also, we will explain why there are not many universal rules that apply to all plants. Later lectures will show how natural selection has enabled plants to flourish. to You can adapt to You can find the most diverse environments around the world. These adaptations have allowed to Amazing plant adaptations almost seem like magic! to These have been derived directly from science fiction such as:

• Stone plants Transparent “windows” to Allow just the right amount to enter your skin
• There are leaves that can photosynthesise underground and those that produce antifreeze
• Trees that produce a desired scent are highly sought after-Suberin is a waterproofing substance that chemists are unable to create. to You can either duplicate the item in a laboratory or fully describe it.
• A plant with only 5 per cent of its cells still alive, but which creates its ecosystem and constantly modifies its habitat.
• The oldest known living tree, it was born near the end the Neolithic period and more than 5,000 years ago.
• A Siberian seed that was viable for 31800 years before it was germinated was still viable
• A tropical tree (Hura crepitans) That shoots its seeds at high speeds to It is also possible to travel 150 miles an hour to Be the highest speed recorded in the animal kingdom
• mushroom The fairy rings What the Hyphae do and how they work to For fungal growth, enrich the soil
• A 11,000-Year-Clone of old creosote from the Mohave Desert
• the heaviest, oldest, and largest organism on planet Earth—a 107-acre, 80,000-Year-old, 6,600-Ton aspen (Populus tremuloides) genet—36 times heavier than the blue whale, the largest modern animal.

Although the number of reproductive methods in the animal kingdom is very limited, there are many options for sexual and asexual reproduction. Many of the oldest reproductive methods, like spores are still in use today and support thousands of species. Even though there were other reproductive methods that developed later, each has its unique advantages and challenges. A flowering plant, for example, must be able to bear fruit. “figure out” How to move male gametes to The fertilized ovules of the female ovules will grow into seeds inside the fruit. How do individual plants reproduce? Learn about the different aspects of plant reproduction.

• The benefits of sexual vs. non-sexual reproduction
• The roles of water and wind in plant reproduction
• plants that are completely dependent on animals for their reproduction—in some cases only one species of animal
• The many “tricks” Use of plants to In order to lure animals into their reproduction process, you can use flowers that look and smell like female bugs to attract them. to Attract males to your place “mating”
• “deceit pollination” Why it works
• How plants address themselves and recognize their own self-Pollination
• The role hormones play during the reproduction of the squirting cucurbit (Ecballium elaterium)

A Passionate Adventure With Plants

Dr. Kleier Also, fascinating questions botanists are still answering to answer. We know that plants are able to sense and respond. to They can remember what they have experienced in their environment, but are they able to recall their memories? We know that plants communicate. to Others in their immediate vicinity by chemical signals. But is it possible that some plants have developed an ability? to Are you able to detect sound waves We know which plants respond to sound waves. to Touch, but can they still be conditioned? to “learn” When it is not necessary to respond? The most fundamental of all questions is: What exactly are species? Scientists now have access to to It is easy to use genetic techniques like DNA fingerprinting. to find different alleles for different genes. It is difficult to count how many different alleles it takes. to Is it possible to identify a new species of plant? It’s an ongoing and exciting debate in the ever-Botany is changing the world

Botanists examine and evaluate nature constantly, and Dr. Kleier She is passionate about the field and watching plants in their various habitats. This passion shines through in every lecture she gives. to Do the same. This course explains that botany is a science grounded in experiences with plants. A vibrant set of encounters gives life to the plant diagrams, and long scientific names, of traditional biology.

Learn to You will see the world differently when you learn the stories of plant life from a professor who turns science into an adventure.
