If you look around right now, chances are you'll see a plant. It could be a succulent in a pot on your desk, grasses or shrubs just outside your door, or trees in a park across the way. Proximity to plants tends 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.
In the 24 lectures of Plant Science: An Introduction to Botany, Dr. Catherine Kleier invites us into the uniquely satisfying world of plants, and the joy of celebrating and learning from the secrets of living nature. As 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" of plants themselves: Without neglecting genetics or cell microbiology, or larger ecosystems and habitats, her primary emphasis is always on how plants we see all around us live and adapt. Dr. Kleier shares with you the pleasures 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 Botany, you will explore the astonishing adaptations that allow plants to live in an enormous variety of ecosystems, from deserts and the ocean floor to thousands of feet above sea level and on every continent. You will understand why there are no fewer than three kinds of photosynthesis, how the process separates plants from animals, and why many plants rely on symbiosis with bacteria and fungi in conjunction with photosynthetic processes.
See Plants in a New Way. And Another New Way.
Recent scientific research from botany has offered astonishing revelations about the diurnal sleeping and waking cycles of trees. And DNA analysis proves fungi are actually more closely related to humans than to plants. These and many other discoveries illuminate the ways taxonomic identification of plants has changed with the advent of DNA sequencing and other cutting-edge scientific breakthroughs, allowing for a greater understanding of the world around us, such as:
How scientists, never able to grow lichen in the lab, finally determined that lichen is neither plant nor animal, but a "sandwich" of three distinct organisms
How plants, no less than beavers building a dam, are "ecosystem engineers" and capable of protecting their territories
Why you rarely see blue plants
Why 600 species of plants eat animals for nutrients, while others are outfitted with poison-injecting hairs
How some plants can grow to enormous size, like grass that can reach to 130 feet tall and leaves measuring more than 80 feet long, or trees that bear 92-pound fruit
The science behind genetically modified organisms and the real issues presented by GMO technology
