Winning vascular plants! – Crash Course in Biology #37

Hank introduces us to one of the most diverse and important families of the tree of life: vascular plants. These plants have been hugely successful and their secret also lies in their distinctive trait: conductive tissues that can transport food and water from one part of a plant to another. Although it seems simple, the ability to move nutrients and water from one part of the body to another was an evolutionary advance for vascular plants, allowing them to grow exponentially, store food for lean periods and to develop characteristics that allowed them to spread further. and faster. Plants dominated the Earth long before animals even appeared and today still hold world records for the largest, most massive and oldest organisms on the planet.
