DVD Description
Our Plant DVD starts by looking at the watery origins of modern land plants before looking at the adaptations that have evolved in plants and enabled them to spread to nearly every corner of the Earth. These adaptations include: roots, which anchor plants and absorb water and nutrients from the soil; vessels, that conduct water and nutrients throughout a plant; lignin, which stiffens and supports plants enabling them to grow taller; pollen, which frees plants from a dependence on water for reproduction; and fruits, which entice animals to unwittingly spread a plants seeds far and wide.
