Time lapse radish seeds sprouting

Watch more with these video collections:

A time lapse spanning 9 days shows the growth of radish seeds sprouting while their roots grow deeper into the dirt.

Many plants, such as trees and flowers, have vascular systems. These vascular plants have a system of tubes they use to transport nutrients and water to different parts of the plant. Vascular plants all have similar parts, such as stems, leaves and roots.

The roots, for example, have several important functions. They pull water and minerals from the environment to nourish the plant. This is why they grow down, because the water and minerals needed for growth are below the ground in the soil.

They also provide support and help anchor a plant to the ground. Without a strong root system, trees would not be able to stand tall and withstand high winds.

Roots can also store food and nutrients. A well-developed root system can also prevent soil erosion. Some roots are even edible. For example, the carrots we eat are the roots of the carrot plant!
