What tree has straight roots?

The tree known for having straight roots is the mangrove tree, particularly species like the red mangrove. These trees typically exhibit prop roots that extend vertically from the trunk and anchor into the soil, providing stability in coastal environments. Their straight, exposed roots help them adapt to tidal fluctuations and stabilize the shoreline. Other trees, like the black locust, may also have relatively straight roots, but mangroves are most recognized for this characteristic.
