Examples of terrestrial plants include anything that grows on the ground, including potato plants, sunflowers, poison ivy, daisies, evergreen trees and cacti. Terrestrial plants are contrasted with aqueous plants, which grow in the water. Some plants, like certain reeds, blur the line between aqueous plants and terrestrial plants, since they grow partially in water.
Terrestrial plants can grow in one of seven terrestrial ecosystems. These ecosystems are: tundra, taiga, grasslands, tropical rain forests, deserts and deciduous forests. Varying terrestrial plants can grow in each of these different ecosystems, often showing extreme diversity based on temperature and precipitation levels, as well as other environmental factors.
