Rainforest Plants Quiz – The Richest Plant Life on Earth

Tropical rainforests are warm, wet forests near the equator, found in the Amazon, Central Africa, Southeast Asia and Australia. Although they cover only about 6% of Earth's land, they hold around half of all plant and animal species.

Rainforest plants compete fiercely for light. Emergent trees tower above the canopy, vines climb toward the sun and epiphytes like orchids and bromeliads grow on branches. On the dim forest floor, plants have large leaves to catch scattered light, and many trees rely on buttress roots.

Rainforest plants give us foods such as chocolate, coffee, vanilla and bananas, and medicines like those from the Madagascar periwinkle. Deforestation for farming, logging and mining threatens these forests, so protecting them is vital for climate and biodiversity.
