How Plants Thrive in Extreme Conditions
In How Plants Thrive in Extreme Conditions, narrator Sir David Attenborough describes plants that thrive in some of the harshest places on Earth. The dragon’s blood tree in Socotra uses its unique shape to catch the morning mist and water its roots, while the desert rose stores water in its thick trunk and grows right out of bare rock. Meanwhile, the red mangrove tree survives salty water by filtering out most of the salt through pores, showing how nature helps plants adapt to tough environments! This video is excerpted from BBC’s Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.
Lesson Express
Q: How do the adaptations of these plants (dragon’s blood tree, desert rose, and red mangrove) show the importance of nature’s ability to help plants survive in extreme conditions?
A: These plants show that nature provides special adaptations to help them survive in extreme conditions, like dry deserts, salty waters, or rocky terrain. Each plant has developed unique features — such as storing water, filtering salt, or catching mist — that help them thrive where other plants would struggle.
Q: What makes the red mangrove tree so special in how it deals with salty water, and why is this important for its survival?
A: The red mangrove tree has special roots that filter out 99% of the salt in the water, allowing it to survive in salty environments where most plants would die. This adaptation is crucial because it helps the mangrove thrive in coastal areas where few other plants can live.
Q: If these plants didn’t have their special adaptations, how do you think their survival would be affected in these harsh environments?
A: Without their special adaptations, these plants wouldn’t be able to survive in such tough conditions. The dragon’s blood tree wouldn’t get enough water, the desert rose would run out of water in the dry environment, and the red mangrove wouldn’t survive the salty water. Their unique features are what allow them to survive and grow in places where most other plants can’t.

In Antarctica and Our Climate, geologist Iain Stewart explains how technology allows us to see the full geography of Antarctica, including lakes that are under ice and huge glaciers that cover islands of rock. Antarctica is formed because we are in an ice age that has lasted more than three million years, with small changes that have a large impact as ice advances and retreats over and over again.
