People call it the "shy plant" because its leaves close at once when you touch them. Why does it do this? There is a small part at the base of each leaf called a pulvinus. When touched, water in the pulvinus flows to other parts of the leaf. The leaf loses water and becomes soft, so it closes up. This is a way to protect itself from animals that want to eat it. The Giant Baobab Baobab trees grow in Africa and Australia. They have huge, thick trunks that can store a lot of water—up to 120,000 litres! This helps them live in hot and dry places. Baobabs can live for more than 1,000 years. Their fruit is sweet and can be eaten, and their bark can be used to make cloth and ropes. The Night-blooming Cereus The night-blooming cereus is a kind of cactus. It only blooms at night, usually between midnight and dawn. Its flowers are big and white, and they have a sweet smell. But the bloom only lasts for one night—by morning, the flower fades. That’s why it’s also called the "queen of the night". ( )1. Which part of a newspaper can we read this passage? A. SPORTS B. NATURE C. CULTURE D. BUSINESS ( )2. Why do the leaves of Mimosa pudica close when touched? A. Because it is afraid of people. B. Because water flows in its leaves. C. Because light makes it close. D.
