What is a plant? Plants are living things that grow in almost every part of the world. Plants grow on mountaintops, in oceans, in deserts, and in snow- covered areas. Some plants tower over people and animals. Others are so tiny that they can hardly be seen! Plants can have long lives. The oldest trees are California's bristlecone pines. Some of these trees are between 4,000 and 5,000 years old! Most roots grow under the ground. They hold the plant in the soil. They also take in water and minerals that the plant needs to grow. The stem holds up the plant and carries food to all parts of the plant.

什么是植物?植物是一种生物，几乎生长在世界的每一个角落。 植物生长在山顶、海洋、沙漠和积雪覆盖的地区。 有些植物高过人和动物。 还有一些小得几乎看不见!植物可以有很长的寿命。 最古老的树木是加利福尼亚的狐尾松。 其中一些树的年龄在4000到5000岁之间!大多数根生长在地下。 他们把植物埋在土里。 它们还能吸收植物生长所需的水和矿物质。 茎支撑着植物，并将食物输送到植物的各个部分。

Flowers grow from buds along the stems of a plant. Seeds are made inside the flowers. Leaves make food for the plant. It's a fact! The tallest trees are California's redwoods. Some are several stories taller than the Statue of Liberty!

花是从植物的花蕾沿着茎长出来的。 种子是在花里面产生的。 叶子为植物提供食物。 这是事实!最高的树是加州的红杉。 有些比自由女神像还高几层!

How do plants grow? All living things need energy to grow. Animals get energy from the food they eat, such as plants and other animals. But plants make their own food from sunlight. Most plants also need water, air, and soil to grow. The drawings show the growth of a bean plant. Water lilies can live with most of their parts underwater. The plant's beautiful flowers grow on long stalks that rise from the mud bottom. 5 Beans grow from the flowers.

植物是如何生长的?所有生物的生长都需要能量。 动物从它们所吃的食物中获取能量，比如植物和其他动物。 但是植物自己从阳光中获取食物。 大多数植物也需要水、空气和土壤来生长。 这些图画显示了豆类植物的生长情况。 睡莲的大部分身体部位都能在水下生活。 这种植物美丽的花朵长在从泥底升起的长茎上。 豆子从花里长出来。

1 Plants begin life as a seed. A seedling grows from a seed. 2 The root grows down. The stem breaks through the soil. 3 The buds become the first leaves. 4 The stem grows upward. Leaves grow and flowers begin to bloom. It's a fact! Bamboo is a type of grass that grows very quickly. One bamboo grew 36 inches (91 centimeters) in a day. That's taller than a two-year-old!

植物从种子开始生长。 种子长成幼苗。 根向下长。茎破土而出。 蓓蕾变成了第一片叶子。 茎向上生长。叶子生长，花朵开始绽放。 这是事实!竹子是一种长得很快的草。 一棵竹子一天能长36英寸(91厘米)。 比两岁小孩还高!
