The Parts of a Plant Most plants have the same parts. They have roots, stems, and leaves. Each part helps the plant get what it needs to live. Roots usually grow down into the soil. Roots hold most plants in place. They help a plant stand tall. Roots also store water and food for the plant. Roots take in water and minerals from the soil. Plants need minerals to grow and be healthy.

植物的组成大部分植物都有相同的组成部分。 它们有根、茎和叶。 每个部分都帮助植物获得生存所需的物质。 根通常深入土壤。 根能固定大多数植物。 它们帮助植物挺立。 根也为植物储存水和食物。 根从土壤中吸收水分和矿物质。 植物需要矿物质来生长和健康。

The stem holds up the leaves so they can get sunlight. The stem carries water and minerals from the roots to all parts of the plant. Stems can also store water and food. Do You Know? Tree trunks are stems. The vines of strawberry and pumpkin plants are stems, too.

茎撑起叶子，这样它们就能得到阳光。 茎将水和矿物质从根输送到植物的各个部位。 茎也可以储存水和食物。 你知道吗?树干是树干。 草莓和南瓜的藤蔓也是茎。

Leaves grow above the ground where there is light. They need light to make food for the plant. Leaves are usually flat. The flat shape helps them catch sunlight. Try This Look carefully at a leaf. Are the edges smooth, wavy, or shaped like a saw? Is the tip pointy or round? Does it feel smooth rough, or bumpy? Does it feel sticky, hairy, or waxy?

有光的地方，叶子就长在地上。 它们需要光线为植物提供养分。 叶子通常是平的。扁平的形状有助于它们捕捉阳光。 仔细看一片叶子。 边缘是光滑的，波浪状的，还是形状像锯子? 尖端是尖的还是圆的? 它摸起来是光滑、粗糙还是颠簸? 是黏黏的，毛茸茸的，还是像蜡一样?
