5 How flowers grow

How flowers grow

Lots of flowers. There are thousands of different kinds of flowers growing all over the world. These amazing flowers are passion flowers.

Seeds to seedlings. A seed has a hard shell with a young plant inside. Seeds grow in the soil when the sun and rain has made them warm and wet. These are sunflower seeds. Each sunflower seed can grow into a big sunflower.

In the soil, the shell of a seed splits. A small root sprouts out of it. Then a shoot grows out of the seed. When a shoot breaks through the soil, it is called a seedling. The largest seed in the world is the coco de mer. It is bigger than a football.

Plant parts. Most plants are made up of flowers, leaves, roots and stems. This is a wood sorrel plant. The stems keep the plant upright. Leaves and flowers grow on the stems. Plants make food in their green leaves.

Some plants have leaves that are sharp and spiky. They grow well as animals prefer to eat smooth leaves. Lots of things you eat are plant parts. Broccoli is a bunch of flowers and carrots are a kind of root. Underground, the roots soak up water from the soil. They hold the plant in place too.
