Holds the plant firmly in the soil and absorbs water and minerals from it. Some roots also store food, as in carrot and radish.

Holds up the branches, leaves, flowers and fruits. It carries water and minerals up from the roots to the leaves, and food from the leaves to other parts.

Makes food for the plant by photosynthesis, using sunlight, carbon dioxide and water; the green pigment chlorophyll traps the light. Water vapour leaves through tiny pores called stomata (transpiration).

The reproductive part of the plant. After fertilisation it gives rise to the fruit, which contains the seeds.

An unopened flower. When it opens, it becomes a flower.

The small green, leaf-like parts at the base of the flower. They protect the flower while it is still a bud.

Usually brightly coloured. Petals attract insects, which carry pollen from flower to flower.

The top of the stamen. It makes the pollen grains, which carry the male cells.

The thin stalk of the stamen that holds the anther up.

The sticky top of the pistil. Pollen grains land and stick here during pollination.

The tube-like part of the pistil that joins the stigma to the ovary.

The swollen base of the pistil. It contains the ovules; after fertilisation the ovary becomes the fruit and the ovules become seeds.

The Sun's heat turns water from seas, rivers and lakes into water vapour, which rises into the air.

Plants give out water vapour through the tiny pores (stomata) in their leaves, adding more vapour to the air.

Higher up, the air is cooler. The water vapour cools and changes into tiny droplets of water, which together form clouds.

When the droplets join and become heavy, the water falls back to the earth as rain, snow or hail.

Rainwater flows over the land into streams and rivers, and finally back into the sea.

Some rainwater soaks into the soil and collects below the ground as groundwater, which we draw from wells and hand pumps.
