How do plants make food?
Plants need water to make their own food. This is called photosynthesis. It happens in plant leaves. Plants also need carbon dioxide from air and sunlight to make their food.

Water's journey through the plant

Plants absorb water from the soil through their roots. Plant roots have tiny hairs on them so they can absorb as much water as possible.

The water enters through the roots and travels up the stem in tubes. These are easy to see in plants like celery.

The water goes from the stem to the leaves. The stem holds out the leaves so the Sun can shine on them to make food. They also hold flowers out to attract insects.
