Parts of a plant

Roots, stem, leaves and flower — and the job each part does.

About 15 minutes

Step 1 · Wonder why it matters

Hook

A sunflower taller than you

Some sunflowers grow taller than a grown-up — from one tiny seed! How does a plant drink, stand up and make new seeds?

Every part of a plant has its own job. Let's meet them.

Step 2 · See it

Picture

See the parts

Start at the bottom, under the soil, and work your way up.

PartWhere it isIts job
RootsUnder the soilHold the plant in the ground and take in water
StemAbove the soilHolds the plant up and carries water to the leaves
LeavesOn the stemUse sunlight to make food for the plant
FlowerAt the topMakes seeds so new plants can grow

Step 3 · Understand how it works

Logic

Working together

Water goes in through the roots, travels up the stem and reaches the leaves.

The leaves use sunlight, air and that water to make food. The flower makes seeds. When the seeds fall to the ground, new plants can grow.

Roots
The part under the soil that drinks water.
Stem
The stalk that holds the plant up.
Seed
A tiny package that can grow into a new plant.

Step 4 · Have a go

Do

Have a go

Do this with a grown-up.

  1. 1Find a plant in the garden, park or on a windowsill.
  2. 2Point to the stem, the leaves and the flower if it has one.
  3. 3Draw the plant and label each part.
  4. 4Put a white flower or a stick of celery in coloured water and look at it the next day. What has happened?

Step 5 · Remember it
