Age 8: open this week

In the picture

A leaf: it makes the sugary sap
The branching tubes in the stem: the sap travels along them
The tight green bud: sap arrives and it starts to grow
The small red fruit: sap helps it swell and ripen

Examples

A maple tree’s sweet sap is boiled down to make syrup.
A strawberry plant’s leaves feed the small green berries until they turn red.

Key takeaways

Leaves make sugary sap from sunlight, water and air.
Sap moves through tubes in the stem to feed new leaves, flowers and fruit.
