The Water Cycle Explained

1 2 3 4 5 6

6 labelled parts: Evaporation → Transpiration → Condensation → Precipitation → Runoff and collection → Infiltration and percolation. Watch it build, or tap a number.

Step 1 of 6: Evaporation

The Sun heats oceans, lakes and rivers, turning liquid water into invisible water vapour. Oceans supply most of it.

Step 2 of 6: Transpiration

Plants take up water through their roots and release vapour through tiny leaf pores called stomata.

Step 3 of 6: Condensation

Rising vapour cools and condenses into tiny droplets around specks of dust or salt, forming clouds.

Step 4 of 6: Precipitation

Droplets join and grow until they are too heavy to float, then fall as rain, snow or hail.

Step 5 of 6: Runoff and collection

Water flows over the land into streams, rivers and lakes, and finally back to the sea.

Step 6 of 6: Infiltration and percolation

Some water soaks into the soil and trickles down to become groundwater that feeds wells and springs.

Inside a Leaf: Labelled Leaf Cross-Section

A labelled cross-section of a leaf, from the waxy cuticle to the stomata. See how each layer, from palisade cells packed with chloroplasts to air spaces, veins and guard cells, helps the leaf photosynthesise.

Press play to watch it build, use the arrows to go at your own pace, or choose any number on the diagram.

Step by step

1 2 3 4 5 6 7 8 9

9 labelled parts: Waxy cuticle → Upper epidermis → Palisade mesophyll → Spongy mesophyll → Air spaces → Xylem → Phloem → Lower epidermis → Stoma and guard cells. Press play, or choose a number to explore.

Step 1 of 9: Waxy cuticle

A thin, waterproof and see-through layer of wax. It cuts water loss but lets light pass. It is usually thickest on the upper surface.

Step 2 of 9: Upper epidermis

One layer of clear cells with no chloroplasts, so light shines straight through to the cells below. It protects the inside of the leaf.

Step 3 of 9: Palisade mesophyll

Tall, tightly packed cells just under the surface, crammed with chloroplasts. Most photosynthesis happens here, where the light is brightest.

Step 4 of 9: Spongy mesophyll

Rounder, loosely packed cells with fewer chloroplasts. The gaps between them let gases spread through the leaf.

Step 5 of 9: Air spaces

Carbon dioxide diffuses through these gaps to every mesophyll cell, while oxygen and water vapour diffuse out towards the stomata.

Step 6 of 9: Xylem

Hollow tubes strengthened with lignin that bring water and mineral ions from the roots. In a leaf vein, the xylem lies on the upper side.

Step 7 of 9: Phloem

Living cells that carry dissolved sugars from the leaf to the rest of the plant (translocation). In a vein, the phloem lies below the xylem.

Step 8 of 9: Lower epidermis

The bottom layer of clear cells, covered by a thinner cuticle. In most plants it holds far more stomata than the upper surface.

Step 9 of 9: Stoma and guard cells

A tiny pore between two guard cells. They open it to let carbon dioxide in and oxygen out, and close it to save water.
