Food made from light
Photosynthesis is the amazing process plants use to make their own food, and this puzzle gathers it. You'll be finding the ingredients — SUNLIGHT, WATER and carbon DIOXIDE — and the green PIGMENT in the LEAF that captures the light to make GLUCOSE and OXYGEN.
Because every new puzzle reshuffles the leaf, no two photosynthesis word searches are the same. One round a backwards STOMATA hides in a corner; the next a diagonal GLUCOSE appears across the middle.
Inside the plant
A plant is a clever food factory, and the words are here. WATER is drawn up by the ROOTS, through the STEM and the XYLEM and PHLOEM VEINS, to the LEAF where the CELLS ABSORB sunlight to PRODUCE SUGAR. Tiny holes called STOMATA let gases in and out, the plant stores energy as STARCH, and the whole PROCESS gives off the OXYGEN we breathe — keeping the PLANT GREEN and growing.
It's a great fit for a science topic on plants. Tracking down P-H-O-T-O-S-Y-N-T-H-E-S-I-S turns spelling practice into a biology lesson.
How to play
Drag across a word, or click its first and last letter — both work. Each word you spot locks in with its own colour and ticks off the list, so you always know what's left to find.

Frequently asked questions
What's in the photosynthesis word search?
How plants make food — sunlight, water and carbon dioxide turning into glucose and oxygen, plus the leaf, roots, stem and stomata. Each puzzle uses a fresh mix.
Is the photosynthesis word search free to print?
Yes. Play free online or download a printable PDF pack with optional answer keys — no sign-up required.
