How Plants Make Their Own Food
Discovering the Amazing Process of Photosynthesis Year 5 Science
Think About This...
What do you think plants eat for breakfast? How do you think plants get their energy? Have you ever wondered why plants are green?
Plants Are Amazing Food Makers!
Unlike animals, plants don't need to find food They make their own food using simple ingredients This amazing process is called photosynthesis Photo = light, Synthesis = putting together
The Three Magic Ingredients
Sunlight - provides the energy Water - absorbed through roots Carbon dioxide - taken in from the air These three ingredients are mixed together to make food!
The Photosynthesis Process
Meet the Chloroplasts!
Tiny green factories inside plant cells Contain a green substance called chlorophyll Chlorophyll captures sunlight energy This is why most plants look green!
What Goes In vs. What Comes Out
{"left":"Sunlight (energy)\nWater (H₂O)\nCarbon dioxide (CO₂)","right":"Glucose (plant food)\nOxygen (O₂)\nFresh air for us to breathe!"}
Let's Act It Out!
Stand up and pretend to be a plant! Stretch your arms up high like branches reaching for sunlight Wiggle your fingers like roots drinking water Take deep breaths to collect carbon dioxide Now make your own food and release oxygen!
Why Is Photosynthesis So Important?
Plants make their own food to grow big and strong Oxygen is released for animals and humans to breathe Plants form the base of all food chains Without photosynthesis, there would be no life on Earth!
Remember This!
Plants + Sunlight + Water + Carbon Dioxide = Food + Oxygen Plants are the ultimate recyclers - they turn simple ingredients into the food and air that keep our planet alive!
