Plants don't eat — they make their own food in their leaves using sunlight. This lesson explains photosynthesis and the jobs of roots, leaves and flowers, clearing up the 'plants eat soil' misconception.
Using energy from sunlight, leaves combine water and carbon dioxide into sugar (food), releasing oxygen. This is photosynthesis.
Roots take in water and minerals and anchor the plant. Minerals help the plant grow but aren’t its food.
Pollination (often by insects) lets flowers form seeds, which grow into new plants.
What does a plant need to grow well, and why does one in a dark cupboard die?
They make their own! Plants take WATER and minerals from soil, but their food is made in the leaves by photosynthesis using sunlight.
They use carbon dioxide! For photosynthesis, plants take in carbon dioxide and release oxygen — the reverse of our breathing.
Leaves make food! Roots absorb water and anchor the plant; the food factory is the leaf.
In their leaves, by photosynthesis: sunlight provides energy to combine water and carbon dioxide into sugar, releasing oxygen. Plants make their own food rather than eating it.
No — they absorb water and minerals from soil through their roots, but their food is made in the leaves using sunlight.
Roots absorb water and anchor the plant; leaves make food; the stem carries water and holds the plant up; flowers make seeds for reproduction.
