Plant Nutrition
Plants need all the same food groups, vitamins, and minerals as us, but they don't have mouths to eat with.

How do plants get food?
- Plants need to get their nutrients by other means.
- They get their minerals from the soil, when they are absorbed through their roots.
- They get their water in the same way, absorbing it from the soil using their roots.
- They get the other nutrients (e.g. carbohydrates) from photosynthesis.
Photosynthesis
- Photosynthesis produces glucose (a sugar) from:
- Carbon dioxide (absorbed from the air through their leaves).
- Water (absorbed from the soil through their roots).
- The energy in sunlight (absorbed by the chloroplasts in their leaf cells).

Which of these is NOT needed for photosynthesis?
Where do plants get their nutrients?
A gardener keeps a healthy plant in a dark cupboard with plenty of water and soil nutrients. What happens to the plant's production of glucose?
How do plants obtain the nutrients they need?
A plant's soil completely dries out, but the plant still gets plenty of light and carbon dioxide. What happens to its production of glucose?
