The essential nutrients of plants and soil

1. PLANT NUTRITION

2. RESPIRATION
● Plants breathe.
● They take oxygen
from the air and
release carbon
dioxide.
● This process takes
place in leaves.

3. Plant nutrition
● Plants are
autotrophs: they
make its own food.
● To make food, plants
need:
sunlight,
carbon dioxide,
water and
minerals.

4. Water and minerals
● In the soil, minerals
dissolve in water.
● Plants absorb this
water through their
roots.
● These nutrients, raw
sap, travel up the
stem to the leaves.

5. PHOTOSYNTHESIS
● Photosynthesis
enables plants to
make food from
sunlight, carbon
dioxide, water and
minerals.

6. PHOTOSYNTHESIS
● Photosynthesis
takes places in the
leaves.
● Raw sap mixes
with carbon dioxide
and becomes
elaborated sap.

7. PHOTOSYNTHESIS
● This elaborated sap
is the plant´s food.
● Sunlight is essential
for photosynthesis.
● During
photosynthesis,
plants release
oxygen.
