Nutrition of a plant

The process of nutrition in plants is called photosynthesis and it is also a cycle:

1) Roots absorb water and nutrients from the soil (water + nutrients= raw sap)

2) Raw sap travels to the leaves and mix with sunlight and carbon dioxide (raw sap + CO2 + sunlight = elaborated sap)

3) Elaborated sap travels through the plant

Plants release oxygen as a result of this process.
