2. Photosynthesis
In the process of photosynthesis, plants convert light energy from the
sun into chemical energy in the form of glucose or sugar.
Water + Carbon Dioxide + Sunlight Glucose + Oxygen
3. Photosynthesis
Food for Plant
They use the sunlight and the green in their leaves to make sugars from
carbon dioxide (which they breathe in through their leaves during the day)
and water. This sugar is then used to give the plant energy so that it can
grow. This process is called photosynthesis and is the most important
process on the planet, as many other plants and animals depend on plants
to survive. Most of the energy is used to make new plant material, although
some of it is stored by the plant for use during the months when there is less
sunlight.
A Breath of Fresh Air
During the night, plants breathe in oxygen. This is called
respiration. The plant also needs minerals to grow, which the plant
takes from the soil where they are dissolved in water. The plant
releases any water that it doesn't need into the air through its
leaves. This is called transpiration.
Plants are the only living organisms that can make their own food.
This is one of the main ways of deciding if something is a plant.
