Photosynthesis
Green plants and algae use light energy to make
their own food. They obtain the raw materials
needed from both the air and the soil. The
conditions in which plants are grown will affect the
rate of photosynthesis and the rate of growth.…read more

During photosynthesis...
Light energy is absorbed by chlorophyll
This energy is used to convert carbon dioxide
and water into glucose
Oxygen is released as a by-product…read more

Limiting factors
Light
Temperature
Carbon dioxide
Enhancing these factors in greenhouses will
produce better yields…read more

Slide 5

Using the glucose
Glucose produced in photosynthesis may be converted
into insoluble starch for storage or growth
Plant cells use some of the glucose straight away for
processes such as respiration
It can also be used to produce
· Fat or oil for storage
· Cellulose
· Proteins ( nitrate ions are also used to produce these)…read more
