green plants make sugars. A plant's leaves contain a green
substance called chlorophyll (it is this that gives plants their
characteristic color). The chlorophyll uses light energy from the
sun to combine carbon dioxide and water to produce sugar. The
water comes from the soil via the plant's roots while the carbon
dioxide comes in through tiny pores in the plant's leaves called
stomata. The by-product of this process is oxygen.
The amount of sugar in plants
depends on many different factors. The most important factor is
plant type. That is why certain plants such as sugar cane and
sugar beet are planted just for producing sugar. In this project
we will study the amount of sugar in different plants and
different conditions. There are many different types of plants and
many different conditions (light, temperature, amount of water,
..) that you may select for your study.
