Plants are the main source of food and nutrients for
humans and animals. Many plants are grown as food
products. We use the fruits, leaves, seeds or roots of
such plants as foods. Some other plants are decorative
plants and are grown for their colorful and beautiful
leaves and flowers. Can you think of other reasons that
plants may be grown? How about medical use, exotic
fragrance or insect repelling properties?
No mater why you grow plants,
you want them to grow as fast as possible. If you are in
business of growing plants, faster plant growth results a higher
income for you. In order to be able to speed up plant growth,
you need to know how different factors may affect plant growth.
Light is one of such factors that can be studied. In this
project you will study to find out "What is the effect of
light on plant growth?".
