ProjectPHOTOSYNTHESIS
FOOD FROM THE SUNanimals eat plants to get energy, other
animals eat these animals, plants produce their own food from the sun
WHAT IS PHOTOSYNTHESIS?plants absorb carbon dioxide through their
leaves, water through their roots. Chlorophyll in leaves absorbs energy from the sun
THE LIGHT AND DARK REACTIONSfirst stage is called light reaction where light
is converted to chemical energy Second stage is dark reaction where the plant converts carbon dioxide and water to carbohydrates
A LIFE-GIVING PROCESSthe plant produces food and also provides oxygen
for life. Plants produce their own food from the sun through a process called photosynthesis Photosynthesis uses carbon dioxide, water, chlorophyll and sunlight to produce carbohydrates which the plant uses as food There are two stages in photosynthesis The first stage is called the light reaction and involves converting light energy to chemical energy and the second stage is called the dark reaction and consists in converting the carbon dioxide and water to Carbohydrates The equation for the process is
green plants Photosynthesis not only produces food for the plant but it also produces oxygen which is essential for all life on this planet.
