Autotrophs such as green plants contain green pigments called chlorophyll (in the chloroplasts). A pigment absorbs certain wavelengths of light and reflects other. A chlorophyll pigment absorbs blue and red light and reflects green light. Therefore the leaves appear to be green.
When light is absorbed by green plants, the light energy is used to synthesize organic compounds such as sugars from inorganic compounds, water (absorbed by the roots of the plants from the soil) and carbon dioxide (obtained from the atmosphere and enters the plants through the stomata of the leaves by diffusion). This process is known as photosynthesis and can be summarized by the following equation.
The GLUCOSE produced during photosynthesis can be converted into other forms of carbohydrates such as starch (for storage) and other complex sugars (sucrose). Notice in the equation, oxygen is also produced as a by product. This oxygen is useful and can be used by other organisms and the plants themselves for respiration.

REQUIREMENTS (CONDITIONS) FOR PHOTOSYNTHESIS:
- Carbon dioxide
- Water
- Chlorophyll
- Light energy
These requirements must be present for plants to photosynthesize. Without one, plants will not be able to photosynthesize.
WHERE IN THE LEAF DOES PHOTOSYNTHESIS TAKING PLACE?
CHLOROPLASTS...... CHLOROPLASTS..... CHLOROPLASTS.... *Hitting the white screen with my purple broom stick*
NOTE: SINCE THE STUDENTS' PRESENTATIONS, I LONGED FOR MY PURPLE BROOM STICK!!!
