Chloroplasts
Photosynthesis is a process in which sunlight energy is used to make glucose. The site of
photosynthesis is in the chloroplast – a organelle found in the leaves
of green plants. The main functions of chloroplasts are to produce
food (glucose) during photosynthesis, and to store food energy.
Chloroplasts contain the pigment, chlorophyll. Chlorophyll absorbs
most of the colors in the color spectrum, and reflects only green and
yellow wavelengths of light. This is why we see leaves as green or
yellow – because these colors are reflected into our eyes.

make sugar by using the energy from sunlight to transform CO
from the air with water
2
from the ground into glucose. This process, called photosynthesis, occurs in the chloroplast
of the plant cell. During this process, oxygen (O
) is created as a waste product and is

released into the air for us to breath. The formula for photosynthesis is:
CO2 + H2O + sunlight ---- C6H12O6 + O2
This formula says that carbon dioxide and water molecules are combined with the energy
from sunlight to produce sugar and oxygen. The reactants in photosynthesis (what is used)
are CO
, water and sun. The plant gets water from the ground through its roots. The plant
2
collects carbon dioxide from the air. Much of the carbon dioxide comes from living
organisms that exhale it, but some also comes from factory smokestacks and car fumes.
7. What is the formula for photosynthesis?
8. What three things are used to make glucose in photosynthesis?
9. Where does the water come from?
10. Where does the water enter the plant?
11. What are some sources of CO2?
12. What type of energy does the plant use to convert CO2 and H2O into sugar?
The products (what is made) are glucose and oxygen. The glucose produced is used by the
plant for energy and growth. We also use this glucose by eating plants. The oxygen produced
is released into the air for us to breath. Photosynthesis is essential for all life on earth,
because it provides food and oxygen.
