• A process in which plants convert light energy
from the sun into chemical energy in the form
of organic compounds (Carbohydrates).
•Photosynthesis
• Organelle where the process of
photosynthesis occurs.
•Chloroplast
• Gives plants its green color by reflects green
light.
•Chlorophyll
• Organisms that use energy from sunlight to
make organic compounds through the process
of photosynthesis.
•Autotrophs
What part of the photosynthesis
process does this occur?
• light + 6 C O₂ +
•Reactant
6 H₂0
What part of the photosynthesis
process does this occur?
• C₆H₁₂0₆ + 6 0₂
•Product
• Glucose and oxygen --> water and carbon
dioxide
• Process performed by:
• Plants and animals
• Animals and organisms that consume other
organisms to get energy.
•Heterotrophs
• Where does Energy for life comes that is used
in photosynthesis?
•Sun
• Where does carbon atoms come from in the
photosynthesis process?
•Carbon dioxide
• Where does Oxygen atoms come from in the
photosynthesis process?
•Water H2O
What is energy used for?
• Growth and reproduction
• Movement
• Transport material across the cell membrane
• A product of photosynthesis that is used as an
energy source by all living organisms.
•Glucose
Energy Flow
• Light energy -->
• chemical energy -->
• usable energy
Energy Flow
• Sun -->
• Chlorophyll-->
• Glucose
Two stages of photosynthesis
• Light reaction
• Calvin Cycle
• The reaction that produce organic
compounds(carbohydrates).
•Calvin Cycle
• Energy used n the Calvin Cycle comes from
•ATP and NADPH
