PhotosynthesisIntroduction
Early Experimentation with Plants
1. How does a plant grow in mass?2. Do plants take substances out of the air
and put substances back in?
Read and answer question #1 in the packet.
PhotosynthesisEquation for Photosynthesis
6CO2 + 6H20 C6H12O6 + 6O2
This equation MUST be memorized!
AND
You MUST know what it means!

A Little Bit About ATPATP
• ATP is like the battery for the cell.• It is short for Adenosine Triphosphate.• It has an Adenine with ______Phosphates.• APPP
Power In the CellAdenosine TRIphosphate has 3 phosphates and is fully charged (like a battery).
It’s nickname is ATP.
Adenosine DIphosphate has __ phosphates and is no longer fully charged.
It’s nickname is ADP.
Adenosine MONOphosphate has __ phosphates and almost completely empty.
It’s nickname is ________.
What happens to ATP when it is used?
• ATP goes to ADP when it is used.
• ADP goes to AMP when it is used.

Plants need carbon dioxide which is in the atmosphere.
This is a chloroplast.

Carbon Dioxide enters the chloroplast and leaves as a six carbon sugar… C6H12O6
This is called Glucose.

1. Why is it good that the chloroplast removes carbon dioxide from the air?
2. Why do we need chloroplasts to create these sugars (how do we use these sugars)?

Journal and Next Assignment
• In your journal classify yourself as one of these:– Qualitative (artistic/creative/enjoys
visuals/scattered)– Quantitative (number based/ analytical/
factual/organized)• Then write: Journal completed on Packet
(I will count your photosynthesis question as your journal today).
Creative Assignment
• Use the packet to create a 11x17 poster that shows the process of photosynthesis visually AND verbally.
• The equation for photosynthesis must be included in 7 different places and the project must be complete and accurate.
• In addition to being worth a grade, the most original project will be awarded a fish.
Journals can get put away
• Tomorrow we’ll catch up on journal entries.
• Quiz on Photosynthesis tomorrow. Memorize the equation and the diagram.
