Photosynthesis foldable activity Don’t fold anything yet!

The Photosynthesis Equation Write your name and period at the bottom on the lines provided. Next to this, we are going to write the photosynthesis equation. To start the equation, think about what the plant takes in from the environment... 6CO2 + 6H2O light

Now, what are the products? Think about what heterotrophs must take in to survive… high-energy Glucose

Now fold the top of your paper down so that the equation still shows, but you can see Photo-synthesis on the top. What does PHOTO mean? LIGHT

WHOooo? WHO does photosynthesis? In the pentagon: what do we call organisms that make their own food? 3 Arrows from AUTOTROPHS: We all know plants undergo photosynthesis, but what else? some bacteria algae

Sequence of events: Light absorption Light Dependent Reactions Electron Transport Chain Chemiosmosis Calvin Cycle

Inside a Chloroplast Thylakoid Grana Chlorophyll/pigments Photosystems Stroma

Light-Dependent Reactions Where do they take place? Thylakoid membranes of chloroplasts What goes in (USES)? H20 ADP NADP+ What comes out (PRODUCES)? O2 ATP NADPH

The Calvin Cycle (Light-Independent Reactions) Where do they take place? Stroma of chloroplasts What goes in (USES)? ATP NADPH CO2 What comes out (PRODUCES)? Glucose ADP NADP+

Electron Carrier What does that mean? In photosynthesis, the electron carrier is: NADP+ accepts electrons with the H+ and becomes NADPH Happens in e- transport chain (chemiosmosis)

Factors affecting photosynthesis 1: Temperature The reactions of photosynthesis are made possible by enzymes that function best between 0°C and 35°C.

Factors affecting photosynthesis 2: Light High light intensity increases the rate of photosynthesis. After the light intensity reaches a certain level, however, the plant reaches its maximum rate of photosynthesis

Factors affecting photosynthesis 3. Water Because water is one of the raw materials in photosynthesis, a shortage of water can slow or even stop photosynthesis. What special adaptations do plants that live in dry climates have?

close it and flip it over On the back side of PHOTOsynthesis, draw the ATP molecule. adenosine triphosphate (ATP). ATP consists of adenine, a 5-carbon sugar called ribose, and three phosphate groups. How is the energy released? What is ADP?
