Explain how the image below shows a biochemical pathway.

This is the pigment that is directly involved in photosynthesis.

Explain how autotrophs and heterotrophs differ in terms of how they obtain nutrients.

Use the following terms to explain the endosymbiotic theory: small photosynthetic prokaryote, large heterotrophic prokaryote, endocytosis, double membrane.

Name the pigments that turn plants yellow, orange, and brown.

Explain why stomata are important in terms of gas exchange.

Which organelle is pictured below? Is this in plant or animal cells?

Point out the stroma, granum, and thylakoid.

Point out where the light reactions of photosynthesis take place.

Point out where glucose is made.

Plant appear green because chlorophyll __________ all colors of light besides green and _____________ green light. Fill in the blanks with these words: reflect/transmit, absorb.

The thylakoid membrane is a ____________ bilayer.

Once the sun shines on the plant, electrons are kicked out of PSII, travel to the PEA, and then travel down the ETC. Do they gain or lose energy after they travel down the ETC?

Where does the H + ion pump get the energy to pump H + ions across the thylakoid membrane?

Does the H + ion pump use active or passive transport to move H + ions? Please explain.

What is the purpose of creating an H + gradient across the thylakoid membrane?

Where do the PSII electrons get recharged?

Explain how the NADPH “batteries” are made.

Explain how the ATP “batteries” are made.

Where is the enzyme that splits water located in the chloroplast?

When is O 2 “waste” made in the light dependent reactions of photosynthesis?

Why is O 2 “waste” important in photosynthesis?

How are the PSII electron replaced in photosynthesis?

Final Jeopardy

Use your thylakoid membrane poster and game pieces to explain to your group members how the light dependent reactions of photosynthesis work.
