__________.

During photosynthesis __________ energy is

converted to __________ energy.

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 O2 “waste” made in the light dependent reactions of

photosynthesis?

Why is O2 “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.
