Photosynthesis Review

General Photosynthesis

100

the equation for photosynthesis in words...

Carbon dioxide + water + light > oxygen and glucose 

200

the organelle where photosynthesis occurs 

chloroplasts 

300

the equation for photosynthesis in symbols (with proper balancing)

6CO₂ + 6H₂O + Light > C₆H₁₂O₆ + 6O₂

400

 plant structure where chloroplasts are typically found 

leaves 

500

plants are green because...

chloroplasts contain chlorophyll A and B, which are green pigments 

Light Reactions

100

the location of the light reactions 

thylakoids 

200

the requirements needed for the light reactions

Light and water 

300

the products of the light reactions 

NADPH, ATP, and O₂

400

a stack of thylakoids is known as 

a grana 

500

factors that would affect the rate of the light reactions 

Light intensity, wavelength, amount of water

Calvin Cycle

100

the location of the calvin cycle 

the stroma 

200

the requirements needed for the calvin cycle 

CO_2, ATP, and NADPH 

300

the products of the calvin cycle 

glucose (mainly),  G3P can be made into other macromolecules 

400

calvin cycle can occur in the _____ and the ______

light; dark

500

factors that would affect the rate of the calvin cycle

CO₂ amount, ATP and NADPH abundance 

Wavelengths

100

the wavelengths of light humans can perceive are called 

the visible light spectrum 

200

The shorter the wavelength, the _______ it is in energy 

higher 

300

Green plants absorb these wavelengths the best 

Violet, blue, and red 

400

***DAILY DOUBLE***

Green light is not good for plant growth because.....

green light will be reflected by chlorophyll and will not be absorbed by the leaves of a plant, leaving the light reactions with no light to capture, leading to the decrease in ATP and NADPH production, then leading to the decrease in glucose production

500

Violet, red, and blue wavelengths are best for photosynthesis because...

Due to its chemical structure, chlorophyll can readily absorb these wavelengths and will reflect others, allowing photosynthesis to occur as intended

Misc.

100

Photosynthesis and cellular respiration are related in that they are 

inverses of each other 

200

In words, the goal of photosynthesis is to convert _____   energy into _____

Solar energy/light energy into chemical energy

300

List at least 3 pigments we discussed in class and lab

Chlorophyll A, Chlorophyll B, Carotenoids, Anthocyanins 

400

List the five main factors that affect photosynthesis 

Light quality (wavelength), light intensity, light period, CO₂ availability, H₂O availability

500

if grana were no longer being synthesized in plant cells, what would no longer be made>

ATP and NADPH
