Chapter 10 Questions Flashcards
What are the reactants and products of photosynthesis?
6CO2 + 6H2O + Light energy —> C6H12O6 + 6O2
How does photosynthesis relate to cellular respiration? (see figure 9.2)
the net reaction for photosynthesis is essentially the reverse of the net reaction for cellular respiration
What cellular location does photosynthesis take place?
Leaves - chloroplasts
Which types of organisms undergo photosynthesis?
plants, algae, and some bacteria
Does photosynthesis rely on redox reactions? If so, what is being oxidized and what is being reduced in the overall equation for photosynthesis?
Yes
oxidation of H2O and the reduction of CO2
How does CO2 enter and O2 exit from plant leaves?
through microscopic pores called stomata
What are the two major locations inside chloroplasts?
Stroma and thylakoids
What are the two reactions that carry out photosynthesis?
Light Reactions and Calvin cycle
What is the wavelength range for visible light?
380-750 nm wavelengths
If chlorophyll appears green, which colors of the visible spectrum are being absorbed and which are being transmitted?
chlorophyll reflects and transmits green light
Which colors of the visible spectrum are mainly being used to fuel photosynthesis?
violet-blue and red light
Which colors of the visible spectrum are not being used for photosynthesis?
Green
What is the primary photosynthetic pigment in green plants?
chlorophyll a
What are the accessory pigments we talked about during class?
chlorophyll b and carotenoids
What is the purpose of having accessory pigments?
to broaden the amount of light that can be harnessed to fuel photosynthesis
