1. Explain
the role of photosynthesis in providing energy and matter for life.
2. Describe
the anatomy of a chloroplast. Be able to
diagram where the thylakoids, grana, and stroma are, and give the function of
each.
3. Where
does the mass of a plant come from? How
was it determined that vegetation can restore air?
4. What
is light? What is the relationship
between the energy of a photon of light and the wavelength of light?
5. What
is an absorption spectrum?
6. What
is a pigment? Why do pigments appear to
have a certain color?
7. What
is the absorption spectrum of chlorophyll?
8. What
are the components of a photosystem and how do they function to translate light
energy into reducing power?
9. What is the purpose of the light
reactions? Where in the chloroplast do
they occur? What is the role of water in the light reactions? What products are
produced? How are they produced? What are they used for?
10. What
is the purpose of the Calvin cycle? What reactants are required? What are they used for? What products are produced?
11. What
is photorespiration? What does photorespiration cost the plant. What environmental conditions promote
photorespiration? Describe two
strategies used by plants for decreasing the costs of photorespiration.
