Chap. 7 Photosynthesis Study Guide

Be very familiar with the following terms and how they apply to the study of photosynthesis:

photorespiration              stroma                        bundle sheath cells
stroma                        granum                        mesophyll cells
thylakoid                     ATP                           CAM plants
stoma (stomata)               NADP+        NADPH            C3 plants
photosystems I & II           chloroplasts                  C4 plants
Calvin - Benson cycle         chemiosmosis                  photosystems I and II
light-dependent cycle         photolysis                    chemoautotrophs


What are photoautotrophs? What sort of organisms can be photoautotrophs?

Know the parts of a chloroplast.

The various photosynthetic pigments and the colors of light they absorb and reflect

What is a photosystem?

Where the photosystems are located in a plant and the two types of photosystems

The reactants, products, and processes of the light and dark reactions (very important)

Know where in a chloroplast the two photosynthetic reactions take place

The difference between C3, C4, and CAM plants (why they have the designation and how they fix carbon under

adverse conditions) Know some examples of each type.

What does CAM stand for?

How ADP becomes ATP and when this occurs during photosynthesis

How NADP+ becomes NADPH; during which photosynthetic cycle, and the purpose of NADPH in photosynthesis

What is the hydrogen (electron) acceptor in the light-dependent reactions?
When is oxygen formed in photosynthesis?

From what molecule does the oxygen come from that is released during photosynthesis?

How does CO2 enter a plant?

How many CO2 molecules are needed to make one molecule of glucose?

Under what conditions does a plant undergo photorespiration? Why is this bad for the plant?
