9. Photosynthesis

Introduction to Photosynthesis

Photosynthesis (UPDATED)

Photosynthesis

The main product of photosynthesis is:a) Glucose.b) Oxygen.c) Carbon dioxide.d) Water.e) Sunlight.

 No. This is not a source of the oxygen produced; the oxygen molecules in carbon dioxide become part of glucose. 

 No. The product of photosynthesis is glucose, so it is not a source. 

 No. These are just tracers used to find the molecular source of the oxygen. 

Think about the source of electrons for photosystem II.

The source of the oxygen produced by photosynthesis has been identified through experiments using radioactive tracers. The oxygen comes from __________.

Which of the following statements is a correct distinction between autotrophs and heterotrophs?
a. Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic.
b. Only heterotrophs require chemical compounds from the environment.
c. Cellular respiration is unique to heterotrophs.
d. Only heterotrophs have mitochondria.

Photosynthesis vs. Cellular Respiration

Photosynthesis Under the Microscope

 No. Although a chlorophyll molecule does contain carbon, chlorophyll is not the source of the carbon used to synthesize sugars. 

 No. The sun produces electromagnetic energy. 

 No. Although plants do obtain many trace elements and water from the soil, they get carbon from another source. 

Consider the nutrient requirements of plants.

In photosynthesis, plants use carbon from __________ to make sugar and other organic molecules.

Energy used to power photosynthesis &amp; ultimately cellular respiration originates from which energy source?a) Glucose.b) ATP.c) Carbon dioxide.d) The sun.

Which of the following reactants is reduced during the process of photosynthesis?a) Oxygen gas.b) Photons of light.c) Carbon Dioxide.d) Water.
