questions about photosynthesis

Question

1.  During the light reaction stage of photosynthesis which of the following occurs?

 

    a.  the simmple sugar glucose (C6 H12 06 is produced

    b.  chlorophll abosrobs light energy and uses it to split water molecules to form oxygen and hydrogen ions.

    c.   oxygen is released into the air

    d.   both b and c occur

 

   (Ithink the answer is B)

 

2.  during the dark reaction stage of photosynthesis which occurs?

 

    a,  chlorophyll absorbs light energy

    b.  water molecules split to form oxygen and hydrogen ions

    c.   hydrogen ions combine with carbon dioxide to produce the simple sugar glucose

    d.  both b and c occur

 

   (I think the answer is D)

 

3.  What nutrients are produced by plants from the product photosynthesis

    a. carbohydrates

    b. fats

    c. protein

    d. all of these

 

  (I think the answer is D)

 

4.  The process by which water evaporates through pores in the leaves of plants is called.

    a.   photosyntheis

    b.   fermentation

    c.   transpiration

    d.  respiration

  (I think the answer is C)

 

Answer 1

1. B, light reaction consists of electron and proton transfer.

 

2. C, consists of carbohydrate/sugar synthesis from CO_2.

 

3. A, proteins and fats are not produced by photosynthesis.

 

4. C, you got that right.

 

Hope this helps.
