Photosynthesis Quiz

The reactants in the process of photosynthesis are:
1. NADPH and ATP
2. carbob dioxide and water
3. sugar and oxygen
4. chlorophyll and sunlight
The products of photosynthesis are
1. NADPH and ATP
2. carbon dioxide and water
3. sugar and oxyen
4. chlorophyll and sunlight
Green leaves kept in the dark for several days are tested for starch and no starch is found. This observation could best be accounted for by the hypothesis that
1. . the starch has been turned into sugar and then into ATP
2. Light is necessary for starch production
3. the chlorophyll has been used by the plant for food.
4. Both A and B are correct
In photosynthesis, light energy is captured by the:
1. grana
2. chlorophyll
3. electrons of the water
4. stroma
In what parts of the chloroplast do the two phases of photosynthesis occur?
1. Light phase in the grana, Dark phase in the stroma.
2. Light phase occurs in the stroma, Dark phase in the grana
3. Both occur in the mitochondria
4. Both occur in the grana
Plants store their energy as
1. nucleic acids
2. proteins
3. lipids
4. carbohydrates
Leaves of a plant appear green because
1. they absorb only green wavelengths
2. green represents the combination of many other wave lengths
3. they absorb other wave lengths and reflect green
4. they reflect violet and absorb green
Carbon 14, a radioactive form of carbon, can be used to mark carbon dioxide molecules. If a plant is grown in a sealed container that contains only marked carbon dioxide, the Carbon 14 will appear first in the
1. mitochondria
2. endoplasmic reticulum
3. chloroplast
4. nucleus
The snow plant in the Sierras is red in color and contains no chlorophyll. This plant is unable to use
1. carbon dioxide
2. water
3. oxygen
4. soil minerals
As temperature increases, photosynthesis
1. increases consistently if there is good light
2. increases consistently if there is poor light
3. increases until 35 degrees Celsius (about 95 F) if good light is available
4. increases regardless of the light intensity.
Dissolved oxygen used by fish and other ocean animals comes from the
1. process of photosynthesis carried on by phytoplankton
2. oxidation of salts dissolved in ocean water
3. chemical breakdown of ocean sediments
4. decomposition of dead organisms on the ocean floor.
Which energy conversion occurs during the process of photosynthesis?
1. chemical bond energy to light energy
2. light energy to mechanical energy
3. mechanical energy to radiant energy
4. light energy to chemical bond energy
The raw materials for photosynthesis are
1. oxygen and carbon dioxide
2. carbon dioxide and water
3. oxygen and water
4. sugar and carbon dioxide
Which summary word equation best describes a process that directly requires light energy?
1. glucose + oxygen = carbon dioxide + water + ATP
2. glucose + glucose = maltose + water
3. glucose =alcohol + carbon dioxide + ATP
4. water + carbon dioxide =glucose + oxygen
A small piece of black paper was folded in half and used to part of the top and bottom portions of a leaf on a living geranium plant. After the plant was kept in sunlight for days, the paper was removed. The leaf was then boiled in alcohol to remove the chlorophyll and placed in Lugol's solution. Only the part of the leaf that had not been covered turned blue black. This investigation was most likely testing the hypothesis
1. light is necessary for photosynthesis to occur
2. green plants use carbon dioxide in photosynthesis
3. alcohol plus chlorophyll forms Lugol's solution
4. plants use alcohol in the production of chlorophyll
The chief purpose of the photosynthetic process is considered to be the
1. production of water
2. production of carbon dioxide
3. production of chlorophyll
4. the conversion of light energy to chemical energy
