1)Global warming is caused by:
A. the release of large amounts of carbon dioxide and methane into the atmosphere
B. The fixation of carbon dioxide through photosynthesis
C. Cellular respiration of anaerobic organisms in landfills of human waste
D. Holes formed in the ozone layer do to the release of volatile organic gases
2)Scientific studies into the quality of light that plants best utilize for photosynthesis are important because:
A.Research has shown that plants get more energy from photosynthesis by capturing green wavelengths of light
B.Research has shown that plants get more energy from photosynthesis from the blue and red wavelengths of light
C.Research has shown that plants get more energy from photosynthesis if they have all wavelengths that makes white light present
D.Research has shown that plants get more energy from the ultraviolet wavelengths of light
3) Analyzing the chlorophyll content of plants in important because
A. Plants have different colors of chlorophyll that have different efficiently
values.
B.Plants have different colors of chlorophyll that are adapted to different intensities of light
C.Plants have different colors of chlorophyll that are able to absorb different wavelengths of light
D. Plants have different colors of chlorophyll are adapted for seasons of the year
4) If part of a leaf is blocked from sunlight then:
A. That part will have fewer stomata
B. That part will become more susceptible to virus attack
C. That part will have less chlorophyll
E.Cells in that part will die
5) If plant cells are places in a solution with a very high concentration of sucrose, what would on observe?
A.Cells will expand til they burst
B. The cell membranes would expand, increasing the pressure on the cell walls
C.The cell membranes would shrink away from the cell walls
D.Sucrose can not pass through the membrane of the plant cell so would have no effect
6) A student using paper chromatography to separate the pigments in plant chlorophyll. She subjected 5 different plants to the chromatography process and found that
A. Different plants have varying amounts of chlorophyll
B. Different plants have varying types of chlorophyll
C. Plants have many pigments that make up the green colors of leaves
D. Most plants have the same chlorophyll types
7) Which removes more carbon dioxide from atmosphere than return?
A. A mature forest
B. Grasslands near a mature forest
C. Underbrush in a forest
D. an actively growing forest
A. the release of large amounts of carbon dioxide and methane into the atmosphere
B. The fixation of carbon dioxide through photosynthesis
C. Cellular respiration of anaerobic organisms in landfills of human waste
