1. Select the term from each drop down box to correctly complete each sentence.(2 points)
The process of photosynthesis is essential in the carbon cycle. Photosynthesis removes
from the atmosphere and produces/releases
back into the atmosphere.
The correct answer is chloroplasts and mitochondria. chloroplasts are involved in converting energy during photosynthesis, while mitochondria are involved in converting energy during cellular respiration.
The process of photosynthesis is essential in the carbon cycle. Photosynthesis removes carbon dioxide from the atmosphere and produces/releases oxygen back into the atmosphere.
2. A student is completing an experiment comparing plants in two areas. Both areas have the same type of plants with equal sunlight and equal available water. Area 1 has a high amount of carbon dioxide in the atmosphere, and area 2 has a low amount of carbon dioxide in the atmosphere.
How does the rate of photosynthesis in area 1 compare to the rate of photosynthesis in area 2?
(1 point)
Responses
The rate of photosynthesis increases with an increase in carbon dioxide; therefore, area 1 will have a higher rate of photosynthesis compared to area 2.
The rate of photosynthesis increases with an increase in carbon dioxide; therefore, area 1 will have a higher rate of photosynthesis compared to area 2.
The rate of photosynthesis increases with a decrease in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The rate of photosynthesis increases with a decrease in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The rate of photosynthesis decreases with an increase in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The rate of photosynthesis decreases with an increase in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The amount of carbon dioxide in the atmosphere has no affect on the rate of photosynthesis; therefore, area 1 and area 2 will have the same rate of photosynthesis.
The rate of photosynthesis increases with an increase in carbon dioxide; therefore, area 1 will have a higher rate of photosynthesis compared to area 2.
Plants are known as autotrophs. That means that they can make their own food. Plant cells do so by taking in
gas and
. Those are the
used in the chemical reactions that occur during photosynthesis.

4. During the processes of photosynthesis and cellular respiration, energy is converted. The law of conservation of energy is observed. Which cell organelles are involved in converting energy from one form to another?(1 point)
Responses
cell membrane and golgi body
cell membrane and golgi body
nucleus and cytoplasm
nucleus and cytoplasm
chloroplasts and mitochondria

5. Plants use the solar energy in sunlight to drive photosynthesis and produce glucose. The energy stored in the glucose is then released by the process of _____.(1 point)
Responses
photosynthesis
photosynthesis
cellular respiration
cellular respiration
genetic engineering
genetic engineering
protein synthesis
The correct answer is cellular respiration. The energy stored in glucose produced during photosynthesis is released by the process of cellular respiration.
6. Jaylah and Simon were discussing what they learned in Science class today. Jaylah asked Simon the following question, "If oxygen is removed from a plant's environment, what would you expect to happen to the plant's ability to break down glucose sugar and produce the energy molecule of ATP?"
What is the correct response that Simon should give Jaylah?
(1 point)
Responses
The plant's ability to break down glucose sugar and produce the energy molecule of ATP would be affected because photosynthesis would not have a needed reactant to undergo all the chemical reactions.
The plant's ability to break down glucose sugar and produce the energy molecule of ATP would be affected because photosynthesis would not have a needed reactant to undergo all the chemical reactions.
The plant's ability to break down glucose sugar and produce the energy molecule of ATP would not be affected because photosynthesis should occur normally.
The plant's ability to break down glucose sugar and produce the energy molecule of ATP would not be affected because photosynthesis should occur normally.
