The process of photosynthesis is essential in the carbon cycle. Photosynthesis removes carbon dioxide (CO2) from the atmosphere and produces/releases oxygen (O2) back into 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 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.

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)
During the processes of photosynthesis and cellular respiration, energy is converted. The law of conservation of energy is observed. The cell organelles involved in converting energy from one form to another are the chloroplasts (in photosynthesis) and mitochondria (in cellular respiration).

A scientist fills a glass container with water and places an aquatic plant inside the container, then closes the lid and places the container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant’s leaves on days 1 and 2, but no bubbles on day 3. If the scientist concludes that the bubbles were caused by photosynthesis, then which reactant should be added to the water in order for the bubbles to reappear?
(1 point)
Responses
carbon dioxide gas
carbon dioxide gas
oxygen gas
