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.
Plants in Area 1 Plants in Area 2
same sunlight same sunlight
same water same water
same type of plant same type of plant
Consider how the following changes might affect the photosynthesis rate for the plants in area 2.
a. What would happen if the student reduced the amount of carbon dioxide available for plants in area 2?
(1 point)
Responses
The plants in area 2 would have a lower rate of photosynthesis than the plants in area 1.
The plants in area 2 would have a lower rate of photosynthesis than the plants in area 1.
The plants in area 2 would have a faster rate of photosynthesis than the plants in area 1.
The plants in area 2 would have a faster rate of photosynthesis than the plants in area 1.
The plants would both experience a reduced rate of photosynthesis.
The plants would both experience a reduced rate of photosynthesis.
The plants would have the same rate of photosynthesis.
b. What would happen if the student increased the carbon dioxide available for the plants in area 2?(1 point)
Responses
The plants in area 2 would photosynthesize faster than the plants in area 1.
The plants in area 2 would photosynthesize faster than the plants in area 1.
The plants in area 2 would photosynthesize slower than the plants in area 1.
The plants in area 2 would photosynthesize slower than the plants in area 1.
The plants in area 2 would stop photosynthesizing.
The plants in area 2 would stop photosynthesizing.
The plants in area 1 would stop photosynthesizing.
The plants in area 1 would stop photosynthesizing.
what about in area 1?
Increasing the carbon dioxide available for the plants in area 2 would not have an impact on the photosynthesis rate of the plants in area 1.
pick one of the answer choices
The plants in area 2 would have a lower rate of photosynthesis than the plants in area 1.
The plants in area 2 would have a lower rate of photosynthesis than the plants in area 1.
The plants in area 2 would have a faster rate of photosynthesis than the plants in area 1.
The plants in area 2 would have a faster rate of photosynthesis than the plants in area 1.
The plants would both experience a reduced rate of photosynthesis.
The plants would both experience a reduced rate of photosynthesis.
The plants would have the same rate of photosynthesis.
The correct answer for question a is: The plants in area 2 would have a lower rate of photosynthesis than the plants in area 1.
a. If the student reduced the amount of carbon dioxide available for plants in area 2, the plants in area 2 would have a lower rate of photosynthesis than the plants in area 1. This is because carbon dioxide is one of the essential components required for photosynthesis. By reducing the amount of carbon dioxide, the plants in area 2 would not be able to efficiently perform photosynthesis, resulting in a lower rate compared to the plants in area 1.
b. If the student increased the carbon dioxide available for the plants in area 2, the plants in area 2 would photosynthesize faster than the plants in area 1. This is because an increased amount of carbon dioxide would provide more raw material for the process of photosynthesis. As a result, the plants in area 2 would have a greater supply of carbon dioxide, allowing them to perform photosynthesis at a faster rate than the plants in area 1.
