A student performed an investigation to determine if the rate of photosynthesis in elodea, an aquatic plant, is aected by a higher than normal concentration of carbon dioxide gas in the water in which the plant is growing. After increasing the concentration of carbon dioxide in water, the student illuminated the plant and collected the bubbles of oxygen gas that were given from the cut end of the submerged plant. In this investigation, what would be the bestindicator of the rate of photosynthesis?

The amount of oxygen collected over a period of 12 hours

Use the information below to answer the question(s) below. In a lab study, eight bean plants are grown from seeds in individual containers. After a few leaves are visible on each plant, the plants are separated into two groups. One group is placed in a room that gets sunlight, and the other group is placed in a dark room. All of the plants receive the same amount of water daily. After two weeks, the plants are observed. Plants use energy from the sun to convert

carbon dioxide and water to sugars
