To encourage the reappearance of bubbles caused by photosynthesis in the aquatic plant, the scientist should add carbon dioxide to the water. Plants need carbon dioxide, along with sunlight and water, to perform photosynthesis and produce oxygen, which is what causes the bubbles to form on the leaves.
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. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be added to the water in order for the bubbles to reappear. (1 point) Responses glucose glucose oxygen oxygen hydrogen gas hydrogen gas carbon dioxide
