AP BIOLOGY

Detailed explanation-1: -The gas collected is probably oxygen, as the plant is in bright sunlight, which means it is photosynthesizing. Plants take in CO2 and release oxygen during photosynthesis.

Detailed explanation-2: -Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

Detailed explanation-3: -What would you expect to happen to plants at a temperature greater than 45 degrees celsius? They will have a less than optimal rate of photosynthesis and it would probably cook.

Detailed explanation-4: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
