Latecia conducted an experimental investigation of the gas production of a water plant. She placed a beaker upside down over a water plant submerged in water and collected the gas that ghe water plant produced when kept in sunlight. After several days, a large bubble of gas collected in the upside-down beaker.

After several days, a large bubble of gas collected in the upside-down beaker contains OXYGEN.

Explanation:

Plants are known to be be autotrophic (producers) through the use of inorganic substance such as water, carbondioxide and light energy from sunlight in a process known as photosynthesis.

An experiment was carried out by Latecia for investigation of the gas production of a water plant. It's therefore expected that OXYGEN gas which is the by-product given off during photosynthesis in green plants would be collected from the upside down beaker as gas bubbles.
