Answer:

decreases a plant’s weight

Explanation:

Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.

Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.

Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.

Hence, the correct answer is "decreases a plant’s weight".
