Question

question 7
how does oxygen production relate to the rate of photosynthesis?
o a the rate of oxygen production indicates the rate of photosynthesis
o b the rate photosynthesis decreases when oxygen production increases
o c oxygen production and photosynthesis are unrelated
o d photosynthesis continues even when no oxygen is produced

Explanation:

During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The more photosynthesis occurs, the more oxygen is produced. So, the rate of oxygen production can be used as an indicator of the rate of photosynthesis. Option b is incorrect because when photosynthesis rate increases, oxygen production should increase. Option c is wrong as oxygen is a product of photosynthesis. Option d is incorrect because in the light - dependent reactions (a part of photosynthesis where oxygen is produced), if no oxygen is produced, a key part of photosynthesis (related to the splitting of water in the light - dependent reactions) is not occurring properly and overall photosynthesis (in the context of oxygen - evolving photosynthesis) is severely affected.

Answer:

A. The rate of oxygen production indicates the rate of photosynthesis
