Answer:
Glucose
Explanation:
ATP, Carbon Dioxide, and Water are all results of Cellular Respiration and do <em>not</em><em> </em>form during Photosynthesis. These three are actually used in the process of Photosynthesis, so they are not created by it. Plants use photosynthesis to create their own glucose.
It is important because it creates a second copy of DNA that must go into one of the two daughter's cells when a cell divides
The effect does the chemical referred to as a mutagen has is it causes a permanent change in the genetic material (dna) and is denoted as option D.
<h3>What is DNA?</h3>
This is referred to as deoxyribonucleic acid and is the genetic material in living organisms.
Mutagen on the other hand are agents which cause mutations which means alterations in the DNA of organisms. It affects the transcription and replication of the DNA thereby leading to cell death and other effects such as diseased condition.
This is therefore the reason why option D was chosen as the most appropriate choice.

Robert Hooke observed the cells through a combination of lenses.
After Robert Hooke, the development of microscopy take place. After the development of the microscopy, scientist were able to observe the features of the cell. In order to formulate a cell theory observation of most of the cells was necessary. So, it was necessary to observe different types of cells from different organism. So, the advancement of the microscopy and observation process required for the formulation of the cell theory was the reason for the delayed development of the cell theory.
