The oxygen by-product of photosynthesis is created by the splitting of <u>water</u> molecules to replace the electrons ejected from the reaction center of photosynthesis ii.
Photosynthesis is a process whereby organisms containing plastids like green plants and other microorganisms make glucose using carbon dioxide, water and energy from sunlight.
A significant by-product of this process is oxygen, used by animals for respiration. Photosynthesis is of two stages; the light stage, also called photosynthesis i and the dark stage, also called photosynthesis ii.
During the light stage, the energy from sunlight is used to split water molecule into electrons, hydrogen protons and oxygen. The electrons are transported by carriers and used up in the reaction center of photosynthesis ii, while the oxygen is given of as a by-product.

Explanation:
DNA replication is a process common to both prokaryotes and Eukaryotes with few differences and similarities.
<u>Differences:</u>
1. Origin of replication (ori) : is a sequence of the genome where initiation of replication takes place. Prokaryotes have only single ori while eukaryotes have multiple ori as the DNA is large in eukaryotes so require multiple or to replicate whole DNA.
2. Replication site: prokaryotes lack nucleus where DNA is present in the cytoplasm while eukaryotes posses nucleus which encloses DNA. Therefore, replication takes place in cytoplasm in prokaryotes while in the nucleus in eukaryotes.
<u>Similarities:</u>
1. Enzymes: both posses same enzymes for DNA replication like DNA helicase, primase, polymerase.
2. The direction of synthesis: the enzyme DNA polymerase synthesizes new strand of DNA in the same direction that is 5' to 3' direction.
Thus, marked answer in the table are correct answer.
Answer:
The answer is "The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose." Hope that helps! :)
