Hello. You forgot to add the chart. The chart is attached below.

Increased concentration of glucose in leaf cells

Explanation:

The chart below shows the essential events for photosynthesis to occur.

In the chart we can see that it is necessary that the plant be exposed to the sun, increase the use of CO2 and increase the concentration of glucose in the leaf cells. These events must happen in that order for photosynthesis to be efficient.

Photosynthesis, a term that means "synthesis using light", is generally defined as the process by which an organism manages to obtain its food. This process is carried out thanks to solar energy, which is captured and transformed into chemical energy. The photosynthesis process occurs in tissues rich in chloroplasts, one of the most active tissues being the chlorophyll parenchyma found in the leaves.

that is wrong, its not thymus.

the answer to your question is tooth decay.
