Chloroplasts are organelles within plant cells that contain chlorophyll and are responsible for carrying out photosynthesis. This process which is utilised by plants to manufacture food, requires carbon dioxide and water which is then converted into glucose and oxygen. Therefore, the release of oxygen tells us that photosynthesis is occurring inside the chloroplast.
The correct answer is that it produces antibodies against the sensitizing antigen.
Plasma cells are formed in the bone marrow, the B cells divide into plasma cells, which generate molecules of antibody. Once discharged into the lymph and blood, these antibody molecules combine with the target antigen, that is, foreign substance and starts its destruction or neutralization.
