Final answer:
Follicular dendritic cells are the cells in the light zone of a germinal center that hold antigens for B cells to bind to.
Step-by-step explanation:
In the light zone of a germinal center, the cells that hold antigens for B cells to bind to are follicular dendritic cells. These cells play a crucial role in presenting antigens to B cells, allowing them to recognize and respond to specific pathogens or foreign substances.
Follicular dendritic cells have specialized features that enable them to capture and retain antigens, such as their ability to form long extensions called dendrites, which allow them to interact with B cells.
The cells you would expect to find in the light zone of a germinal center that hold antigen for B cells to bind to are follicular dendritic cells. These cells present antigens to the B cells to promote the immune response.
