In order for a lymphocyte to respond to an antigen, must the antigen be phagocytized by the lymphocyte? Must the antigen enter the cytoplasm of the lymphocyte?

Please see the explanation.
Explanation:
Well, this is called immunological response.
There are several factors that are involved in this process. If we speak about the infection caused by bacteria on a place where necrosis has already occurred, in the differential blood specimen, neutrophils will be present the most among the other lymphocytes.
Generally, in the blood, when allergy occurs, the responding lymphocyte is the T-lymphocyte. Now, the response is inducted by the T(h)-lymphocyte and T(c)-lymphocyte. Also, there are B-lymphocytes.
If the B-lymphocyte interacts with antigen it reproduces itself and reproduce antigens.
T(h)-lymphocyte inducts T(c)-lymphocyte. If the antigen of a T(c) lymphocyte responds to the antigen of the bacteria, for example, then it will be engulfed. So, the antigen of of bacteria has to be recognized by the lymphocyte to be engulfed.
You can find more about immunological responses on the Khan Academy where it is explained pretty much in detail (for a high school student).
