Question

Lymphocytes can develop into cells that secrete defense proteins against disease. These cells are termed ________, while these proteins are called antibodies.

Answer 1

Answer:

Plasma cells

Explanation:

B lymphocytes are the lymphocytes that are produced and matured in the bone marrow. These lymphocytes interact with the antigen with their receptors present on their surface and after interaction, they convert into memory B cell and plasma B cell.

Plasma cells are specific cells which are responsible for producing and secreting specif proteins called antibodies which is responsible for elimination the pathogen. There are five types of antibodies IgA, IgD, IgG, IgM, IgE. Therefore the correct answer is plasmocytes or plasma cells.

Answer 2

Answer: B cells

Explanation:

lymphocytes produce antibodies - proteins (gamma globulins) that recognize foreign substances (antigen) and attach themselves to them. B lymphocytes (or B cells) are each programmed to make one specific antibody. When a B cell comes across its triggering antigen it gives rise to many large cells known as plasma cells. Each plasma cell is essentially a factory for producing antibody
