What is the definition of memory cells?

What are memory cells of immune system?
Lymphocytes that stay in the blood after an infection is gone
Which type of cells develop from clonal selection of lymphocytes?
Clonal selection of lymphocytes leads to the development of specific effector cells and memory cells. When a lymphocyte recognizes a specific antigen, it proliferates and differentiates into effector cells, such as plasma cells that produce antibodies, or cytotoxic T cells that kill infected cells. Additionally, some of the activated lymphocytes become memory cells, which provide long-lasting immunity by responding more rapidly upon subsequent exposures to the same antigen.
What is the function of B Lymphocytes?
IMPORTANCE OF B LYMPHOCYTES: 1.b lymphocytes play important role in humeral immune response. 2.they secretes antibodies. 3.they differentiate into memory and plasma cells.

What is the structure of T lymphocytes?
T lymphocytes are characterized by a round or oval nucleus with a small amount of cytoplasm. They have cell surface receptors that can recognize specific antigens presented by antigen-presenting cells. T lymphocytes differentiate into various subsets such as helper T cells, cytotoxic T cells, regulatory T cells, and memory T cells.
Do activated Tc cells only turn in to cytotoxic T-lymphocytes or do Tc differentiate into memory cells as well?
Activated Tc cells can differentiate into both cytotoxic T-lymphocytes, which directly kill infected or cancerous cells, and memory T cells, which are long-lived and provide a rapid response upon re-exposure to the same pathogen. This differentiation allows the immune system to mount a faster and more efficient response upon encountering the same threat in the future.
Antibodies are produced by what?
Plasma Cells, lymphocytes .
When an antigen triggers the multiplication of B lymphocytes some daughter cells transform into antibody-producing cells and mount an attack while others become?
memory cells
How long do lymphocytes live?
Lymphocytes can live for weeks to years, depending on the specific type. B cells can live for a few days to several weeks, while memory T cells can persist for a lifetime. Factors such as the type of lymphocyte, presence of infections, and overall health can influence their lifespan.
What kinds of lymphocytes are there?
Lymphocytes are a type of white blood cell. There are two kinds of lymphocytes. These are the T-cells and B-cells.
What are the immune cells that produce free antibodies?
B lymphocytes that will divide to form 1.plasma cells which produce specific antibodies and 2.memory cells which is the basis of immunological response.
