Types of B Cells

Q.

Which of the following statements are true for B cells?

1. Plasma B cells are short lived but have long lasting memory of the antigen

2. Memory B cells are short lived but have long lasting memory of the antigen

3. Memory B cells live longer and also have long lasting memory

Q.

Why do you think memory B cells are long lived ?

1. They have to remember the pathogen so if they die soon it will not be helpful
