The more common name for the tree is a sycamore fig, sycomore fig, or a fig mulberry. The trees do produce fruits, like other figs, but they tend to be small. Yet they are still edible and the tree is cultivated for its fruit. The sycamore fig is mentioned in I Chronicles 27:28; Psalm 78:47; Amos 7:14; and Luke 19:4. The Hebrew name for the tree is shaqam and its Greek name is sukomoraia. In England, a sycamore is a type of maple tree (acer pseudoplatanus).

Naive B cell. A naÃ¯ve B cell is a B cell that has not been exposed to an antigen. Once exposed to an antigen, the naÃ¯ve B cell either becomes a memory B cell or a plasma cell that secretes antibodies specific to the antigen that was originally bound. Plasma cells do not last long in the circulation, this is in contrast to memory cells that last for very long periods of time.
