Antibodies are produced by plasma cells in response to antigens and are found in all body secretions. Antibodies are produced by plasma cells in response to antigens and are found in all body secretions. True False

The given statement is true.

Explanation:

The plasma B cells or plasma cells refers to the white blood cells, which develops within the bone marrow and produces enormous amounts of proteins known as antibodies. The production of antibodies takes place against the particular components known as antigens.  

With the help of blood plasma, the antibodies are transported from their site of origination to their target antigens, where they begin the process of destruction or neutralization.  

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
