In studying micrographs of an unusual protist that you found in a sample of pond water, you spot an organelle that you can't recognize. You successfully develop a method for growing this organism in a liquid in the laboratory. Describe ow you would go about finding out what this organelle is and what it does in the cells. Assume that you would make use of additional microscopy, cell fractionation, and biochemical tests.

answer; the correct answer is desert plants;

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
