researching‚ I predicted that I would see different numbers of cells (which are the bubbles or the circles in all the different stages). I got some pictures from a website and I knew what to do‚ and how to tell how many cells are in each stage after staining the onion root tip. Procedure I did this project all on my own. I had to wait one day to get the microscope‚ I then got the onion root tip and sliced it into small pieces. I stained the root with red food coloring to make it more visible‚ and

Granulocytes (polymorphonuclear leukocytes): leukocytes characterised by the presence of differently staining granules in their cytoplasm when viewed under light microscopy. These granules are membrane-bound enzymes that act primarily in the digestion of endocytosed particles. There are three types of granulocytes: neutrophils‚ basophils‚ and eosinophils‚ which are named according to their staining properties. • Agranulocytes (mononuclear leukocytes): leukocytes characterized by the apparent
