Note the following :
(A) Monocytes, (B) Trophocytes, (C) Lymphocytes, (D) Mycetocytes, (E) Leucocytes, (F) Oenocytes, (G) Urate cells
Which of the above are present as fat cells in Periplaneta?
Trophocytes, mycetocytes, oenocytes as well as urate cells are the fat bodies of Periplaneta. Here, trophocyte contains the reserve food to help them during their starvation. Also, mycetocyte contains symbiotic bacteria like Buchnera species. Ooenocytes are responsible for lipid processing and detoxification. And urate cell contains the uric acid.
