Question

I bolded my questions below, any help is greatlyappreciated. Thank you. Little intro: I'm taking an introduction course inenviornmental engineering and i've never taken a bio class in mylife but i'm not completely air headed (i think) and i've lookedsome stuff up so use big words, but not too big of words please oratleast explain yourself when you use wierd words to help me out:D. Now, we're learning microorganisms that can contaminate wastewater and Flagellates is one type of species we'reinterested. We have a lab coming up in which we need to lookunder a microscope and tell the organisms apart, and label themcorrectly. So i wrote down some characteristics forFlagellates (have flagellas "tails", multiply by binary fission,can form cysts (?), cytosomes may be present (?)). I'mwondering how fast is the binary fission proccess, so if Iwas looking under a microscope is it fast enough for me to possiblysee it happening or are there certain conditions that must be metin order for it to happen? Also, cysts? the defenition i was given is that theyare capsule-like "covers" that form around the microorganisms, butcan someone give me a very breif explanation and perhaps areference to a picture or two, or better yet a website coveringthis material. And finally, i came to understand that cytosomes arethe more viscous region of the cytoplasm of a cell, but how doesthat and this fall into the same category? I guess what i'm tryingto ask is do i look at microorganisms as "cells", and how could isee a cytosome under a microscope? I bolded my questions below, any help is greatlyappreciated. Thank you.

Explanation / Answer

Flagellates are unicellular Protozoans (Proto= first   Zoa= animal). They are characterized by presence of  vibratile flagella which   is alocomotory structure . As discussed they   are  unicellular   organisms ,they should have a mechanism   which serves   to propagate   them at a very high rate (As it is the rule of life ,simpler the organism higher is the rate of reproduction & viceversa). Therefore    binary fission ( Bi=two ; therefore each dividing cell willform two daughter cells)   is   an important mechanism forthese organisms as means of reproduction .The important conditions required are    optimal temperature conditions , abundance of   food (a general requirement of all the   growing populations). Cytosome (Cyto pertaining to cell ; Soma= body ) is synonym for   cytoplasm , which includes the cytoplasm along with it's   organelles.As discussed   flagellates are unicellular   organisms , they exhibit marked specialization   by performing    all  physiological   functions   of a multicellular organisms   by a single   cell . Therefore   in these organisms    cytosome is   divided   into two   parts   Exoplasm the outer   cytoplasm right against  the plasma membrane   &Endoplasm the   inner denser   part , where the cell organelle are present . Cyst is a hard ,sometimes spicular ,  resistant coat formed under unfavorable conditions i.e extremes of temperature conditions to prvent the organism from  dessication .It is made of polysaccharides mainly cellulose.Inside the coat the organism   in most cases remains dormant . As the favourable conditions return the cyst wall breaks to release the organism. Thus flagellates   are  cells    with   two important functional units i.e. the nucleus   & the  cytosome/cytoplasm.
