Chapter 17, Problem 5RQ
Summary Introduction
Euglenids and kinetoplastids belong to Excavata group of protists. Members of kinetoplastids are characterized by presence of kinetoplast which is a compact mass of kDNA (which is a circular DNA), present in the single mitochondria. Euglenids comprise non-pathogenic and motile organisms which show phototrophic and chemotropic mode of nutrition.

Which of the following processes are involved in thereproduction of protists ?(a) Binary fission and budding(b) Cell fusion and zygote formation(c) Spore formation and cyst formation(d) All of the above
Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.
Which of the following is NOT true of protists?
Select one:
a. Some are unicellular.
b. They may be photosynthetic.
c. They are usually aerobic, though some are not.
d. They may have cell walls.
e. They may be prokaryotic.
You are given five test tubes, each containing an unknown protist, and your task is to read the description below and match these five protists that you know to the correct test tube.
-Paramecium
-Pfiesteria (dinoflagellate)
-Navicula (diatom)
-Plasmodium
-Amoeba
In test tube 1, you sketch the organism and come up with a picture that looks like the one below. You note the organism appears to be “eating” the smaller microorganism.
Chemical analysis of test tube 2 indicates the presence of a chemical that is toxic to fish and humans.
In test tube 3, you detect the presence of substantial amounts of silica.
Microscopic analysis of organisms in tube 4 reveals the presence of an apicoplast in the organism
Microscopic analysis of the contents in tube 5 reveals the presence of one large macronucleus and several small micronuclei in each organism
Match the description with the correct protist
