The given blank space in the statement, “Photosynthetic protists are collectively known as _; non-photosynthetic, single-celled protists are collectively known as _.” Introduction: The protists that are able to perform photosynthesis are called as algae. The non-photosynthetic protists are not able to perform photosynthesis and are known as protozoa. Some protozoa depend upon other animals to gain their nutrition.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

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
