This option is correct because amoeba was discovered by Sir Ronald Ross, and not by R. V. Rosenhof.

Stichonematic flagella bear a single row of mastigonemes alongside the sheath, e.g. Euglena.

Reserve food material of Trypanosoma gambiense is in the form of volutin granules. Trypanosoma gambiense reproduces only asexually by binary fission.

Trichonympha are symbiotic flagellate found in the gut of termites and cockroaches.

This option is correct because monkeys serve as a reservoir host for Plasmodium. Female Anopheles mosquito serves as a vector. Gametophytes of Plasmodium are formed in the RBC of blood of man. Gametes are formed in the lumen of stomach of a mosquito.

This option is correct because the locomotory organs are absent in class Sporozoa.

This option is correct because Amoeba proteus is ammonotelic in nature.

This option is correct because Ceratium and Noctiluca show bioluminescence.

Correct answer. Balantidium, Giardia, Trypanosoma: All are internal parasite protozoa. Balantidium is a common intestinal parasite of vertebrates, found chiefly in amphibians and mammals. Giardia are found as parasites in the digestive tract of vertebrates. Trypanosoma are the endoparasites which reside in blood and cerebrospinal fluid of man.

This option is correct.

This option is correct because Plasmodium vivax (malaria parasite) completes its asexual part of life cycle in people and the sexual part in the female Anopheles mosquito (digenetic life cycle) and Trypanosam cruzi possesses a digenetic life cycle, involving a hematophagous insect vector and a mammalian host.

Sol-gel theory of locomotion of amoeba was given by Hymen in 1927 and further supported by Pantin (1923-196) and Mast (xx). Sol-gel theory is the most accepted theory for locomotion of amoeba.

This option is correct because amoeba shows positive behaviour towards darkness.

Correct answer. Lobopods: They are short, blunt, thick, finger-like outgrowth of ectoplasm with an axial core of endoplasm. For example, amoeba. Filopods: They are cylindrical, thread-like, formed entirely of ectoplasm and radiate from the body in all direction. For example, Radiolaria. Reticulopods: They are filamentous and form a network of pods. For example, Polystomella. Axopods: They are long, stiff, semi-transparent extensions of cytoplasm with pointed distal ends. For example, Actinophyrus.

This option is correct because the duration of exoerythrocytic cyle is 8 days in Plasmodium vivax, while it is 14-15 days in Plasmodium malariae. Incubation period is 12-14 days in Plasmodium vivax, while it is 20-24 days in Plasmodium malariae.
