  • 2. 

    Trematodes are

    • Biter

    • Sucker

    • Slapper

    Correct Answer
    A. Sucker
    Explanation
    Trematodes are a type of parasitic flatworms that have a specialized organ called a sucker. This sucker allows them to attach to the tissues of their host and feed on their blood or bodily fluids. The sucker helps them to stay firmly attached and ensures a continuous food supply. Therefore, "sucker" is the correct answer as it accurately describes one of the defining characteristics of trematodes.

    Trematodas intermediate host

    • Cat

    • Human

    • Snail

    • Pigs

    Correct Answer
    A. Snail
    Explanation
    Trematodes are a class of parasitic flatworms that require an intermediate host to complete their life cycle. The given options are potential intermediate hosts for trematodes. Out of the four options, snails are commonly known to be intermediate hosts for many species of trematodes. They play a crucial role in the transmission of trematode parasites to their definitive hosts, such as cats, humans, and pigs. Snails serve as a suitable environment for the development and reproduction of trematodes, allowing them to infect other organisms in their life cycle.

  • 4. 

    They are also called leaf-shaped worms.

    • Cestodes

    • Protozoa

    • Trematodes

    Correct Answer
    A. Trematodes
    Explanation
    Trematodes are also called leaf-shaped worms because they have a flat and elongated body shape that resembles a leaf. This characteristic shape is a distinguishing feature of trematodes and sets them apart from other organisms like cestodes and protozoa. Trematodes are a type of parasitic worm that commonly infects humans and animals, and their leaf-like body shape allows them to attach and feed on the internal organs of their hosts.

    Rate this question:

  • 5. 

    Trematodes are members of what Phylum?

    • Platyhelminthes

    • Helminthes

    • Both

    Correct Answer
    A. Platyhelminthes
    Explanation
    Trematodes are members of the Phylum Platyhelminthes. Platyhelminthes, also known as flatworms, is a phylum that includes various types of worms, including trematodes. Trematodes are a type of parasitic flatworm that commonly infects humans and animals. They have a flattened body shape and are characterized by their complex life cycles, often involving multiple hosts. Therefore, the correct answer is Platyhelminthes.

    Rate this question:

  • 6. 

    One or more sexually reprodcing embryonic stages collectively refered to as

    • Polyembryony

    • Polymorphic

    • Both

    • None

    Correct Answer
    A. Polyembryony
    Explanation
    Polyembryony refers to the phenomenon where multiple embryos develop from a single fertilized egg. This can occur in some species through various mechanisms such as cleavage of the zygote, formation of multiple embryos within the same egg, or division of the early embryo. Therefore, the correct answer is "polyembryony" as it represents the occurrence of multiple sexually reproducing embryonic stages.

    Rate this question:

  • 7. 

    Trematoda means;

    • Happy worms

    • Body without anus

    • Body with holes

    • Both A & B

    Correct Answer
    A. Body with holes
    Explanation
    Trematoda refers to a class of parasitic flatworms that have a body with holes. These holes, known as suckers, are used by the worms to attach themselves to the host's tissues and feed on their blood or bodily fluids. This characteristic distinguishes them from other flatworms and is an important feature of their anatomy and lifestyle.

    Rate this question:

  • 8. 

    All Tremadoda are Heteroxenous

    • True

    • False

    Correct Answer
    A. True
    Explanation
    All Tremadoda are heteroxenous, meaning that they have multiple hosts during their life cycle. This is a characteristic feature of Tremadoda, a class of parasitic flatworms. Heteroxenous parasites require different hosts to complete their life cycle, often involving intermediate hosts and definitive hosts. Therefore, it can be concluded that the statement "All Tremadoda are heteroxenous" is true.
