Fasciola hepatica: Fasciola, often known as the common fluke, is a parasitic flatworm that lives in the liver and bile passages of vertebrates, including dogs, pigs, sheep, cattle, and rabbits. Fasciola hepatica An illness known as fascioliasis, or liver rot, is brought on by the several species of Fasciola, such as F. hepatica, the liver…
Reproduction in Paramoecium: Paramecium reproduces asexually by transverse binary fission and also undergoes several types of nuclear reorganisation, such as conjugation, endomixis, autogamy, cytogamy and hemixis, etc. Asexual Reproduction in Paramoecium Asexual reproduction is the more common mode of reproduction in protozoa. It allows for rapid population growth under favorable conditions. There are several forms…
Locomotion in Amoeba and Euglena: Locomotion refers to the ability of an organism to move from one place to another. In unicellular organisms, locomotion is typically achieved through specialized structures or cellular processes that propel the organism forward. Locomotion in Amoeba and Euglena Amoeba moves using a unique form of locomotion called amoeboid movement, which involves…
Importance of Zoology: Zoology is the scientific study of animals. It encompasses a vast array of topics, from the anatomy and physiology of individual creatures to the behavior and ecology of entire populations. Zoologists explore the diversity of animal life, from microscopic invertebrates to gigantic mammals, examining their structures, functions, classifications, habits, and interactions with…
Hemichordata: They are tongue worms, which have been included for long as a subphylum or class of Phylum Chordata in the lower chordates or Protochordata, but now they are placed as an independent phylum of invertebrates, since their supposed affinities with chordates are doubtful. Hemichordata are a small group of marine, solitary or colonial, worm-like,…

Phylum Protozoa: The Phylum Protozoa comprising a diverse group of unicellular organisms. Let’s explore their characteristics and classification. Defination: The Protozoa may be defined as ‘microscopic, acellular animalcules existing singly or colonies, without tissues and organs, having one or more nuclei. When in colonies, they differ from Metazoa in having all the individuals alike except…

Phylum Cnidaria: Cnidaria derives from the Greek word “cnidos,” which means “stinging thread.” Defination: The cnidaria may be defined as “diploblastic Metazoa with tissue grade of construction having nematocysts and a single gastrovascular cavity or the coelenteron.” The phylum Cnidaria is a large group of aquatic invertebrates, with over 11,000 described species. They are mostly marine…
