Notes on Protozoa! Study of Protozoa or Protozoology has a direct bearing on other branches of Zoology. Protozoa occur as single cell and provide excellent materials for the study of the nature and mechanism of cellular activity at unit level. Information accrued from such studies gives a thorough comprehension of biology and Biological principles. Geneticists have focused their attention on [...]
The following points highlight the five main types of symmetry seen in animals. The types are: 1. Asymmetrical Symmetry 2. Spherical Symmetry 3. Radial Symmetry 4. Biradial Symmetry 5. Bilateral Symmetry. Type # 1. Asymmetrical Symmetry: In some animals there are no body axis and no plane of symmetry, hence the animals are called asymmetrical. The amoeboid forms (e.g., Amoeba) [...]
The upcoming discussion will update you about the difference between Protozoa and Metazoa. Difference # Protozoa: 1. Protozoans are unicellular animals. 2. Protozoans are generally microscopic. 3. Acellular or body is not differentiated into cells. 4. Single cell can perform all sorts of functions like a complete multicellular organism. 5. Single cell is capable of independent existence. 6. Body of [...]
