Definition of Porifera Porifera are asymmetrical or radially symmetrical multicellular organisms with a cellular grade of organisation lacking well-defined tissues as well as organs; exclusively aquatic; mostly marine, sedentary, solitary or conical animals with a body perforated by pores, canals, as well as cambers through which water flows; with one or more internal cavities lined … Read more

Dissecting Microscope (Stereo Microscope) Definition, Principle, Uses, Parts

Dissecting Microscope Parts (Stereo microscope)

Dissecting Microscope (Stereo Microscope) Dissecting Microscope or Stereoscopic microscopes are another name for these. Dissection microscope is a digital optical microscope having low magnification power (5x-250x) which uses light reflected from the specimen’s surface instead of light reflected from the specimen itself. Its principal function is to dissect specimens as well as observe as well … Read more

Epithelial Tissue Vs Connective Tissue: Definition, 16+ Differences, Examples

Definition of Epithelial Tissue Epithelial tissue is a kind of animal tissue which is composed of highly aggregated polyhedral cells which are tightly attached to each other as cellular sheets which line the inside of hollow organs and cover the body surface. Cells in epithelial tissue or epithelium (plural: epithelium) are organized in continuous sheets, in … Read more

Differences Between Arteries and Veins

 Arteries and Veins Arteries and veins are two of the most common types of blood vessels in the body, through which blood flows. The arteries transport oxygenated blood out from the heart, whereas the veins transport deoxygenated blood from the tissue capillaries back to the heart.

Eukaryotic Cells: Definition, Parts, Structure, Examples

Eukaryotic Cells: Definition, Parts, Structure, Examples

Definition of Eukaryotic Cells Eukaryotic cells feature a membrane-bound, well-defined nucleus as well as several membrane-bound organelles, making them complicated in structure as well as function. The term “eukaryote” comes from the Greek words “eu” as well as “karyon,” which mean “true” as well as “nucleus,” respectively. When compared to prokaryotes, eukaryotic cells have a … Read more

Glandular Epithelium: Location, Structure, Functions, Examples

Definition of Glandular Epithelium In addition to the covering as well as lining epithelium, the glandular epithelium is a collection of tissues which specialise in the production and secretion of various macromolecules. Because of its primary function, the glandular epithelium is also referred to as the secretory epithelium. This epithelium is found beneath the covering and … Read more

25+ Differences between Invertebrates and Vertebrates

Differences between Invertebrates and Vertebrates

Differences between Invertebrates and Vertebrates Invertebrates (non-chordates) and vertebrates (living things)  (Chordates) make up the majority of the animal kingdom. Those without a vertebral column or backbone are called invertebrates, while those with one are called vertebrates. Characteristics Invertebrates (Non-Chordates) Vertebrates (Chordates) Radial Bi-radial, or not present Bilateral Symmetry Metamerism True or pseudo metamerism or not present True … Read more
