Cellular Respiration

Cellular Respiration Definition Cellular respiration is a metabolic process consisting of a series of steps to convert chemical energy (sugar) into a usable form of energy (ATP) in the cell. The reactions involved in cellular respiration are catabolic reactions that involve the breakdown of larger organic molecules into smaller forms. The overall process of cellular respiration takes place in a …

3D Bioprinting- Definition, Principle, Process, Types, Applications

What is 3D Bioprinting? 3D Bioprinting is the method of printing biomedical structures with the use of viable cells, biological molecules, and biomaterials. In simple words, 3D bioprinting is the deposition of biological material in a layer-by-layer fashion to create 3D structures like tissues and organs. Bioprinting is considered a part of additive manufacturing that involves the formation of materials …

Cell Cycle- Definition, Phases, Regulation and Checkpoints

Cell Cycle

Cell Cycle Definition The cell cycle is the sequence of events occurring in an ordered fashion which results in cell growth and cell division. The cycle begins at the end of each nuclear division and ends with the beginning of the next. A cell cycle acts as a unit of biological time that defines the life history of the cell.  …

Streptococcus bovis- An Overview

Streptococcus bovis

What is Streptococcus bovis? Streptococcus bovis is a Gram-positive bacterium that belongs to the bovis/equinus complex of the viridans Streptococci. It is present in the gastrointestinal tract of humans as a normal inhabitant, along with other Streptococcus species. However, it is present in much fewer numbers than other such species. Previously S. equinus and S. bovis were considered as two …

Staphylococcus hominis- An Overview

Staphylococcus hominis

What is Staphylococcus hominis? Staphylococcus hominis is a Gram-positive coagulase-negative member of Staphylococci that exists as a commensal on the human body, especially in the areas with apocrine glands, axillae, and the pubic region. Like most other coagulase-negative Staphylococci, S. hominis is also known to cause various nosocomial or hospital-acquired infections and may occasionally cause infection in patients with abnormally …

Phylum Echinodermata- Characteristics, classification, examples

Phylum Echinodermata

Echinodermata (Echinoderms) Definition Echinoderms are enterocoelous coelomates with pentamerous radial symmetry, without distinct head or brain having a calcareous endoskeleton of separate plates or pieces and a peculiar water vascular system of coelomic origin with podia or tube-feet projecting out of the body. Phylum Echinodermata Characteristics They are exclusively marine and are among the most common and widely distributed marine …

Phylum Coelenterata

Coelenterata (Cnidaria) Definition The Coelenterata may be defined as diploblastic metazoa with tissue grade of construction having nematocyst and a single gastrovascular cavity or the coelenteron. Phylum Coelenterata (Cnidaria) Characteristics They are aquatic, mostly marine except few freshwater forms like the hydra. They are multicellular with tissue grade of organization. They are solitary or conical. Sedentary or free-swimming. Individuals are …

Phylum Hemicordata

Hemichordata Definition Hemichordata (Gr., hemi, half; chorde, cord) means they are ‘half’ of ‘part’ chordates, a fact that is disputed. They are usually vermiform, solitary, or colonial enterocoelous coelomate animals with an intra-epidermal nervous system and a pre-oral with or without gill-slits and without typical nephridia. Phylum Hemichordata Characteristics They are exclusively marine, solitary or colonial, mostly tubicolous. Their body …

Phylum Arthropoda- Characteristics, classification, examples

Phylum Arthropoda

Arthropoda (Arthropods) Definition Arthropods are bilaterally symmetrical, triploblastic, metamerically segmented animals with coelom which is reduced and modified. Their body is covered externally in a chitinous exoskeleton which molts periodically and their appendages are joined. Phylum Arthropoda Characteristics They are bilaterally symmetrical, triploblastic, metamerically segmented animals. Body organization is of an organ-system level. The body is covered with a thick …
