Phylum Porifera

Phylum Porifera is placed in the kingdom Animalia and regarded as the oldest animal group. The term Porifera merely refers to pore bearers that include Poriferans or pore bearing animals. Poriferans or sponges possess small pores on their entire body and some wide openings. The members of Phylum Porifera are metazoans that show a cellular …

Gluconeogenesis

Gluconeogenesis occurs in a reverse manner of glycolysis, which produces glucose by the precursors like pyruvate, lactate, glucogenic amino acids. It is sometimes called Neoglucogenesis. It is a ubiquitous or universal pathway, which occurs in humans, animals, plants, fungi and other living organisms. Gluconeogenesis has only three irreversible steps opposite the glycolysis pathway, while the …

Cytoplasmic Inheritance

Cytoplasmic inheritance also termed as maternal inheritance or maternal effect. A cytoplasm comprises some autonomous organelles like mitochondria and plastids that possess their own genetic material. Mitochondria is present in both animal and plant cell, whereas plastids are only found in the plant cell. As we know, nucleic acids like DNA and RNA are responsible …

Qualitative Analysis of Carbohydrate

The qualitative analysis of carbohydrate is the significant test for detecting and classifying the carbohydrate, depending on the colour change followed by the chemical reactions. Carbohydrate is an organic biomolecule that is having a chemical formula Cm (H2O) n. The carbohydrate consists of three atoms viz. carbon, hydrogen and oxygen as the main constituent, where the …

Difference Between Spermatogenesis and Oogenesis

The difference between spermatogenesis and oogenesis is mainly due to the following factors like the process, occurrence and the product formed after gametogenesis. Process: The process of spermatogenesis and oogenesis is different, in which a former produce sperm cells from a spermatogonium and the latter produce ovum from an oogonium. Occurrence: Spermatogenesis occurs inside the …

Difference Between Voluntary and Involuntary Muscle

The difference between voluntary and involuntary muscle is mainly due to their functional property. The functioning of a voluntary muscle is in our control or controlled by the somatic nervous system. Oppositely, the functioning of an involuntary muscle requires brain input, or it is controlled by the autonomic nervous system. Voluntary muscle and involuntary muscle …
