Bilayer Cell Membrane

The bilayer cell membrane is a membranous structure, which consists of two phospholipid layer. Thus, a cell membrane also refers to as a phospholipid bilayer membrane. A cell membrane is composed of many phospholipid molecules. A structure of a phospholipid molecule consists of hydrophilic head, a phosphate molecule, a glycerol molecule and two hydrophobic fatty …

Gynoecium

Gynoecium also refers as “Carpel” or “Pistil” which primarily consist of three structures, namely stigma, style and ovary. It is the female reproductive part of the flower which carries the female gametes or ovules within an ovary. On the base of the gynoecium, pedicle or thalamus is present which provides support to the female reproductive …

Xanthophyll

Xanthophyll is a type of accessory pigment or phytochemicals which belongs to the class of “Carotenoids”. In many vascular plants and algae, xanthophylls act as the light harvesting protein complexes. Xanthophylls are rich in “Antioxidants” which prevents the cells from damaging. In photosynthetic eukaryotes, the xanthophylls are usually bound to the chlorophyll molecules. Xanthophylls are …

Difference Between Template and Coding Strand

The difference between template and coding strand is mainly due to the following properties like directional polarity and their function. Both are the two different strands of the double-stranded DNA, where template strand works as a template or base to transcribe mRNA, and the other determines the correct base sequence of the mRNA. Directional Polarity: …

Difference Between Flagella and Pili

Flagella and pili are the two surface appendages found commonly in prokaryotes. There are some significant differences between the flagella and pili which distinguishes both of them by the following properties like structure, emergence and functional role. Structure: The structure of flagellum is whip-like whereas the structure of pili is thread or hair-like. Emergence: The …

Difference Between Amphibians and Reptiles

Amphibians and reptiles are the animals which belong to the phylum “Chordata” and are “Cold-blooded animals”. The significant differences between amphibians and reptiles are due to the differences in the properties like life cycle, fertilization and skin type. Amphibians have dual existence in their life cycle, whereby getting birth they adapt themselves to the aquatic …
