Difference Between Flagella and Pili

The difference between flagella and pili is due to the difference in the properties like structure, origination and functional role. Both are the two common types of surface appendages, which aid in locomotion and attachment of the organisms. Structure: The structure of flagellum appears whip-like, whereas pili appear thread or hair-like. Origination: The emergence of …

Difference Between Amphibians and Reptiles

The difference between amphibians and reptiles is mainly due to the differences in the properties like the existence of dual life cycle, type of fertilization and skin type. Both amphibians and reptiles are the animals belonging to the phylum “Chordata” and considered as “Cold-blooded animals”. Life cycle: Amphibians have dual existence in their life cycle, …

Agglutination Reaction

Agglutination reaction is an immunological assay, which results in the specific antigen and antibody reaction in vitro. Agglutination purely refers to the clumping or aggregation of the particles. As a result of agglutination, a cross-linked structure or lattice appears in the form of visible aggregates. Agglutination reaction is a sensitive, easy and cost-effective method to carry …

Precipitation Reaction

A precipitation reaction is a test involved in the serology, for the qualitative and quantitative detection of antigens and antibodies. It is a reaction, where the soluble reactants (antigen and antibody) convert into an aggregated form. The sensitivity of the precipitation reaction is comparatively less than the other immunoassay reactions. For the precipitation reaction, polyclonal …

Difference Between Precipitation and Agglutination Reaction

The difference between precipitation and agglutination reaction is primarily due to the factors like the size of the antigen, solubility of antigen, and the reaction’s sensitivity. Both methods are prevalently employed to detect antigens and antibodies. Size of antigen: The size of the antigen in precipitation reaction is larger than the agglutination reaction. The solubility …

Post Harvest Loss

Post harvest loss is one of the biggest problems affecting economic growth globally. The FAO (Food and Agriculture Organization) estimates that 1/3rd of loss in the food products occur every year. The loss depends upon the type of crop that is to be cultivated. As the fruits and vegetables are perishable, so their chances are …

Phloem

Phloem is a complex tissue of a plant, first introduced by a scientist Nageli in 1853. It is a part of the plant’s vascular system that involves the translocation of organic molecules from the leaves to the different parts of plants like stem, flowers, fruits and roots. Numerous specialized tissues (vascular tissues) contribute to a …

Ovule

The ovule is a part of a plant that is popularly known as megasporangium. It is present inside the ovary base, which extends and gives rise to the stalk-like structure called style and finally opens into the stigma. Megasporangium can be defined as a large, sac-like structure, which gives rise to the production of the megaspores …
